About
The Ground Antenna System 2 is specifically designed to function as an integral part of satellite communications earth stations, facilitating the transmission of X-band signals. This transmitting two-mirror antenna system is built upon the Cassegrain design, incorporating a 2.5-meter reflector with an irradiating system and a counter-reflector. It also includes a slewing ring equipped with electromechanical drives for precise pointing. The system does not include radio receivers or radio transmitting devices, focusing solely on the antenna and its pointing mechanisms. Released in 2011, it boasts a guaranteed service life of 15 years. The estimated production and delivery time is 9 months, and the product offers the possibility of adaptation to meet specific customer requirements.
