Based on the analysis of error characteristics and performance effect of the mostly used crystal oscillator, a method to simulate the frequency error of crystal oscillator is proposed. The major idea is to determine the Allan variance parameter of each main stochastic error component at the given sampling interval at first, then to deduct a set of corresponding frequency error series and superpose them together.

It is convenient for this model to build error equation and distinctly process the horizontal component and height component of GPS network.

此模型既便于误差方程的建立，又便于将已知数据的平面部分和高程部分分别进行处理。

Error Analysis of UGPS Error sources of UGPS include GPS observation error, attitude error, baseline network strength, sound velocity error, time measuring error.

系统的误差分析实现水下的精密定位，需要分析影响系统定位的各种因素。
