基于双差观测序列曲线拟合实现GPS静态定位基线实时解算

对于ＧＰＳ静态差分定位的实时算法而言，能否实时地解决观测数据的存储、卫星失锁、载波相位周跳、多径效应以及计算速度等问题是保证基线的实时解算和定位成功率的重要因素。本文利用载波相位双差观测时间序列可用直线或高次曲线进行很好拟合的特性，设计了一种静态定位的实时算法，能解决上述实时定位中的特殊问题。

REAL-TIME SOLVE GPS STATIC BASELINE BY FITTING DOUBLE-DIFFERENCE SERIES WITH SMOOTH CURVE

For real time DGPS static positioning scheme, it is very important to resolve those problems such as the observation data storage, satellite lost lock, cycle slip, multi path and calculation speed in real time. In this paper, a new scheme is developed to overcome those problems by fitting the double difference series with smooth curve. The new scheme has a flexible and reliable construction, and can be applied to develop practical real time DGPS static positioning software.
