Record and Playback for GNSS Testing

Record and playback (RP) systems are increasingly popular in the GNSS receiver testing and validation process. For this reason, it’s important to have a better understanding of the RP’s contribution to the tested receiver’s raw measurements. Through documented laboratory test results and real field-usage cases, this paper confirms that RP systems can replay previously recorded signals so that its impairments are undetectable or at least acceptable for most GNSS receivers/applications. As well, the RP significantly reduces the amount of time, and the number of resources, required when GNSS receivers have to be stressed in the presence of real-time, real-world signals. Read More
