A New Approach for Carrier Ambiguity Resolution under Multipath Condition

摘要：

In radio navigation system working on medium- short wave band, serious multipath interference and atmosphere noise make the precision of code tracking loop decrease. In order to improve the positioning precision, carrier phase measurement is generally adopted, but carrier ambiguity resolution is a key problem. Based on the analysis of multipath error of code tracking loop, a carrier ambiguity resolution algorithm is proposed in this paper, which uses narrow code correlation space to improve the precision of code tracking loop and uses the changing trend of different correlation spaces to test and restore the carrier ambiguity. Theoretical analysis and experiment results show that the method can eliminate the carrier ambiguity effectively.
