Performance Evaluation of GPS Single-Epoch On-the-Fly Ambiguity Resolution

摘要

GPS applications that require precise phase solutions in difficult environments, where loss of lock is likely, would benefit form instantaneous (single-epoch) phase integer ambiguity resolution. Among these applications are aircraft positioning and attitude determination during a photogrammetric flight, engineering surveying, and large-scale mapping. This paper reviews current GPS on-the-fly (OTF) Techniques; a single-epoch ambiguity resolution approach Is discussed in detail. Test results from 45 h of static Data and 105 min of kinematic data re presented.
