摘要
分析研究了深空测控通信的特点,对频段提高、灵敏度提高、G/T值提高、EIRP提高、编码增益提高、定轨精度提高、极窄带锁相、低门限接收和调制/解调方式等主要技术问题进行了探讨.
This paper analyses the features of deep space tracking, telemetry, control and telecommunication (TrC&T) systems and discusses the main techniques to improve receiver sensitivity, frequency bands, G/T, EIRP, coding gain, orbit determination accuracy and narrow-band PLL and modulation/demodulation.
