What is GNSS receiver testing?
Find out how GNSS receiver testing enables your customers to rely on the positioning and navigation of your products.
Building reliable products demands thorough testing and evaluation
With the increasing reliance on GNSS technology, it is important for designers, manufacturers and consumers of these products to understand what to expect from such systems. This includes formulating an understanding of the limitations and problems of technologies and how to test them.
No two GNSS receivers perform exactly the same, and there are no standardised measures to be provided in a specification. For this reason a series of fundamental tests must be carried out at every development stage.
Utilising GNSS simulation to evaluate a receiver
A GNSS simulator reproduces the environment of a receiver by modelling vehicle and satellite motion, signal characteristics, and other effects. Effective use of a simulator is the most valuable tool in GNSS receiver testing.
Six key receiver tests
Cold start time-to-first-fix
With no prior information
Hot start time-to-first-fix
With information already known
Lowest power to acquire lock
Lowest power to maintain lock
After signal has been lost
Static and dynamic

How to choose a GNSS receiver
Choosing the receiver for your GNSS-dependent device is a key step in product development. However, with so many products on the market, how do you decide which one is best suited to your needs? And how do you find out how it will perform post-integration?
Automotive Positioning – GNSS Receiver Selection Challenges
The rise of automation in automotive is changing the role of positioning technology. GNSS has moved from being a convenience feature to acritical component with implications on functional safety.
