基于载噪比及参数先验信息的抗差模型

Robust Model Based on C/No and Priori-information of Parameters

摘要: 结合GPS应用的特点,建立了一种综合载噪比(C/No)及参数先验信息的抗差模型。试验结果表明该模型具有更高的抗差性能,从而能更有效地削弱GPS观测量中各种误差的影响。

Abstract: Based on GPS application,a new stochastic model based on the combination of C/No and priori-information of parameters is proposed.The results show that the new model is more reliable and can mitigate the errors in the GPS observations effectively.
