With the support of the CAS Priority Program on Space Science, from April 20 to 23, an experiment on data transmission over terrestrial and satellite links onboard the Hard X-Ray Modulation Telescope (HXMT) was successfully conducted at the Sanya Ground Station.
Organized by RADI, the experiment demonstrated the interface matching performance of HXMT, such as transmission/acquisition frequencies and spectra, modulation/demodulation, scrambling/descrambling, and coding/decoding.
As the first satellite of the CAS program, HXMT will be the best hard X-ray telescope in terms of sensibility and spatial resolution in all the known programs in the world. It will perform an all-sky hard X-ray survey, in which about 1,000 new hard X-ray sources will be discovered, and sensitive pointed observations of important cosmic X-ray sources including black holes and neutron stars. Its data will be received by three ground stations of RADI in Miyun, Kashgar, and Sanya.
