Inmarsat just announced that new and existing IsatPhone 2 users can have free use of GEOS emergency response (SOS) service as long as they have an active postpaid airtime plan.
Not surprisingly, SOS functionality is of big importance to satellite phone users and many satellite phone manufacturers have incorporated a SOS button into the design of the phone itself. Now IsatPhone 2 users can use the handy "one-press assistance button" on the handheld phone to connect directly with GEOS.
GEOS's IERCC (International Emergency Response Coordination Center) is headquartered in Houston, TX and is staffed 24/7, 365 days a year.
Once the button is pressed on the IsatPhone 2, a message is automatically triggered that sends the user's GPS coordinates to the GEOS center. GEOS will contact the user directly and establish the nature of the emergency before then contacting the appropriate authorities for help or rescue, depending on the user's region and what type of emergency is at hand.
GEOS SOS Service FREE for IsatPhone 2 Postpaid Users
All postpaid IsatPhone 2 customers have access to this service for free as a new feature of their postpaid service. Inmarsat will begin including documentation on how to use the service and set it up with all new IsatPhone 2 phones shipped, but any existing IsatPhone 2 customer with an active postpaid account can register for this service now.
Register for free GEOS SOS satellite service here: www.geosalliance.com/inmarsat
What If I Have Prepaid Airtime for My IsatPhone 2 Satellite Phone?
If you have prepaid airtime for your IsatPhone 2 you can still sign up for GEOS service, but there will be an annual fee for the service.

XGate Satellite Data Service Now Offers FREE GRIB Weather Software and An Integrated GRIB Viewer At No Extra Cost
Now, with just a few clicks, XGate users can easily see weather forecast visualizations so they can make critical decisions based on weather patterns, and be confident on the water or in remote areas.
XGate Satellite Weather on iOS, Android, Mac, and Windows
There are many different options for getting weather over satellite, but the easiest is using the brand new built-in weather feature within XGate satellite data service. This compression data service allows you to send and receive email over very narrow bandwidth satellite devices (like a satellite phone).
The new weather feature in XGate has two different functions:
iOS and Android
From within the XGate app in iOS and Android, there is a full-featured weather forecast section that allows you to see the weather forecast and meteorological information about a chosen location.
Mac and PC
From within the XGate program on Mac and PC, there is a new GRIB file retrieval and viewer built directly into XGate. You can choose your location on a map and request and view weather information for that location (wind direction and speed, primary wave heigh, wave period, and wave direction, and convective precipitation).
Powerful GRIB File Weather Viewer
The GRIB file viewer that is now integrated in XGate is based on GRIBPlot - an easy-to-use GRIB viewer that also retrieves GRIB files through XGate's compression email service. GRIBPlot has many features for viewing GRIB files, including:
- Contour Data
- Vector Lines
- Bitmap Data
With the built-in GRIB viewer you can retrieve GRIB files by pointing the cursor over the geographical area where you would like weather information for and then clicking the "Email" button. This will send a request to your XGate outbox. When you're ready to download your GRIB file, you do a session in XGate, wait a minute or two, and then do another session to retrieve the GRIB file.
XGate uses Global Marine Network's popular GRIB retrieval system and can retrieve the following information for GRIB files:
The GRIB robot also has a batch mode to schedule GRIB files to be delivered to you daily.

For a limited time, trade-in your Iridium AxcessPoint device and get Optimizer for 50% off the retail price.
Iridium is discontinuing their Iridium AxcessPoint device. While this won't immediately affect AxcessPoint and AxcessPoint Mail & Web users, it does mean that in the future there won't be software updates or hardware service for AxcessPoint. If you upgrade your satellite phone or upgrade your computer or mobile device, the service may not work at all for you.
RedPort Optimizer vs AxcessPoint - Is it Worth Upgrading?
Aside from the fact that Optimizer is a rapidly growing, Iridium-certified product with no end in sight and excellent support to back it up, there are some tangible benefits to using Optimizer over the AxcessPoint.
- When using its external battery, the Optimizer's battery lasts more than 10 times longer than AxcessPoint's.
- Optimizer has a faster processor, which speeds up connections, updates, and bootup.
- Optimizer has a longer WiFi range.
- Optimizer has much better cross-platform integration.
And that's just the hardware. What about the software?
