Abstract

The awareness of orientation of multipath is critical for site selection or for antenna accumulation, particularly in the applications like precise monitoring of earthquake movement and tsunami detection. This paper presents the analysis of the multipath error estimated on the L1 frequency (1575.42MHz) of all the GPS satellites that are visible from the Andhra University College of Engineering, Visakhapatnam. This analysis is useful in determining the location of the obstructions in the path between satellites and receiver. From this analysis the location of the satellite which is affected more by the multipath can also be determined. The analysis is done using the TEQC toolkit and the CF2SKY toolboxes [1, 2]. The analysis made in this paper is also useful in determining which location of the receiver antenna has more multipath and at which location it is less and thereby the antenna can be mounted at less multipath location.
