A Special Method of Managing Multipath Effects

D. Becker, K. H. Thiel, and Ph. Hartl

Abstract:	The influence of multipath signals on GPS carrier phase and code phase measurements, reflects a severe problem in all high-precision applications, even in differential mode. In the case of attitude determination, it is one of the most significant error sources that causes extreme results especially when using short baselines. On the other hand, a platform arrangement of three or more antennas provides a good opportunity for deriving methods for the detection and modelling of the multipath effects. This will be done especially to examine the quality of the site of a reference ground receiver. The advantage of such a system is the well-defined geometry of the installed antennas in addition to the high redundant range measurements. Based on an amount of significant data sets gathered in real environments, a special method has been developed to detect and even to describe the multipath influence. This paper presents the evaluated algorithms and the results of various measurements.
