Abstract: To resolve the integer ambiguities of the GPS Ll and L2 carrier phases on the fly, two types of wide-lane phase combination are formed, resulting in 86.2 and 162.8 cm signal wavelengths, respectiuely. 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.P2.8 cm are achievable during low ionospheric activity.
