摘要

GPS被越来越多地装载在用于遥感、气象和海洋测高等应用的低轨卫星上进行精密定轨

低轨卫星星载GPS精密定轨的基本观测量为载波相位观测值

针对低轨卫星星载GPS的特点

给出了一种适合于星载GPS载波相位相对定轨的模糊度解算方法

及模糊度解算准确程度的检验方法。该方法应用于TOPEX/PO SEIDON卫星星载GPS实测数据

可得到分米级的定轨精度

Abstract

More and more GPS receivers are onboard low-orbit sat ellites for orbit determination

which can be applied to remote sensing

meteoro logy and sea surface altitude determination. The method of ambiguity resolution for relative orbit determination with carrier phase is proposed. Some criteria a re developed to identify correct ambiguities. With the method

the accuracy of c a rrier phase-based relative orbit determination may attain the order of a few de cimeter from the results calculated by using data collected from GPS/DR onboard TOPEX/POSEIDON.
