- Abstract
This paper is aimed at evaluating the performance of a Garmin GPSMAP 66sr multi-GNSS receiver via GNSS simulation. The study focuses on two important parameters in evaluating GNSS performance, namely performance under varying GNSS signal power levels and radio frequency interference (RFI). This study is conducted for the GPS L1 coarse acquisition (C/A) and Galileo E1 open service (OS) signals, for two conditions: 1) GPS only with six satellites (assuming an obstruction scenario with limited view of satellites); 2) GPS with six satellites and Galileo with six satellites. It is observed that at lower GNSS signal power levels and higher interference signal power levels, the higher number of GNSS signals observed for the GPS + Galileo mode allows it to have lower probable errors as compared to the GPS only mode. This highlights the advantage of multi- GNSS in degraded environments, such as dense urban and forest areas.
