利用DORIS相位数据的Jason-2卫星精密定轨

Jason-2 Precise Orbit Determination Using DORIS RINEX Phase Data

  • 摘要: 主要研究了DORIS系统RINEX观测值模型的建立及其主要误差——星载接收机钟差的改正方法,在此基础上实现了基于DORIS系统RINEX相位观测值数据的Jason-2卫星精密轨道确定。研究表明,利用拟合接收机钟差和利用RINEX频偏数据这两种钟差改正方法,基于RINEX相位观测值的Jason-2卫星精密定轨均能达到径向1cm量级的精度;而拟合接收机钟差改正能同时削弱接收机钟的高阶振荡误差,可以获得更高的定轨精度。

     

    Abstract: The new DORIS observations in RINEX format are now available with dual fre-quency phase and pseudo-range measurements. Due to shorter distribution latency with re-spect to the older MVR data in doris2.2format, this RINEX DORIS data can be widely used in LEO medium orbit determination. With analyzing the phase observation equation, this pa-per has proposed two different methods to correct the main receiver clock error, thus reali-zing the Jason-2POD based on DORIS phase data. The research shows that 1cm radial orbit precision can be achieved by using fitted receiver clock offset correction or frequency offset correction. And by weakening the high-order receiver clock error, applying the fitted clock offset correction can further improve the orbit precision.
