Spirent’s simulation systems have changed significantly from their technology beginnings, which can be traced back to World War II radars. The company and its technology have evolved to keep pace with today’s growing population of GNSS constellations and to meet the challenges that receiver manufacturers and users encounter in an ever-complex integrated GNSS environment.
In GPS World’s first-ever Simulator Buyers Guide, we feature simulator tools, devices, and software from eight prominent […]
It Doesn’t Have to Be ExpensiveGNSS signal simulators can be expensive and beyond the limited budgets of many researchers. In this month’s column, we look at one company’s approach to providing GNSS signal simulation at a low cost — one that virtually any researcher can afford.GNSS signal simulators can be expensive and beyond the limited budgets of many researchers.

CAST Navigation of Tewksbury, Massachusetts introduced its SGX GPS Satellite Simulator. With its compact size — 7 × […]
Testing GNSS Receivers with Record and Playback TechniquesIs there a way to perform repeatable tests on GNSS receivers using real signals? This month’s column looks at how to use an RF vector signal analyzer to digitize and record live signals, and then play them back to a GNSS receiver with an RF vector signal generator.
