GPS伪距动态定位计算模型

Calculation Model for GPS Pseudorange Positioning

介绍ＧＰＳ伪距动态定位的计算模型，包括一般的差分定位模型、卡尔曼滤波定位模型、由几个历元的观测值同时求位置和速度的模型、由多个历元的观测值求轨迹的模型、以高斯平面坐标和高程为参数的模型和固定高程的定位模型．最后讨论了定位粗差的控制方法．

In this Paper, GPS kinematic positioning models with pseudorange are introduced.These positioning modelsinclude genelal differential positioning model, Kalman filter model, calculating position and velocity simultaneouslywith observations of past epochs, trace determination with past observations, using Gauss plane coordinates as parame- ters, and height fixing. Also introduced is controlling of blunders.
