Vietnamese CubeSat under developmentNews has been received from Vu Trong Thu, XV9AA, in Hanoi of a Vietnamese Amateur Radio 2U CubeSat under development. Thu wrote, "We hope to complete the F-1 satellite by the end of 2010 and launch it to Sun-synchronous, 98 deg inclination LEO. "At the moment we are negotiating with several launch providers to find a way into orbit but the high launch cost is really an issue. If we can solve the budget issue, we'll be ready to launch our cubesat in 2011." The satellite carries several low-resolution cameras to take photos of the Earth along with temperature and magnetic sensors to study space environment. Some of the project goals for the F-1 satellite include: + Students to learn about aerospace engineering. The satellite will use amateur VHF and UHF frequencies. The IARU has coordinated at downlink frequency of 437.485 MHz to support a 1200 baud AX.25 telemetry link. The F-1 satellite will also transmit a beacon using a modulated Morse code audio signal on FM carrier when it is not in range of the earth station in Hanoi. In case of emergency, DTMF tones can be used to control the satellite to some extent. The satellite also carries a COTS transceiver (using UHF frequency) from Microhard Systems to experiment with higher data transmission speed. A breadboard model of the satellite has been built and the communication link has been tested at a range of 50km. The team is now working on the Engineering Model of the satellite and more tests are planned including shock, vibration and thermal tests.
