卫星厘米级定轨的实施建议

对我国实现卫星厘米级定轨的技术途径 ,提出了下列建议 :利用我国在国外的卫星观测站和在国内的 IGS跟踪站 ,建立 GPS国际基准观测网 ,进行星载 GPS双频动态载波相位测量定轨 ;注重大气阻力摄动对低轨卫星定轨的精度损失 ,不仅要安装性能优良的星载 GPS双频接收机 ,而且要装备卫星加速度计 ;采用星载 GPS信号接收机 /激光后向反射镜阵列协同定轨法 ,确保卫星定轨测量的径向误差达到厘米级

Operational Recommendations Acquiring Centimeter Accuracy of Satellite Orbit Determinations

According to our engineering practices on GPS kinematical carrier phase measurements and Satellite Laser Ranging the following recommendations are proposed to acquire centimeter level orbit determinations for Chinese LEO satellites: To establish an international GPS reference observation network by means of satellite tracking stations at abroad and IGS tracking stations at home in order to perform satellite-borne DGPS orbit determinations; To reduce especially an influence of atmospheric drag perturbation on the accuracy of orbit determinations for LEO satellites,using that not only to exploit a satellite-borne GPS dual frequency receiver of excellent performance,but also to exploit a satellite-borne accelerometer; To make use of a synergistic orbit determinations with satellite-borne GPS surveying and Satellite Laser Ranging,so as to ensure the centimeter level radial accuracy.