XGate or Iridium Mail & Web
Optimizer has traditionally only worked with XGate satellite email service (or one of the RedPort Optimizer-compatible services like Satphone.me, SpeedMail, and OCENS Mail, among others). Now, Iridium AxcessPoint Mail & Web users can use Iridium's free email program - now called Iridium Mail & Web - with the Optimizer.
Keep in mind, however, that Iridium Mail & Web only works with smartphones and tablets. Iridium's version that works with laptops and computers (called AxcessPoint Mail & Web) will be discontinued along with the AxcessPoint device.
XGate may be a better choice for many users because Iridium Mail & Web, along with only working on smartphones and tablets, will only work while using Iridium satellite airtime. XGate allows you to use any internet connection you may have, saving time and money.
Regardless of whether you use XGate or Iridium Mail & Web, you have the flexibility to use the compression email program that works best for you, all in tandem with Optimizer's world-class firewall.
50% Off Optimizer?
Here's how it works: you purchase RedPort Optimizer for full retail price and then send us back your AxcessPoint device. When we receive your AxcessPoint (along with this form) we will refund $75 back to the credit card you used to purchase Optimizer. (If you purchased Optimizer from another certified RedPort dealer, please contact them for instructions).
That's it! Easy peasy.
This promotion isn't going to last long, so make sure to upgrade now.
XGate satellite email service was named by Global Telesat Communications as one of the best apps for satellite communications.
XGate is state-of-the-art data compression software that delivers email, weather, web, and social media - right over your satellite phone. XGate is carrier-independent which means that you can use it with any satellite carrier using an IP-based satellite device (ie: the vast majority of them).
Global Telesat Communications said this about XGate:
"XGate is the easy way to access email through a satellite connection. The app compresses the data sent and received offering up to 85% savings on satellite airtime expenses. It also blocks out other unnecessary data use by the phone to avoid a large bill at the end of your trip!"
XGate is the leading independent satellite data service with thousands of people all over the world currently using XGate to keep connected over satellite.
Although Global Telesat Communications specifically mentions the iOS and Android versions of XGate, XGate is also available for PC and Mac. Once you have an XGate account you can use XGate on any device you have - no need to pay more to use different or multiple devices.

Vessel tracking is a huge priority in the marine world. Whether you’re a single sailor who wants to make sure his family can follow his route or a large fleet operator needing real-time position reports from your entire fleet, satellite GPS vessel tracking is integral to knowing where you - and your assets - are in the world.
There are three satellite GPS trackers that Global Marine Networks offers. Each of these units comes in a marinized, extremely hardy dome with water resistance up to 1 meter. They are mounted on standard threaded 1" antenna mounts although you will need to purchase the antenna mounts separately from a marine supply store.
All prices quoted here are up to date as of publication, but please check with us to make sure that prices have not been changed.
XTracker IR (Iridium) is a robust, dependable and extremely compact tracking device that sends out GPS position reports at pre-programmed intervals from anywhere in the world using proven Iridium satellite technology. Position reports contain date, time, latitude, longitude, and average course and speed over the ground. GPS position reports are recorded, transmitted, and posted on the web in 20 seconds, on average. XTracker’s modest power requirements make it ideal for remote locations where solar panels or batteries are the only source of electricity.
Because the XTracker IR operates on the Iridium satellite network, this tracker offers truly global pole-to-pole coverage.
Learn more about the XTracker IR here.
Get a quote for XTracker IR by contacting us here.
This tracker only works if there is a satellite broadband unit on board (VSAT, Fleetbroadband, Iridium Pilot, BGAN, Thuraya IP, and others) and provides position reports from anywhere on the planet. Unit can be connected to a long-life battery to keep the unit self-contained. Because the XTracker BR routes the position reports through your satellite broadband device, the frequency of the position reports can be whatever you want. Hourly? Sure. Every 10 minutes? No problem. Every 30 seconds? Done.
There is no additional charge for XTracker services for increased frequency, although you may incur additional charges on your satellite airtime bill for the airtime required to send the GPS pings.
Learn more about the XTracker BR here.

The RedPort XTracker GS allows you to track your assets and vessels anywhere within the expansive Globalstar Simplex coverage area without even relying on powering cables (although you can power over Ethernet, as well). Tracking can be set to every 5, 10, 30, or 60 minutes. Faster tracking is available (every 2.5 minutes), but it increases the monthly price. The tracking duration on these units has to be set on the tracker itself. It cannot be changed remotely.
