Ambiguity Resolution on the Fly (AROF); Results, Facts, Limitations

Erwin Frei, Joan Yau, and Daniel Sauer

Abstract:	In order to investigate the potential and the accuracies to be achieved with Leica’s new Ambiguity Resolution Qn the Ely (AROF) technique, various tests were conducted in Spring 1993 with the Wild GPS System 200. The measurements were evaluated with the new “AROF” - option of the SKI post-processing software. This paper presents the performance and accuracies obtained in these tests utilizing the new “AROF” capability. It also discusses possible limitations and problems to be obeyed when taking observations as well as analyzing the measurements. In addition, the influence and behavior of systematic error sources, e.g. ionosphere, is studied as well as possible methods to detect such distortions. Finally, this paper presents a conclusion concerning the impact of “AROF” - techniques on the way surveying with GPS is handled in the future.
