摘要
Abstract
Based on the NJUST-1 CubeSat mission, the very high frequency/ultra high frequency ( VHF/UHF) satellite ground station is designed to realize the uplink and the downlink of the signal successfully. The characteristics of the CubeSat communication is analyzed,and the system scheme of the VHF/UHF band ground station based on the audio frequency shift keying ( AFSK ) modulation and the binary phase shift keying( BPSK) demodulation is proposed. The AFSK modulation is based on the hardware and the BPSK demodulation is based on the Costas loop. The practical test shows that the sensitivity of the BPSK demodulation is up to -120 dBm,and the signal of other CubeSats like QB50P1 and QB50P2 is demodulated successfully.关键词
