Abstract

In this contribution an overview is given of the capabilities of methods for ambiguity resolution in use nowadays. This is done in the context of SSG 1.157, “Ambiguity Resolution and Validation”, although the overview is not restricted to the algorithms used within this group.

Methods from the fields of navigation, rapid static surveying, and regional networks are compared, and similarities and differences are indicated. It is shown that the subdivision of the algorithms by their applications is a rather arbitrary one, and that some of the ambiguity resolution algorithms can be applied in all three fields.

The capabilities of state of the art algorithms for ambiguity resolution are indicated in terms of maximum distances over which the ambiguities can be resolved and validated. In particular the role of the observational time span and the set of observables used in the estimation (single versus dual frequency, phase-only versus phase and pseudo range) is addressed. As the ionospheric delay is an important reason for being unable to resolve the ambiguities, the consequences of the next solar activity maximum at the end of the century are briefly discussed.
