LilacSat-2 ( Chinese 紫丁香 二號 / 紫丁香 二号 , Pinyin Zǐdīngxiāng Èrhào ), also CAS-3H , is a Chinese experimental and training satellite and an amateur radio satellite . The satellite was built by a team of 15 students from the Harbin Institute of Technology (HIT) under the direction of Wei Mingchuan (魏明川, * 1991).
construction
LilacSat-2 carries four payloads:
- V / U amateur radio SDR platform. This platform can be used as linear transponder , FM - repeater or as APRS - Digipeater be configured. Furthermore, a CW beacon and a UHF - 9k6 - BPSK - telemetry - downlink connection are provided.
- SDR-based multiband receiver for receiving and decoding signals from AIS , ADS-B- like services.
- FPGA software test platform.
- Thermal camera
The satellite has a rod antenna for the 2 m band and a turnstile antenna for the 70 cm band.
mission
The satellite was launched on September 19, 2015 on a Langer March 6 launcher from the Taiyuan Cosmodrome in China together with 19 other satellites. On July 10, 2016, the SDR was configured by LilacSat-2 as a linear transponder and successfully tested. The satellite is active (as of August 2019).
Frequencies
The frequencies for the amateur radio payload with the callsign BJ1SI were coordinated by the International Amateur Radio Union . Deviating from this, an uplink area is used that is not in the satellite area:
- 144.3425 MHz - 144.3825 MHz uplink, USB
- 437.1800 MHz - 437.2200 MHz downlink, USB
- 437.200 MHz digital telemetry, 1k2 / 4k8 / 9k6 AFSK / GFSK
