Further product information.

Spirent GNSS simulators recreate the RF signal environment based on test scenarios defining receiver position, environment, motion and other effects at a given time. Very challenging and realistic simulations are readily achieved, including low signal conditions, high dynamics, multipath modeling and interference enabling receiver performance to be tested in adversarial and error conditions.

Spirent GNSS is suited to a wide range of applications, from multiple test runs in a development environment to production and field-testing. The Spirent GNSS has been chosen by developers and manufacturers from a wide range of sectors including vehicle tracking and telematics, telecommunications, civil aviation, personal navigation and space since the Spirent simulators virtually eliminate the need to perform expensive field trials and provide an accurate, repeatable and controllable tool.

Key features:

Multiple Constellations Available
  • GPS, all legacy and modernized signals at all frequencies
