Kinematic Positioning with GPS Carrier Phases by Two Types of Wide Laning

摘要

To resolve the integer ambiguities of the GPS L1 and L2 carrier phases on the fly, two types of wide-lane phase Combination are formed, resulting in 86.2 and 163.8 cm Signal wavelengths, respectively. Large lane spacings Facilitate the determination of a correct ambiguity vector By a least-squares trial-and-error approach, in which Double-difference phases between the satellite and the Receiver serve as a mathematical model. An algebraic Relationship of extra-wide-lane integer ambiguity to Wide-lane ambiguity is derived and used to advantage. Based on independently surveyed reference values of Short baseline vectors (<5.0 km), kinematic positioning Accuracies on the order of 0.4-2.8 cm are achievable During low ionospheric activity.
