| Abstract: | GPS ambiguity resolution is the process of resolving the unknown cycle ambiguities of double-difference (DD) carrier-phase
data as integers. It is the key to fast and high-precision relative GPS positioning. Critical in the application of ambiguity
resolution is its reliability. Unsuccessful ambiguity resolution, when passed unnoticed, will too often lead to unacceptable
errors in the positioning results. High success rates are required for ambiguity resolution to be reliable. In this contribution
we will introduce and evaluate such diagnostic measures. They complement existing methods of ambiguity resolution and allow
the user and/or analyst to infer their reliability. ? 1999 John Wiley & Sons, Inc. |
