Generating Distorted GNSS Signals Using a Signal Simulator
In this month’s column, our authors discuss a set of GPS and Galileo evil-waveform experiments they have carried out with an advanced GNSS RF signal simulator. Their results will help to benchmark the effects of distorted signals and perhaps lead to improvements in GNSS signal integrity. read more

GNSS Test Standards for Cellular Location

May 1, 2013By
Downtown Seattle, a typical test-case environment.

GNSS receivers in cell phones will soon support four or more satellite constellations and derive additional location measurements from other sources: cellular location, MEMS sensors, Wi-Fi, and others. The authors propose test standards covering these sources, meeting industry requirements for repeatable testing while considering the user experience. read more

Expert Advice: The Challenge of BeiDou

May 1, 2013By

By Mark Sampson, Racelogic GNSS is changing. The days of only American GPS satellites providing signals to the civilian population are gone as new constellations are launched. GLONASS was a slow starter, but is now well established, and its signal architecture is now commonly implemented in manufacturers’ chipsets. Galileo is still very much in test phase with global coverage planned... read more

Out in Front: The System, Simulated

May 1, 2013By

Wealth, breadth, and depth. That’s what this issue brings you, in signal simulation- and testing-related content. Unfortunately, the wealth on offer has to large extent elbowed out our two news sections, The Business and The System. The former is given short shrift in this issue and the latter even shorter herewith, in pithy precis with website shortcuts. And our apologies.... read more
