Cobham Satcom, ViaSat Unveil PTT System for Mobile Satellite Services Market

Cobham Satcom and ViaSat plan to jointly offer a push-to-talk (PTT) system for the mobile satellite services market, ViaSat said in a news release Thursday. The system will involve Explorer 122, a "ruggedized" vehicle-mounted IP satellite terminal, which will operate over ViaSat's L-band managed service network and goes with Cobham's Explorer PTT-II system. The joint ViaSat/Cobham PTT offering will use LightSquared's SkyTerra-1 satellite, ViaSat said.
