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。
Based on GPS No and priori-informatio more reliable and can mi application, a new stochastic model based on the combination of C/ n of parameters is proposed. The results show that the new model is tigate the errors in the GPS observations effectively.
