Tutorial: GPS Receiver Testing

As GPS technology becomes more commonplace on the commercial market, many designers are working to improve characteristics such as lower power consumption, the tracking of weak satellites, faster acquisition times, and more accurate position fixes. In this article, learn how to make a variety of GPS receiver measurements including sensitivity, noise figure, position accuracy, time to first fix (TTFF), and position deviation. The goal of this document is to provide engineers with a thorough understanding of GPS measurement techniques.
