Profitable check for electronically managed antenna through International Xpress

Gilat Satellite Networks, a satellite networking technology and services company, announced that a test of its Electronically Controlled Antenna (ESA) over Inmarsat’s Global Xpress (GX) network was successful. The open architecture ESA has been integrated with Inmarsat’s G-MODMAN technology, which supports the implementation of Global Xpress terminals on aerospace platforms.

The live demonstration of an ESA terminal was carried out on an operational GX satellite from Inmarsat. The test was carried out on the Inmarsat-5 F1 satellite at 62.6 degrees East. Gilat’s self-aligning antenna automatically logs into the GX network and supports bi-directional real-time communication in both fixed and dynamic antenna positioning modes. Beam steering under the changing elevation and tilt angles was performed while the power spectral density (PSD) threshold was managed to minimize interference with neighboring satellites in accordance with relevant regulations.

Gilat says the successful test shows its ESA’s readiness for commercial use.

“The seamless integration of our G-MODMAN with Gilat’s antenna control system via standard open interfaces is an important factor in demonstrating the ability to support Electronic Steered Array technology in Inmarsat’s global satellite network,” said Jerome Soumagne, VP Networks chief engineer Inmarsat.
