Abstract:	Abstract—This study describes the improved ambiguity resolution of real-time kinematic positioning global navigation satellite system (GNSS) in a complex environment. We focus on the algorithm to resolve the initial ambiguity resolution where the GNSS antenna is mounted on a wall and the opposite side is surrounded by walls. To resolve integer ambiguities under the multipath-contaminated considerably masked condition, a unique approach is used to determine correct fixed positions. Several test results are considered to evaluate the proposed algorithm. These results demonstrated that the new method provides quick reliable ambiguity resolution. Keywords—RTK-GNSS, integer ambiguity resolution, multipath
