MF/MC Receiver Performance Evaluation under Nominal Interference Conditions for Definition of Receiver Parameter Space

Abstract

Simulations with nominal continuous wave interference, broadband noise and pulsed interference were performed for evaluation of the receiver design space of a future multi-frequency multi-constellation GBAS ground receiver. Recorded data from hardware simulations with GPS L1/L5 and Galileo E1/E5a signals plus in-band and near-band nominal interference signals according to ICAO and EUROCAE standards were analyzed with a post-processing software receiver. In the software receiver different settings of the RF-bandwidth and early-minus-late correlator spacing were applied. In case of GPS L1 these settings represent the borders of the receiver parameter design space according to current standards.
