A method for performing integer ambiguity resolution in a global navigation satellite system is disclosed. A set of ambi gui ti es, which are associated wi th carri er phase measurements of at least some of the signals received from the satellites in an identified set of satellites, are identified (block 420 in Figure4A). I nteger ambiguities are estimated and a best candidate set and a second best candidate set of integer ambiguity values are determined (block 430). Upon determining that the best set of integerambiguity val ues f ai I to meet a discrimination test (block 440), each ambiguity for which integerambiguity values i n the best candi date set and second best candi date set fa I to meet predef i ned cri teria are removed from the set of ambiguities to produce a reduced set of ambiguities (block 450 in Figure 4B). The integer ambiguities in the reduced set of ambiguities are then resolved (block 468 in Figure 4C) and an output is generated in accordance with the resolved integerambiguities (block 470 in Figure 4C). |
