Abstract
Toyon Research Corporation proposes to develop and demonstrate a multipath mitigating antenna/receiver system for GPS geodetic applications. Our proposed system consists of a dual-channel antenna that provides spatial discrimination between the direct satellite signal and multipath signals, coupled with enhancements to the receiver architecture including multiple correlators to estimate multipath offset and pseudorange error filtering. We will evaluate and field-test these techniques in a software-defined GPS receiver testbed. The predicted net effect of the proposed antenna and receiver-based techniques is a reduction in the root-mean-square-error (RMSE) of the satellite pseudorange by a factor of eight (8).
