Efficiency 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...
متن کاملLeast Squares Techniques for GPS Receivers Positioning Filter using Pseudo-range and Carrier Phase Measurements
In present study, using Least Squares (LS) method, we determine the position smoothing in GPS single-frequency receiver by means of pseudo-range and carrier phase measurements. The application of pseudo-range or carrier phase measurements in GPS receiver positioning separately can lead to defects. By means of pseudo-range data, we have position with less precision and more distortion. By use of...
متن کاملRank-defect integer estimation and phase-only modernized GPS ambiguity resolution
Carrier-phase ambiguity resolution is usually based on the assumption that the underlying model of observation equations is of full rank. In this contribution the model of observation equations is assumed to be of less than full rank. The well-known three-step procedure of integer least squares is generalized and it is shown how the solution can be affected by the rank deficiency. Although the ...
متن کاملThe accurate optimal-success/error-rate calculations applied to the realizations of the reliable and short-period integer ambiguity resolution in carrier-phase GPS/GNSS positioning
The maximum-marginal-a-posteriori success rate of statistical decision under multivariate Gaussian error distribution on an integer lattice is almost rigorously calculated by using union-bound approximation and Monte Carlo integration. These calculations are applied to the revelation of the various possible realizations of the reliable and short-period integer ambiguity resolution in precise ca...
متن کاملAn IMU-Aided Carrier-Phase Differential GPS Positioning System
We consider the problem of carrier-phase differential GPS positioning for an land vehicle navigation system (LVNS), tightly coupled with an inertial measurement unit (IMU) and a speedometer. The primary focus is to apply Bayesian network to an IMU-aided GPS positioning system based on carrierphase differential GPS. We describe the implementation details of the positioning system that integrates...
