A canonical theory for short GPS baselines. Part III: the geometry of the ambiguity search space
Abstract. This contribution is the third of four parts. Based on the gain-number concept, canonical forms will be presented of the ambiguity search spaces of the geometry-based model, the time-averaged model, and the geometry-free model. These forms reveal the intrinsic geometry of the search spaces and allow one to study their size, shape, and orientation as function of data precision, sampling rate, satellite redundancy, and change in receiver-satellite geometry. The canonical forms are also used to address the problem of search halting. The phenomenon of search halting is explained and it is shown how decorrelating ambiguity transformations can largely eliminate this computational burden.
