‰ NOW 18 WPM transition file follows‰ Quick on the heels of the September 19 launch of nine satellites carrying Amateur Radio transponders comes word that three more satellites were launched on September 25 from the Jiuquan Satellite Launch Center in Inner Mongolias Gobi Desert. The CubeSats, identified as Tianwang 1A, aka TW 1A SECM 1, Tianwang 1B, aka TW 1B NJUST 2, and Tianwang 1C, aka TW 1C NJFA 1, were developed by students at the Nanjing University of Aeronautics and Astronautics in collaboration with the Shanghai Engineering Center for Microsatellites. TW 1A and TW 1B are 2 U CubeSats, while TW 1C is a 3U CubeSat. The missions main goal is to experiment with software defined radio technology in space. The Amateur Radio payloads, which do not include any transponders, will serve to exchange telemetry, tracking, and command information with the ground control station. Telemetry data will be made public, so that radio amateurs around the world may track and monitor the health of the satellites. Other payloads include a video camera, along with receivers for dual band GPS/BeiDou, Maritime Automatic Identification System, and Aeronautical Automatic Dependent Surveillance Broadcast. Using MEMS based cold gas micropropulsion, it is planned to demonstrate formation flying by two of the CubeSats along with inter satellite communication using GAMALINK 2.4 GHz spread spectrum technology from Portugal. According to Michael Chen, BD5RV, of CAMSAT, the satellites have downlinks in the 435 to 438 MHz Amateur Satellite Service allocation. TW 1A transmits on 435.645 MHz, using GMSK 4800/9600 baud with a 10 second transmit interval, TW 1B on 437.645 MHz, using GMSK 4800/9600 baud with a 20 second transmit interval, and TW 1C on 435.645 MHz, using GMSK 4800/9600 baud with a 10 second transmit interval. Note that TW 1A and 1C use the same frequency. The satellites also may have downlink frequencies in the VHF range. TW 1A is object 40928, 2015 051D. TW 1B is object 40927, 2015 051C, and TW 1C is object 40926, 2015 051B. On the same launch was the technology demonstration satellite Pujian 1, which includes WiFi technology for intra satellite communication. Trevor, M5AKA, said its believes that Beijing plans another launch of Amateur Radio payload satellites on October 5. ‰ END OF 18 WPM transition file ƒ
