SB-SAT technology enables relay of data from LEO to GEO satellites – Intersatellite Data Relay Services (IDRS) for cost-efficient and real-time connectivity. Reduce time, cost and risk involved in development of an SB-SAT terminal with this proven SB-SAT protocol stack.
The Gatehouse SB-SAT protocol stack is an adaption of the market-proven BGAN Protocol Stack which has been deployed in more than 120,000 end-user terminals for land, maritime and aeronautical uses.
SB-SAT Protocol Stack is complemented with a test suite for efficient development and qualification. SB-SAT is based on the aeronautical terminal classes and provides additional features for use in low-earth orbit.
IP connectivity up to 492 Kbit/s
Antenna pointing
Beam handover and satellite switching
Predictive handover at spot-beam boundaries
Accurate return link burst timing based on orbit extrapolation
Predictive Doppler compensation
The Gatehouse SB-SAT Protocol Stack for Low-Earth Orbit (LEO) Satellites is a low risk alternative to a key component in development of an SB-SAT terminal, as it is based on the proven BGAN Protocol Stack which has more than 120.000 terminal licenses under its belt.
The SB-SAT Protocol Stack is a mobile device protocol stack for use on LEO Satellites, and in combination with Inmarsat’s I4 and I6 network of GEO-stationary satellites, it enables global and continuous connectivity to LEO satellites.
With the SB-SAT Protocol Stack, you efficiently reduce the uncertainty related to development of a new terminal, hereby saving you both time and expenses.
The protocol stack is fully conformance tested applying Inmarsat test requirements and is validated by full-orbit simulation using the Gatehouse BGAN Network Emulator. The capabilities of the emulator allow set-up of realistic orbits with full simulation of beam-to-beam handovers and satellite switches.
The maturity of the protocol stack combined with the availability of efficient test tools ensures optimal foundation for an efficient and smooth integration process.
