Abstract: Aiming at generic model of location precision is applied to only a sort of location system, its universal model of location precision is educed based on the class of location system(non-redundant system and redundant system). The location precision of non-redundant system is analyzed based on the error is separable. Aiming at the characteristic of redundant system, its universal models of the analysis of location precision in three-dimension space are educed according to the condition of Markov estimator. The two universal models is adapt to the analysis of location precision of different location systems. At last the veracities of the two universal models are validated through simulation and the contrast of data.

Key words: location, Geometric Dilution of Precision(GDOP), error separation, Markov estimation, redundant system, non-redundant system

摘要： 传统的定位精度分析模型只能分析一种定位系统，适用性较差。为此，将定位系统分为冗余系统和非冗余系统，基于误差可分离的思路推导非冗余系统的定位精度模型，利用马尔可夫组合估计条件推导冗余定位系统的定位精度模型。仿真实验结果验证了2种通用模型的准确性。
