A New Rapid Integer Ambiguity Resolution of GNSS Phase-Only Dynamic Differential Positioning
IEEE Geoscience and Remote Sensing Letters, 2021The methods using the linear combination or simultaneous equations of global navigation satellite system (GNSS) carrier phase and pseudorange as the observations have become the main technology applied in GNSS dynamic differential positioning. Though the

Aided integer ambiguity resolution algorithm
PLANS 2004. Position Location and Navigation Symposium (IEEE Cat. No.04CH37556), 2004The key issue in precise positioning using the GPS carrier phase is to solve for the integer ambiguities quickly and correctly. For some navigation applications, external sensors am available that provide auxiliary measurements. For example, in the control and guidance of land vehicles relative to a desired trajectory (e.g., lane-keeping on a highway ...

INS aided GPS integer ambiguity resolution
2011 IEEE International Conference on Control Applications (CCA), 2011Real-time high precision GPS positioning is based on carrier phase measurements, which requires fast and precise on-the-fly integer ambiguity resolution. In some navigation applications, external sensors are available that provide auxiliary measurements.

Applied Interval Based Integer Ambiguity Resolution
Navigation, 2009This paper provides improvements on the interval integer ambiguity resolution algorithm BOUNDS, which can give theoretical guarantees on finding the correct integers. The BOUNDS algorithm is validated by applying it to real GPS data and comparing it to the LAMBDA method.

Near-real-time GPS integer ambiguity resolution
IEEE Conference on Decision and Control and European Control Conference, 2011Real-time decimeter accuracy GPS positioning can be achieved using carrier phase measurements. This requires fast and reliable on-the-fly integer ambiguity resolution. However, in GPS challenged areas (e.g. Urban canyons, tunnels, thick canopy etc.) the GPS receiver may not be able to track a sufficient number of satellites to resolve the integer ...

Modified weighted integer least squares estimations for GNSS integer ambiguity resolution
Survey Review, 2013In this contribution, modified versions of Agrell, Eriksson, Vardy, Zeger (AEVZ) algorithms for integer ambiguity resolution of GNSS phase observations are presented. This modification removes many redundant mathematical operations of the AEVZ algorithm based on a recursive function.