Depending on the type of battery being used, the XTracker GS can last as long as 10 years without changing the battery or needing any kind of upkeep.
Learn more about the XTracker GS here.

How The GPS Vessel Tracking Works
Tracking for all units is provided through RedPort Tracking and consists of a detailed, robust online tracking interface that provides:
- Real-time Position and Tracking
- Longitude and latitude info
- Emergency alarm/ SOS/Movement alarm/ Overspeed alarm/ Border crossing alert.
- Geo-fence alarm
- Course and Speed (on web-based tracking site)
- Web-based tracking or mobile-phone-based tracking
- Central Monitoring system (web-base)
- History of tracking movements
- Ability to track hundreds of vessels or assets on one web-based monitoring system
Tracking is a monthly charge that encompasses the airtime required to send the satellite pings as well as a small fee for the dedicated web-portal and continuing tracking services.
We recommend going to tracking.redportglobal.com and clicking on the "Live Demo" option. This will give you a view of how the web interface works and what information can be derived from it.

We often get asked what is the most affordable option for satellite internet while at sea. As the satellite industry matures, more and more options are becoming available for internet connectivity on your boat and some of them can be very affordable. The options we've detailed here are intended for single users or small crew situations. (For large satellite internet options at sea, please contact us).
Satellite internet is still more expensive than any land-based internet you will find. How affordable (or not) it can be depends almost exclusively on how you use it.
Low-data usage (low cost)
Downloading weather files
Very small webpages (like NOAA, etc)
Note: if this is the kind of data you'll exclusively be doing, you will also be very well-served by a handheld satellite phone, as most of them can do this for you for a much smaller up front hardware cost. Popular options are the Iridium 9555, Iridium GO!, and RedPort Aurora.
High-data usage (higher costs)
Web-browsing, especially without compression
Any kind of streaming service (Youtube, Skype, Spotify, etc)
Certain VoIP services
Large and frequent file downloads
Satellite Terminals for Marine Satellite Internet
Now that we know what kind of internet activities will most affect your satellite airtime bill, let's talk about the equipment.
The Iridium Pilot is a fixed installation antenna that provides broadband capability. It is one of the least-expensive hardware options for marine satellite internet. Although it runs slow by land speeds (up to 128kbps - about twice the speed of dial-up) it is significantly faster than a handheld satellite phone (which runs at 2.4 kbps - 25 times slower than dial-up).
Because of this and other operational features of the unit, doing basic activities like email, weather, and voice calling becomes incredibly inexpensive. Downloading a GRIB file over a handheld satellite phone will cost somewhere around $2.15 in airtime. Downloading the same GRIB file over the Pilot would cost about 2 cents in airtime. While the upfront costs of the unit are more than a handheld, the ongoing costs are significantly less. Adding in the ability to web-browse (which, while expensive and slow, is possible and a very nice feature to have in an emergency!) means that you get a much higher quality of service than with a handheld satellite phone.
Hardware cost: $4,793 for the Iridium Pilot Savings Bundle
Airtime cost: From as low as $39 a month, with seasonal contracts available.
Estimated low-usage cost: Around $50 - $100 a month will cover you for email, downloading weather GRIB files, and doing emergency web-browsing.
Estimated high-usage cost: Committing to bundle with 1,000 MB per month will cost you just over $1,000 a month, with per-MB overage from $0.56 each.
Coverage: Worldwide, pole-to-pole
More info: we have a great (free!) guide to affordable satellite broadband that specifically looks at usage cases for the Iridium Pilot. You can check that out here.
FleetBroadband is one of the oldest marine satellite broadband options and certainly one of the most reliable. FleetBroadband comes in 3 different terminals: the 150, 250, and 500. Each terminal reflects the max download speed of the unit (the 150 goes up to 150 kbps). FleetBroadband works most places on the planet, provides smooth connectivity for downloads, and remains a popular choice for everyone from cruisers to commercial vessels.
Hardware cost: Around $6,000 for a Sailor 150, around $11,000 for a Sailor 250, and around $16,000 for a Sailor 500.
Airtime cost: While prepaid options are available, be sure to read the fine print. We recommend a postpaid plan. These start at $106 a month (includes 5 MB of data).
