[Satellite Today 07-30-09] ViaSat Enerdyne has released its EnerLinks 3 Autotracking Antenna System (ETAS), a complete ground station for video and ISR data links, which uses the EnerLinks 3 ground modem transceiver, the company announced July 29.
    The ETAS system includes: a 24-inch parabolic antenna, an omni-directional antenna, a radio interface module, a gimbal to point the antenna, a rugged tripod to support the equipment, and two transit cases for the antenna assembly and electronics.
    ViaSat said that ETAS enables the EnerLinks 3 to deliver a downlink line-of-sight range of at least 75 nautical miles at 11 megabits per second (Mbps) and more than 100 nautical miles range at 5 Mbps, operating at L-, S-, or C-band frequencies. The system can automate the uplink and downlink between both the omni-directional and ground station antenna.
