GPS Receiver Verification Tests Using a GPS Signal Simulator

Show Description

Introduction

This paper describes a set of typical GPS receiver verification tests using a GPS signal simulator. These tests are used to verify the functionality of embedded GPS receivers in mobile consumer products such as cellular phones and other handheld receivers. Using a metric grade GPS signal simulator in a GPS receiver test environment provides regulated control, easy repeatability, and maximum flexibility. In this environment, the tests listed in this paper create a standard validation procedure for the testing and verification of most GPS receivers. The flexibility of the signal source allows for testing of not only GPS receivers but other wireless formats and standards as well.

 

Global Positioning System (GPS) receiver technology is now commonplace in our daily lives, having penetrated our electronicworld from cell phones, to personal navigation devices (PND), to cameras, to assimilation with RFID tags. The technology is rapidly expanding its reach into new areas, enlarging the ever-expanding role that GPS technology will play in our lives.
