Theory of Carrier Phase Ambiguity Resolution
Carrier phase ambiguity resolution is the key to high precision Global Navigation Satellite System (GNSS) positioning and navigation. It applies to a great variety of current and future models of GPS, modernized GPS and Galileo. A proper handling of carrier phase ambiguity resolution requires a proper understanding of the underlying theory of integer inference. In this contribution a brief revi...
متن کاملStatistical Gnss Carrier Phase Ambiguity Resolution: a Review
Abstract Global Navigation Satellite System carrier phase ambiguity resolution is the key to high precision positioning and navigation. In this contribution a brief review is given of the probabilistic theory of integer carrier phase ambiguity estimation. Various ambiguity estimators are discussed. Among them are the estimators of integer rounding, integer bootstrapping, integer least-squares a...
متن کاملGNSS Carrier Phase Ambiguity Resolution: Challenges and Open Problems
Integer carrier phase ambiguity resolution is the key to fast and high-precision global navigation satellite system (GNSS) positioning and application. Although considerable progress has been made over the years in developing a proper theory for ambiguity resolution, the necessary theory is far from complete. In this contribution we address three topics for which further developments are needed...
متن کاملWide-Area, Carrier-Phase Ambiguity Resolution Using a Tomographic Model of the Ionosphere
A method for resolving GPS carrier-phase ambiguities exactly at hundreds of kilometers from the nearest reference site has been tested under a variety of operating conditions, with help from a computed tomography model of the ionosphere. The objective is decimeter-level (root mean square) wide area kinematic positioning in real time using broadcast orbits, and subdecimeter-level positioning usi...
متن کاملEfficiency of carrier-phase integer ambiguity resolution for precise GPS positioning in noisy environments
Precise GPS positioning relies on tracking the carrier-phase. The fractional part of carrier-phase can be measured directly using a standard phase-locked loop, but the integer part is ambiguous and theambiguity must be resolved based on sequential carrier-phasemeasurements to ensure the required positioning precision. In the presence of large phase-measurement noise, as can be expected in a jam...
