Quick Solution of GPS Ambiguity Using LAMBDA

GPS precise and accurate positioning for navigation, mapping and geodesy requires a dual-integral carrier phase solution. The solution to this problem is the LAMBDA method of modulating separation of least squares’ correlation, so that LAMBDA is considered to quickly solve GPS ambiguities. In this paper, practical results are presented of positioning and resolution of ambiguity for several times. In 1993, Peter Tenissen, Professor of Mathematical Sciences at Delft, introduced LAMBDA as a dual-differential solution. LAMBDA method was implemented and its description and code is accessible at the following URL: Internet - site of MGP: http: // www.geo.tudelft.nl/mgp/ The LAMBDA method was used in 60 universities, institutes and companies.
