GMV NSL's unprecedented understanding of the threats and vulnerabilities to GNSS and the RF environment, allows us to test GNSS-based units in terms of their security, functional and operational performance.


GMV NSL provides services to test commercial devices that have been submitted for type approval against detailed functional and non-functional requirements. This includes, for example:

  • Testing the performance of single-constellation, multi-constellation and augmented GNSS
  • Performance testing under nominal, degraded and denied scenarios
  • Testing the Time-To-First-Fix and other performance metrics in the presence of obstructions
  • Testing the communications system performance and power management capabilities
  • Testing the resilience against signal interference, spoofing and jamming
  • Testing the vulnerability to tampering and unauthorised external inputs
  • Analysis of the reporting history to identify event characteristics and derive common indicators for incidents, attacks and aberrations
  • For further information on these services, please either email or telephone GMV NSL.
