A Study of Evaluation Method for GPS-L5 Signal Environment during Flight Experiments

摘要

The operational performance of radio navigation systems in ARNS (Aeronautical Radio Navigation Service: 960 - 1215MHz) band are required to be estimated whether or not they will interfere harmfully with each other by shareing the frequency band. The performance of these systems will be estimated with some interference measures such as the received pulse power distribution. For example, the wide band signal of GPS-L5 will be interfered with by channels of DME (Distance Measurement Equipment) signals. This paper reports the on-board measurements using the wideband and longtime waveform recorder for the signal environment in ARNS band.
