摘要：Precision, Navigation, and Timing (PNT) system based on Global Navigation Satellite System
(GNSS) becomes significant in the air, land, and sea traffic management. Integrity of GNSS is significant to
provide a reliable real time PNT system such as CORS (Continuously Operating Reference Stations).
GNSS Interference due to intentional or unintentional surrounding signal source may decrease the integrity
of GNSS signal. Monitoring and identification of potential GNSS interference sources in the surrounding
environment of CORS is significant. This paper proposed a methodology to reduce potential GNSS
interference in a planned CORS site by first simulating the radiation pattern of potential source of
interference to GNSS signal in the planned CORS sites. Thereafter ambient noise levels in the location of
CORS may be measured to provide a reference point for analyzing the other potential sources of
interferences. Based on these results, optimal location of CORS is chosen with the lowest possible
unintentional interference signal from their surrounding. Measurement has been conducted in the location
of CORS owned by BIG (Indonesian Agency for Geospatial Information), which is located in the rooftop of
a building neara telecommunication tower.This method is necessary for CORS site planning to reduce
potential GNSS interference sources in the environment of alternative sites.
