Record and Playback for GNSS Testing: High Performance for Real Applications

Record and playback (RP) systems are increasingly popular in GNSS receiver testing and validation. For this reason, it's important to have a better understanding of the RP's contribution to the tested receiver's raw measurements, such as when the RP is placed between the signal source (e.g., GNSS satellites and an interference source) and the unit under test (UUT). Read this white paper to learn how Averna's RP can replay signals so that its impairments are undetectable or irrelevant for most GNSS receivers/applications, while reducing the time and resources required for real-time, real-world GNSS signal testing.
