13M X-band Turning Head Antenna are applied for Telemetry,Tracking&Command/Remote sensing, Deep space missions/Geodesy, Radio astronomy,which is designed and manufactured by Antesky. It supplies continuous stroke, high speed and accelerated velocity, as well as high pointing accuracy/tracking accuracy, the antenna allow all visible operation for GEO Satellite and LEO Satellite; Another mission is to do the deep space exploration, single frequency band Tx/Rx, multi frequency band Tx/Rx, multi frequency receiving feed system, highest frequency band can be applied for ka-band.
Servo drive and tracking system can supply each operation modes, all antennas can equip reflector electric heating de-icing system, include integrating infrared heating rods on the antenna reflector. Antenna pedestal support/tower pedestal can be steel structure or reinforced concrete structure. Tower pedestal can be done as a hub equipment room which can supply electronic equipment.
Except the antenna system is supplied by Antesky, all transmitting/receiving electronic products can be customized by the customer; Antesky has a professional project management team to supply design, producing, transportation, installation, debug, and acceptance test, as well as after-sale maintenance and repair service; Antesky is an antenna system who provides turnkey services to the customers.
