摘　　要：针对GPS和北斗二代的测量原始数据,研究了卫星导航定位问题,给出了一种基于测元融合的定位算法。通过对卫星信号模拟器数据的融合解算,得出了目标的定位结果,并与模拟器真值数据做比较分析。结果表明:融合算法正确有效,该方法可以在测量的相关领域中应用。The problem of satellite navigation is studied. Based on raw measurement data of GPS and Beidou-2, a fusion positioning algorithm of measurement elements is proposed. By fusion resolution of the data from satellite signal simulator, the positioning parameters of target is presented, and is compared and analyzed with the true value of simulator. The results show that the fusion positioning algorithm is correct and effective. And the method has been demonstrated successfully in measurement field.
