Investigation of Galileo E1 OS/SoL Acquisition, Tracking and Data Demodulation Thresholds for Civil Aviation

Olivier Julien, Jean-Luc Issler, Lionel Ries

Abstract:	The present article intends to propose acquisition, tracking and data demodulation thresholds for Galileo E1 OS civil aviation receivers. These thresholds are a mean to ensure that the performance of a simple Galileo E1 receiver is compatible with the civil aviation requirements related to the acquisition, tracking and data demodulation functions. The methodology to do so is taken from similar work realized by the Radio Technical Commission for Aeronautics (RTCA) for GPS, and adapted to the Galileo case. The proposed threshold values are a post-correlation C/N0 threshold of 32 to 34 dB-Hz for acquisition and 29.5 dB-Hz for tracking and data demodulation.
