| Headline Details: A 30kg spacecraft 499x461x284 mm. CRAC-01 is a small satellite designed by Engineering Team of Experimental School attached to the Chinese Academy of Sciences, Reger Technology . The target is to have the amateur radio in the space and educational program with middle school students. The space amateur radio station will provide VHF telemetry downlink. UHF telecommand uplink. V/U NBFM transponder. X band image data downlink experiment. The X band image data downlink will be controlled through UHF public telecommand channel. The educational mission includes: Fruit fly cartridge for the biology experiment in the space; The photographic captured on the orbit. The CRAC-01 will use SDR based transceiver to provide communication and experiment resources to radio amateurs, including a V/U NBFM transponder, a VHF telemetry downlink and a X-band image downlink for experimentation. The satellite will also provide an open telecommand for radio amateurs sending commands to control the satellite and obtaining the orbit camera images. Proposing a U/V FM transponder and VHF telemetry downlink using 9k6 GMSK and image download on X Band using 10M or 1M QPSK. Planning a Q4 2023 Galactic Energy launch from Jiuquan into a 500km circular polar orbit. Link budgets are here https://bi1rg.github.io/posts/crac-01/ and more info here https://bi1rg.github.io **FM transponder downlink on 145.980 MHz, TLM downlink on 145.995, voice and image downlink on 10455.00 MHz have been coordinated together with the FM transponder uplink on 435.900 MHz.** **Now planning a launch from Jiuquan in Q4 2024 into a 520 km polar orbit** | ||||
