Le Bourget. 20 June 2017. In May 2017, Inmarsat and Thales informed that they had executed a series of tests that successfully demonstrated communications using Thales’ System 21 on Inmarsat’s Global Xpress (GX) high-capacity steerable antennas.

These tests illustrate the ability of Thales’s System 21 modem to support resilient, protected and secure, high-data-rate connectivity for mission-critical military and government users.
