About
Calian’s 7m LEO Earth Station Antenna is designed for tracking fast-moving low-Earth orbit (LEO) and medium-Earth orbit (MEO) satellites including broadband constellation terminals and scientific missions. The system uses a dual-reflector Cassegrain optical design with an elevation-over-azimuth-with-tilt mount to accommodate the high angular slew rates required for LEO tracking. The aluminum main reflector achieves surface accuracy below 0.008 inch RMS and the carbon fibre composite sub-reflector achieves below 0.002 inch RMS. Supported bands include C, Ka, Ku, S, and X. The adaptable antenna interface accepts de-icing, environmentally controlled hub, and adjustable polarization options. Full remote M&C is provided via Ethernet with multiple tracking modes. Calian has supplied 7m LEO earth station systems for government, commercial, and scientific satellite tracking programs.