Estimated low-usage cost: Around $100 a month will cover you for email, downloading weather GRIB files, and doing emergency web-browsing.
Estimated high-usage cost: FleetBroadband postpaid options for high usage jump from 200 MB per month to 2 GB (with nothing in-between). 200 MB per month will cost you around $1,000 and 2 GB per month will cost you around $2,000.
Coverage: Excellent coverage up to 70 degrees latitude. For worldwide coverage, consider adding an Iridium Pilot as backup.
Inmarsat Fleet One
Inmarsat Fleet One is the newest satellite broadband option from Inmarsat. It is basically a lean version of a FleetBroadband 150. It runs at a max speed of 100 kbps and offers very inexpensive airtime options...with a catch. Inmarsat has created a special coverage map for the Fleet One. If you're within the "home zone" you get fantastic airtime rates of around $6 a MB. But if you go outside of the home zone you get dinged at $33 a MB.
Hardware cost: $3,295 for the AddValue Fleet One and $4,154 for the Sailor Fleet One.
Airtime cost: Prepaid and postpaid available. For $60 a month you get 10 MB a month within the home zone.
Estimated low-usage cost: Around $60 a month will cover you for email, downloading weather GRIB files, and doing limited web-browsing.
Estimated high-usage cost: Hard to calculate. There isn't a graduated scale for Fleet One airtime so usage as high as 1,000 MB a month would cost you around $5,800 (for home zone) - not a great solution. If you plan on doing high data usage, consider a different system.
Coverage: Excellent coverage up to 70 degrees latitude. For worldwide coverage, consider adding an Iridium Pilot as backup.
The KVH Mini-VSAT, more than any other broadband unit available for individual users, offers the fastest, cheapest airtime. With data speeds up to 2 mbps (around what you would get on 3G on your cellphone), you can quickly and easily access the web. There are three KVH systems: the V3, the V7, and the V11. The V3 is the least expensive at around $13,000 and the most popular with individual sailors.
KVH airtime is where the system really shines. Starting at $49 a month, KVH overage per MB is only $0.99 to $1.99.
Hardware cost: Around $13,00 for the V3 (although contact us, we might be able to make you deal), around $30,000 for the V7, and around $60,000 for the V11.
Airtime cost: Postpaid airtime starts at $49 per month. (For the V7 and the V11, unlimited plans are available starting at $995 per month).
Estimated low-usage cost: $49 a month will easily cover you for email, downloading weather GRIB files, and light web-browsing.
Estimated high-usage cost: 1,000 MB a month costs $999 per month, with $0.99 per MB in overage.
Coverage: KVH has good coverage in the Northern hemisphere, but doesn't have good coverage in the Southern hemisphere. Many users use an Iridium Pilot as a backup if they plan on traveling outside of the KVH coverage area.
Please contact us for pricing on KVH equipment and airtime.

One of the nice perks of the Iridium Extreme satellite phone is that it has an integrated GPS. This means that you can do GPS tracking over the Iridium network, giving you coverage everywhere on the planet.
But how does it work? Does it consume your regular airtime? How much does it cost to do satellite GPS tracking with the Iridium Extreme?
How Does Tracking Work on the Iridium Extreme?
Tracking on the Iridium Extreme goes over a channel on the Iridium network called LBS. LBS (location based services) is different from the channel that sends voice, data, and SMS and is therefore charged separately, with its own distinct airtime pricing.
LBS is a proprietary subset of a type of satellite transmission protocol called SBD (short burst data). Both LBS and SBD can only send very small bits of data at a time - a max of 1000 bytes - so it’s limited to data transmission like location reports, which are extremely small in size.
Tracking on the Iridium Extreme can be set up to go out on regular intervals or to simply send out a position report every time the phone registers. Tracking on an regular schedule with the Iridium Extreme has the benefit of keeping friends and family back home updated at a routine progress, but means that your phone needs to be powered on and registered with the network the entire time.
If you set your tracking to go out whenever you register you’ll get much less frequent position reports, but you’ll conserve power and not spend as much in airtime.
Does Iridium Extreme Tracking Consume Regular Airtime?
No. Tracking on the Iridium Extreme will not consume your regular voice or data minutes. Airtime for Iridium Extreme tracking is completely separate and in addition to your prepaid or postpaid airtime for your phone.
