A New Method of Ambiguity Resolution for Triple-Frequency GPS PPP
ITM Web of Conferences, 2016 At present, reliable ambiguity resolution in GPS precise point positioning (PPP) can be achieved through the traditional model called “EWL-WL-NL”. In this paper, we proposed a new model of ambiguity resolution,“WL-WL-WL”, where making use of linear ...
