GPS/GNSS Testing for Space-Based Applications

High Performance Simulation Solutions for Space-Based GPS/GNSS

Many spacecraft rely on GNSS as a key element of positioning and attitude determination. In a space environment, trial and error testing is not an option. Simulation and test of spacecraft GNSS components (typically GPS, Galileo and SBAS receivers) is a key element of design and qualification for all space projects.

Spirent Solves Critical Test Needs for Space Applications.

Spirent offers comprehensive test capabilities for space-based GNSS applications. Many of the world's leading Space Agencies and space-related companies use Spirent's GPS and GLONASS simulation systems today. Applications range from simple single frequency testing through multi-output, multi-frequency configurations. Spirent's Galileo simulators are being widely adopted as a test standard for demanding projects related to the implementation of the Galileo system.
