CAMSAT has announced the launch of its CAS-4A and CAS-4B linear transponder payloads. These payloads piggyback on the OVS-1A and OVS-1B optical remote sensing satellites, which were launched along with the hard X-ray modulation telescope (HXMT) satellite aboard a CZ-4B rocket from Jiuquan Satellite Launch Center at 03:00 UTC on June 15, 2017. Both satellites are in a 43 degree inclination orbit with an apogee of 524 km. Keplerian elements are not yet available at the time of this writing. This article will be updated with Keplerian element information when available.
Both satellites carry 20 kHz U/v linear transponders as well as CW beacons and a digital telemetry downlink. Frequency information is as follows:
| CAS-4A – U/v Inverting Analog SSB/CW | |||
| Uplink LSB | 435.210 MHz | through | 435.230 MHz |
| Downlink USB | 145.880 MHz | through | 145.860 MHz |
| CW Beacon 145.855 MHz. Digital Telemetry 145.835 MHz 4.8kbps GMSK | |||
| CAS-4B – U/v Inverting Analog SSB/CW | |||
| Uplink LSB | 435.270 MHz | through | 435.290 MHz |
| Downlink USB | 145.935 MHz | through | 145.915 MHz |
| CW Beacon 145.910 MHz. Digital Telemetry 145.890 MHz 4.8 kbps GMSK | |||
