Abstract

A global navigation satellite system receiver with filter bypass mode for improved sensitivity is disclosed. In an aspect, an apparatus is provided that includes a non-bypass signal path coupled to a receiver, the non-bypass signal path comprising a filter. The apparatus also includes a bypass signal path coupled to the receiver, the bypass signal path configure to bypass the filter, and a switch to couple an antenna to the non-bypass signal path during time intervals when signals transmitted by an unrelated local transmitter are transmitted with a signal power that exceeds a selected threshold, and to couple the antenna to the bypass signal path during other time intervals.
