Integer Ambiguity Estimation for Satellite Navigation

IEEE Transactions on Signal Processing, 2012
Carrier phase measurements of pseudoranges often allow for millimeter precision. The periodic nature of the carrier phase, however, leads to integer ambiguities. These ambiguities need to be resolved for accurate positioning. Blewitt and Teunissen provide two methods for the associated estimation process.

Some remarks on GNSS integer ambiguity validation methods

Survey Review, 2012
AbstractAmbiguity resolution is an indispensable step in fast and high precision Global Navigation Satellite System (GNSS) based positioning. In general, ambiguity resolution consists of three steps. The first step is to estimate the ambiguities using a least-squares estimation process, from which the so called ‘float solution’ or real valued solution ...
