Abstract:	New Global Navigation Satellite System (GNSS) satellites will bring common, interoperable GNSS signals on L1. These new signals, L1C Global Positioning System (GPS)/Quasi-Zenith Satellite System (QZSS) L1C and Galileo E1 Open Service (OS), promise performance improvements in many areas. One key area is that these signals, which use binary offset carrier (BOC) and multiplexed BOC (MBOC), will provide better multipath performance over the binary phase shift keyed (BPSK) GPS L1 C/A. This paper evaluates the benefit of difference using on-air measurements of these signals. The evaluation will utilize signals from to-be operational Galileo and QZSS satellites. The assessment conducts BPSK and BOC processing using signals from the same satellite to eliminate the effects of geometry.
