Integer ambiguity resolution

Nettet29. nov. 2013 · Integer carrier phase ambiguity resolution is the key to fast and high-precision global navigation satellite system (GNSS) positioning and application. Apart from integer estimation, also acceptance tests are part of the ambiguity resolution process. A popular acceptance test is the so-called ratio-test. Nettet1. jan. 2012 · The satellite-based positioning system can provide centimeter-level positioning accuracy by processing carrier phase measurements in differential mode, however it is a challenge to fix the...

Nettet23. mar. 2012 · Integer ambiguity resolution in Precise Point Positioning (PPP) can shorten convergence time and improve accuracy significantly. Uncalibrated Fractional Offsets (UFOs) originating in the satellites destroy the integer nature of carrier phase ambiguities observed at a single station. NettetThe method of integer least-squares ( ILS s) ambiguity resolution is described in Sect. 23.4.

NettetThe decision whether or not to use the integer ambiguity solution is then based on the thus computed value of the failure rate. This approach is termed model-driven, since … NettetTo improve accuracy and reduce position convergence times, CSRS-PPP version 3 implements ambiguity resolution. This process can be divided into two concepts: 1. the estimation of carrier-phase ambiguities having integer properties, and 2. the validation of integer ambiguities.
