摘要: With the advent of modernized GPS, triple-frequency phase measurements (L1, L2, and L5) are available for civil use. The successful ambiguity resolution integer ambiguities will be key to centimeter-level positioning. In order achieve over long baselines, code (pseudorange) regularly incorporated with in observation model. However, multipath affects thus completely eliminating influence is an important issue. Therefore, present study proposes approach that uses only proposed has three steps focuses on resolving measurements. Simulation baseline data were processed by results show can successfully resolved satellite geometry factor phase-only performance. Real GPS from currently Block IIF satellites also demonstrate feasibility approach.
