A key component of any BGAN user terminal

The BGAN Protocol Stack (BPS) is the software core module to several BGAN user terminal manufacturers including: Addvalue Technologies, Japan Radio Co., Honeywell and Hughes. The BGAN Protocol Stack is a combined UMTS Non-Access Stratum stack on top of the proprietary Inmarsat Access Stratum. Together with physical layer software and application layer it forms the required software for a BGAN user terminal.


The BGAN Protocol Stack is a core component in the Inmarsat User Terminal Reference Stack which guarantees that the BGAN Protocol Stack is compliant to Inmarsat System Definition Manual (SDM). It is thoroughly tested using Inmarsat Mandatory Test Requirements and over-the-air by BGAN satellite. Further, exhaustive testing is also done with Gatehouse Satcom’s own automatic test suite which has been refined over many years. It is possible to integrate the BGAN Protocol Stack with any physical layer, whether developed by the customer or offered by Gatehouse Satcom.

Reduce risks

If you are developing a new BGAN user terminal, the BGAN Protocol Stack is a must. It reduces costs and risks significantly as the product is already proven. This means that you can fully focus on building the terminals and the specific feature set for the terminals and bringing them to market.

Ensure testability

The re-usability, portability and testability of the BGAN Protocol Stack is demonstrated through several different customer implementations. In fact, it is implemented in more than 40 different products. You can feel safe knowing that the product is applicable to your needs.

Mature software

More than 120,000 terminals have been licensed with the Gatehouse Protocol Stack. Using the mature BGAN Protocol Stack will release resources to focus on the important features targeting your customers’ needs and hereby ensure your differentiation in the market.

“Hughes San Diego has worked with Gatehouse from when they first got started in the satellite communications business many years ago and our continuous cooperation persists till this day with great success. Gatehouse has provided solid products, technical support and expertise to Hughes for the duration of this period and we look forward to continued collaboration in the years to come.”

Graham Avis, Vice President and General Manager, Hughes San Diego


Technology partner to Inmarsat

Gatehouse has a long-term cooperation and partnership with Inmarsat and has supplied the complete BGAN Protocol Stack (including UMTS NAS) as a reference implementation used to validate Inmarsat Mandatory Test Requirement scripts and associated type approval equipment.
