Real-World Tests for GNSS Receivers
Cities represent particularly diffi cult conditions for satellite-based navigation systems as a result of obscuration and multipath propagation. So how does one ensure that a receiver is up to the challenge? This white paper discusses the challenges of GNSS design for real-world conditions and the functionality to look for when selecting GNSS test simulators.

Spectracom – What is a GPS Simulator?
As GPS receivers are built into more mission-critical devices for difficult application environments, and designed with the emerging capabilities of a multitude of GNSS constellations and augmentation systems, developers and manufacturers need better ways to guarantee performance. That’s where a GPS simulator comes in.

Spirent: Testing Multipath Performance in GNSS Receivers
Reflected signals — for most GNSS applications, a troublesome and undesirable phenomenon. But exactly how does multipath affect GNSS receivers, what are the different types of multipath, and how do GNSS receiver designers mitigate its effects? This overview of nine different types of multipath describes how a GNSS simulator offers a practical capability to test multipath that is both accurate and repeatable in the controlled environment of the test laboratory.
Spirent: Testing GNSS Receiver Design – Simulators Versus the Real World
The real world can be a beautiful and exciting place — but it’s not always the best environment for testing GNSS receiver designs. This eBook examines nine key tests that together measure the performance of any GNSS receiver and how simulators are an essential tool in evaluating this performance.
Spirent – A Guide to GNSS Production Testing
Testing GNSS equipment designs and performance doesn’t end in the laboratory — or, at least, it shouldn’t end there. When the product moves into production, the objective becomes how to ensure that every single unit leaving the factory will perform exactly as it should. In the GNSS signal-challenged environment of a production facility, this is a job that simulators can handle.
Spirent – The Role of Simulation in the Integration of GNSS Receivers
Many GNSS receivers are stand-alone devices. Increasingly, however, receivers are being integrated with other sensors and electronic equipment into completely new systems. A ready-made receiver sub-assembly may be slotted into the integrated system or a lower cost chipset may be used together with peripheral components, which will require considerably more engineering effort. Selecting the correct receiver for the job is only half the story. Integrating the receiver circuits with the other circuitry of the equipment is a whole other task, which the right simulator can help accomplish.
Spirent: Test Solutions for Multi-GNSS Navigation and Positioning
Navigation and positioning technology is no longer just about GPS L1 C/A code. GPS is being modernized, the GLONASS constellation is nearly complete, new systems including QZSS, Galileo and Compass are on the way. Multi-GNSS offers significant opportunities and challenges to GNSS technology, system and application developers.

National Instruments: The Case for GPS Simulation
For each of the many steps that a GPS receiver must go through in order to accurately provide position and timing information, errors are introduced. By testing each step in an isolated fashion and with controlled introductions of signal impairments, receiver designers can target their troubleshooting and invest in areas of the design that will offer the greatest returns.
