CAS-2T is a Chinese amateur radio and technology testing satellite . CAS-2T and KS-1Q are two autonomous payloads that are permanently mounted on the upper stage of a Langer Marsch 11 (CZ-11) launcher .

CAS-2T is a 2U CubeSat built by secondary school students in Beijing 's Fengtai , Xicheng and Haidian neighborhoods . The KS-1Q payload was built by the Kechuang Aerospace Forum and is used to test assemblies for planned satellites. It consists, inter alia, of a sun sensor , a TT & C - transponder , an optical telemetry transmitter , an inertial measurement unit and a wide-angle camera .

mission

The CAS-2T and KS-1Q were launched on November 9, 2016, along with four other satellites, from the Jiuquan Cosmodrome in Inner Mongolia .

Reports from radio amateurs around the world about CAS-2T agree that the CW telemetry beacon has good signal strength but is also affected by fading . The system's FM transponder is not working properly. It responds well to uplink signals, but the modulation of the downlink signal is not clean. The rocket stage with the payloads was originally expected to be in orbit for only about 30 days before re-entering the Earth's atmosphere. The orbit reached at an altitude of about 1000 km × 500 km allows a lifespan of several years.

Frequencies

  • CW telemetry take: 435.710 MHz
  • FM transponder uplink: 145.925 MHz
  • FM transponder downlink: 435.615 MHz
