摘要
讨论了GPS/GLONASS组合单点定位的数学模型和数学处理方法,分析了在GPS观测卫星数大于或小于4颗情况下组合单点定位的结果,实现了低精度要求下的导航定位。
The mathematic model and processing ways for GPS and GLONASS combined the single pointpositioning are discussed, then the result of the model is analyzed when the number of the GPS satellites viewed is more than four and when it is less than four, and navigation under the needs of low accuracy is realized.
