BGAN Coverage Map
 
Ground Control's BGAN service is global with any BGAN plan we offer. The circular lines on the map show the "Look Angle" of the nearest Inmarsat BGAN satellite. For example, to connect from California, a BGAN terminal will need to point south-south-east and tilt up 45° degrees from the horizon, while a BGAN terminal in Nigeria will aim east-south-east and 60° degrees up. Most BGANs come with a small compass built into the terminal to help you point.

Any BGAN terminal will operate in any country within any of the three coverage areas above with any of Ground Control's BGAN service plans. Also, any BGAN terminal may move to any location and connect with any of the satellites without need to reconfigure the system or need to purchase any different service plan (ideal for world travelers).

I-4 MEAS - (online as of July 12, 2016)

New 4th Inmarsat satellite in 2016 - Fully opperational as of July 12, 2016
The new Inmarsat I-4 MEAS (Middle East and ASia) will the the 4th Inmarsat satellite that can be used by all BGAN terminals for connectivity. The MEAS satellite's primary objective is to provide more capacity to users in these regions.

The new I-4 MEAS satellite is outlined in red below.

please make sure your BGAN terminal has the latest firmware installed - BGAN Firmware


Satellite Access Stations and the Primary NOC
Inmarsat has 32 Satellite Access Stations (SAS) at strategic locations through the world that are all privately interconnected. The 6 primary SAS stations are located in New York, Hawaii, Hong Kong, Italy and Amsterdam. The Primary Network Operations Center (NOC) is located in London UK and performs the coordination of all network activities, monitoring and troubleshooting.

Excellent In Stormy Weather
Since a BGAN terminal uses the L-band for reception and transmission (the L-band has a very long wavelength), it is able penetrate through clouds and other atmospheric condition far better than large satellite dishes.

Can BGAN Be Used On A Ship or Boat?
Inmarsat does recommend using their FleetBroadband service for maritime connectivity, but many have sucessfully used BGAN terminals to connect over the years. We recommend the MCD-4800 that has its own power so the terminal is easily transported from vessel to vessel and can be used on land. For fixed terminals, we recommend the Explorer 510 or the Hughes 9202 BGAN terminals if motion is very limited and the vessel is traveling in a straight line.

Interesting Facts On BGAN I-4 Satellites and Coverage Area
Today there are three BGAN Satellites that give contiguous worldwide coverage. Each I-4 can generate 19 wide beams and more than 200 narrow spot beams. These can quickly be reconfigured and focused anywhere on Earth to provide extra capacity where needed. Information on Inmarsat Wide Beams and Narrow "Spot" Beams.

Some of the spacecraft's impressive features include:

  • The I-4 body - approaching the size of a double-decker bus at 7m x 2.9m x 2.3m
  • Solar arrays - approaching the width of a football pitch, with an immense wing span of 45 meters
  • Solar panels - combining conventional silicon with advanced gallium arsenide (GaAs) cells for optimum efficiency
  • Digital signal processor - controlling the antennas, beam forming and channel allocation
  • Reflector - 9 meters wide and designed to unfurl in orbit like a giant flower
  • Antennas - 120 helix elements combined in a single flexible array
  • Thrusters - both chemical and plasma ion for orbital station keeping

Prior to January 7, 2009, there were only two BGAN satellites that serviced the Americas and Europe/Africa regions (click here see old BGAN coverage map). With the successful activation of the third satellite on January 7th (which was activated over the Americas) the two existing BGAN satellites were repositioned to better global locations for full world-wide coverage. The first phase of repositioning completed on February 6th with new coverage region for Europe/Africa. The second and final phase happened on February 24, 2009 for the Asia Pacific regions.

Spot-Beams for Seamless Coverage

There are 228 Spot beams for each of the I-4 Inmarsat satellites.
