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. This method is optimal in the sense that it achieves the highest success rate of all … Nettet1. jun. 2009 · When it comes to ambiguity resolution-enabled PPP, three main models exist and have been used: the Fractional Cycle Bias (FCB) model (Ge et al., 2008), the … blitz acrylic spray sealant
