GPS (Global Positioning System)在新一代卫星载荷中采用了大量新技术,首颗卫星成功发射后,官方尚未系统公布各导航信号的调制方式、复用方法等关键信息,因而其在轨测试阶段的空间信号质量评估具有重要的意义.该文选择地面接收功率、功率分配、相位关系、调制特性和测距性能等评估参数,深入分析了GPS III卫星L1频点空间信号质量,剖析了该卫星上多种新技术的信号特征.论文成果对其它GNSS(Global Navigation Satellite System)卫星载荷设计及信号体制设计等方面具有重要的参考意义.
GPS III (Global Positioning System) satellites have adopted a large number of new technologies in payload. After the successful launch of the first satellite
the official has not yet published effective information such as the modulation method of each navigation signal and multiplexing method. Therefore
it is meaningful to evaluate the signal-in-space quality. In this paper
the evaluation parameters such as ground receiving power
signal component power distribution
phase relationship
modulation characteristics and ranging biases were selected. Signal-in-space quality of GPS III satellite L1 frequency was analyzed comprehensively
and the characteristics of various new technologies adopted by the satellite were analyzed. The results of this paper have important technical reference value for other GNSS (Global Navigation Satellite System) satellite payload design and signal system design.
