GateHouse Telecom has developed an emulator that will enable application providers to test their concepts over Inmarsat’s Global Xpress network. This will allow applications to be developed for maritime industries to improve the performance, efficiency and quality of VSAT.
Inmarsat approved the Global Xpress Link Emulator after performance testing in April this year. It can now be used by Inmarsat partners to test Global Xpress applications, including those for Fleet Xpress, off-air without the use of a terminal.
The emulator simulates a real satellite connection and terminal. This means service providers and application developers can use the emulator at any time in a laboratory for development and testing.
GateHouse’s link emulator can also be used by service partners to demonstrate their Global Xpress solutions. It can also be used for troubleshooting problems with applications and connectivity without calling on direct support from Inmarsat.
Inmarsat has recommended that its partners use an emulator such as GateHouse’s to test Global Xpress solutions effectively. “Applications and solutions should be thoroughly tested in any number of network scenarios and in different bandwidth conditions before being introduced to the market,” said Inmarsat director of Global Xpress simulation and modelling Olaf Rostbakken.
He added: “GateHouse’s Global Xpress Link Emulator tool allows application developers and value added manufacturers to do part of this in a controlled environment and can reduce the cost of testing in the process.”
The link emulator includes the ability to test multiple channels, simulate possible signal degradation scenarios caused by storms or blockage, simulate traffic congestion scenarios, and optimise for minimum airtime usage.
