Studying the Effects of Interference on GNSS Signals

Assessing the impact of interference on live GNSS signals is a slow and challenging process, with many uncontrollable environmental factors.

In this paper, Spirent’s test engineers describe how to conduct such tests in repeatable laboratory conditions, and reveal the effects of five different interference sources on the tracking capability and navigation performance of a commercially available GPS receiver.
