| Abstract: | In order to resolve the carrier phase ambiguity in single epoch observations between the virtual reference station and rover user when the VRS technology is applied,a new carrier phase ambiguity resolution strategy is proposed.Firstly,a modified LAMBDA method is introduced to directly fix the wide-lane ambiguities.Secondly,a proposed linear combination model of L1 and L2 carrier phase is used to resolve one way L1 and L2 ambiguities.Some numerical tests are conducted and the test results indicate that the p... |
