Key highlights
The AAC Clyde Space Quasar-WSANT is our next-generation telecommand, telemetry, and payload-data S-band antenna for SmallSats and CubeSats. Built on proven augmented patch antenna technology with extensive flight heritage, it delivers robust wideband performance across both ITU-R receive and transmit bands in a single, compact unit.
Part of the Quasar product family, WSANT integrates seamlessly with the Quasar-STRX SDR transceiver to provide a complete end-to-end TMTC solution.
The compact, wideband antenna removes the need for two separate antennas for up- and downlink paths and the diplexer option enables improved band-isolation.
This solution is compatible with Bright Ascension Flight Software suite used on AAC Clyde Space spacecraft.
Applications
CubeSat, smallsat, nanosatellite missions.
Key features
- One antenna, full coverage – spans the complete ITU-R S-band (2025–2290 MHz)
