How to Meet the Demanding Challenges Involved in Testing GNSS Receivers?

Modernization of GNSS systems have demanded the validation of receiver performance for all new upcoming signals. The traditional live antenna analysis can no longer be used to validate all kinds of signal/ environment / user scenarios which has lead to the introduction of GNSS simulators. With the help of GNSS simulators, users are now able to test the receivers in lab for all kind of critical signal conditions including vehicle modelling and satellite motion, GNSS signal structure & atmospheric and other environmental effects that can affect receiver performance. us, simulations can provide a controlled, reliable and repeatable way to test and adequately identify any receiver design limitations. In this article, the various challenges involved in testing GNSS receivers are highlighted. Methodologies to effectively validate the receivers using simulators are provided along with Accord GNSS Simulator products.
