U.S. military to test Isotropic Systems antennas with SES satellites

SAN FRANCISCO – The U.S. Army plans to evaluate the performance of Isotropic Systems optical beam-forming antennas for sending communications through the SES satellites in geostationary and medium Earth orbit, under a contract of undisclosed value announced Sept. 24.

The contract was awarded by the U.S. Air Force Research Laboratory to SES Government Solutions of Reston, Virginia, a subsidiary of Luxembourg-based satellite fleet operator SES, and to Isotropic Systems, a firm based in Reading, United Kingdom, with a U.S. business unit in Reston, Virginia.

The U.S. Army evaluation is the first contract award for Isotropic Systems in its work with SES Government Solutions.
