SLR资料精密测定GLONASS卫星轨道
GLONASS Orbit Determination by Using SLR Data
-
摘要: 将SLR资料计算的轨道与CODE轨道进行了比较,并将比较结果转换到RTN坐标系中。通过比较分析发现,两种轨道差值在轨道径向、法向和沿轨方向的精度分别优于10cm、50cm和45cm;SLR和微波资料确定的GLONASS卫星轨道在径向存在系统误差,该系统误差随卫星轨道面的不同而不同。Abstract: The orbits of the GLONASS Satellites are determined by using the SLR data observed from March 28 to April 24,1999.The seven-day orbital arcs for the GLONASS satellites are computed.The results with the orbits of satellites computed by CODE are compared.The systematic error between SLR orbits and radiometric orbits of GLONASS satellites is confirmed.
