Using phase ambiguity resolution for millimeter-level rail positioning
IEEE 2000. Position Location and Navigation Symposium (Cat. No.00CH37062), 2002The Applied Research Laboratories, The University of Texas at Austin (ARL:UT), has developed a prototype rail surveying system that utilizes a self-propelled railcart, along with a network of reference sites, and phase ambiguity resolution software to provide millimeter-level survey capability.

The Effects of GPS Carrier Phase Ambiguity Resolution on Jason-1
Marine Geodesy, 2004We have used GPS carrier phase integer ambiguity resolution to investigate improvements in the orbit determination for the Jason-1 satellite altimeter mission. The technique has been implemented in the GIPSY orbit determination software developed by JPL.

Phase coding for the resolution of range ambiguities in Doppler weather radar
Conference Record of the Thirty-First Asilomar Conference on Signals, Systems and Computers (Cat. No.97CB36136), 2002This paper deals with the recovery of Doppler velocities in the presence of overlaid echoes in range. Transmitted pulses are phase shifted to tag the echoes from scatterers separated by the unambiguous range. A new systematic phase code and an algorithm for estimating the mean velocities of 1st and 2nd trip signals when they are overlaid are presented.

On‐the‐fly carrier phase ambiguity resolution for precise aircraft landing
International Journal of Satellite Communications, 1994AbstractSuccessful GPS on‐the‐fly (OTF) carrier phase ambiguity resolution for precise positioning at the centimetre level has already been demonstrated. This has usually been in good observation conditions, e.g. over short distances, lots of satellites, P‐code pseudoranges available, and small unmodelled errors. In order for GPS to fulfil the rigorous

Integer phase ambiguity resolution method for absolute GLONASS observations
Modern astronomy: from the Early Universe to exoplanets and black holesWith the help of modern navigation satellite systems it is possible to determine the coordinates of points with millimeter accuracy due to the precision measurement of the carrier phase of the navigation radio signal. However, in the course of achieving this accuracy, a nontrivial problem of resolving the integer phase ambiguity arises.

GPS Phases: Single Epoch Ambiguity and Slip Resolution
1996An observational equation of the GPS carrier phase contains the pair station — satellite specific and epoch independent bias γ r s = ψ s (t 0)−ψ r (t 0) +N r s , in which N r s is an integer ambiguity and ψ (t 0), ψr(t 0) are transmitter and receiver initial phases.
