Integer ambiguity resolution in precise point positioning: method comparison [PDF]
Journal of Geodesy, 2010 Integer ambiguity resolution at a single receiver can be implemented by applying improved satellite products where the fractional-cycle biases (FCBs) have been separated from the integer ambiguities in a network solution. One method to achieve these products is to estimate the FCBs by averaging the fractional parts of the float ambiguity estimates, and

Real Time Attitude Independent GPS Integer Ambiguity Resolution [PDF]
The Journal of the Astronautical Sciences, 2004 In this paper, a new motion-based approach for Global Positioning System (GPS) integer ambiguity resolution is derived. The approach first represents the GPS sightline vectors in the body frame or the baseline vectors in the reference frame. The solution to this problem is always available as long as at least three non-coplanar baseline or sightline ...
