摘　　要：结合多频伪距/载波相位组合的周跳探测与修复原理,给出了优化的多频相位组合周跳检验量模型的确定方法。以组合观测值周跳的最小估计方差为衡量标准,确定(0,1,-1)、(-3,1,3)、(1,-7,6)为优化组合模型;用VB编写了多频组合周跳探测程序,并结合实例与其他模型进行了对比分析。结果表明,该模型的周跳探测精度优于其他模型,且能准确探测出各频率的周跳,探测效果明显,结果可靠。Based on the principle of cycle slip detection and repairing of the multi-frequency pseudo range/carrier phase,this paper put up an optimal determining method for cycle slip detection model of the multi-frequency phase combination.Taking the minimum observation cycle slip estimation variance as the standard,the paper determined the(0,1,1),(-3,1,3),(1,7,6)for the optimal portfolio model.And then,the paper used VB to write the procedure of multi-frequency combination of cycle slip detection and repairing,and contrasted with other models.The results show that the detection accuracy of this model is superior to other models,and it can accurately detect any frequency.The cycle slip detection effect is obvious,and the detection results are reliable.