Furthermore, you must have an active SIM card (with either prepaid or postpaid airtime) in order to also use the Iridium Extreme’s tracking feature.
Where Can I See My Satellite Position Reports?
When Iridium receives the position reports from your Iridium Extreme satellite phone, it can then send those position reports to a LBS-certified third-party provider to then show your position and history on a map. Global Marine Networks works with RedPort Tracking, an industry-leading tracking platform that consists of a detailed, robust online tracking interface that provides:
Real-time Position and Tracking
Longitude and latitude info
Emergency alarm/ SOS/Movement alarm/ Overspeed alarm/ Border crossing alert.
Course and Speed (on web-based tracking site)
Web-based tracking or mobile-phone-based tracking
Central Monitoring system (web-base)
History of tracking movements
Ability to track hundreds of vessels or assets on one web-based monitoring system
How Much Does Tracking on the Iridium Extreme Cost?
Basic tracking for the Iridium Extreme starts at $29.95 per month. This includes approximately 220 position reports per month (about 7 per day, or about once every 3 hours). The frequency of the position reports can increase, but each additional position report will incur an overage fee.
There is a one-time new account setup fee of $59 that goes towards the configuration of your web-based tracking account, setting up tracking on your Iridium phone, and making sure your phone is correctly relaying position reports.
Note: pricing good as of publication of this post. Please contact us for the most up-to-date pricing info for any of our products or services.

Over the years, XGate has teamed up with a number of third-party GRIB retrievers and viewers to help deliver GRIB weather files over satellite connections. Until now, all of these programs (WeatherNet, iNavX, Weather4D, WeatherTrack, etc) have been for Windows, Mac, or iOS.
But we’re happy to announce that there is a great new option for Android: SailGrib!
SailGrib is a GRIB retriever and viewer all in one. Using SailGrib in conjunction with XGate satellite email service will allow you to retrieve GRIB files through email using XGate and then view them right in SailGrib using their Android app.
SailGrib is a handy little app that goes beyond simple GRIB files. Here are a few of the features sailors find most useful:
SailGrib Over Satellite
We’ve already mentioned it, but we’ll do it again - using SailGrib with XGate means that you aren’t tied to land to get your weather files. Using leading-edge compression, XGate allows you to download your GRIB files over satellite connections that are very, very slow by land standards. XGate works with any IP-based satellite phone (which is the vast majority of them) so you can get your weather anywhere you can get satellite reception.
SailGrib "talks" to XGate directly by spooling the GRIB request to the XGate outgoing email queue (through SMTP).
Fully Featured Weather Info
The weather information that comes through with SailGrib is pretty extensive: colored wind barbs, isobars with low and high values highlighted, precipitation map (rain and snow), cloud cover map, air temperature map, significant wave height map, mean wave direction and period arrows, and CAPE map.
You can also loop through time, allowing you to see weather movement and make decisions based on mobile patterns.
SailGrib can retrieve worldwide oceanic and European tidal currents, making it a truly robust resource for weather information around the world.
You can see SailGrib in the Google Play store here.
SailGrib Weather Routing calculates the fastest sailing route to your destination with a powerful method based on the isochrones method. An isochrone is a curve representing the points that a sailboat can reach in a given time. This curve depends primarily on the forecasted wind and currents plus the boat speed for that wind. The boat speed is derived from polar curves that represent the speed of the boat for a given wind speed and angle. We optimize the route calculating all the effects of the current on your boat as long as a current GRIB file is loaded.
All the calculations are done directly on your device, so you don’t need to consume any satellite airtime to get your sailing route.
SailGrib WR Features
Once you get your GRIB files into SailGrib WR, you can create the route to your destination on a map as well as by adding waypoints along your route.
- Set parameters by hand or automatically to specifically calibrate your passage.
- Specify upwind and downwind speed limits for low and strong winds
- Specify a minimum upwind angle for comfort while cruising
- Specify a night efficiency loss
- For cruisers, use mixed routing: decide when to start the engine and specify your motoring speed.
- Create a KML file and a GPX file of the best route
- Create an Excel file of your roadbook
- Choose to display best route courses, isochrones, isochrone segments on the map
- Go through time and overlay the boat with the weather forecast.
You can see the SailGrib WR app in the Google Play store here.
