Strategies for testing and certification

Every product and system that uses a Global Navigation Satellite System (GNSS) requires rigorous testing to confirm its accuracy, performance and characteristics.

Working with Spirent Communications, CBIL can provide you with our ‘Sky in a Box’ – a simulator that provides RF signals to a GNSS receiver as if it were looking at actual, live satellites. It works with all constellations including GPS, GLONASS, Galileo, QZSS, MSAS, EGNOS, WAAS and Compass.

Using a carefully considered simulation strategy, you can reproduce the effects of the real world as a whole, or break them down into the individual elements and combine as required. The simulator can recreate positions anywhere in the world, at any time (past, present or future). You can also overlay any three-dimensional motion that you wish to test, including high velocity, rapid acceleration and extreme levels of jerk. These variable parameters mean that you can run an infinite number of ‘What If?’ scenarios.

These activities demand levels of accuracy, repeatability and traceability that can only be offered by a test methodology based on precision test equipment in a well-controlled environment. A detailed strategy will maximise test effectiveness and efficiency, ensuring your product is fit for purpose whilst minimising your development cycles.

CBIL will work with you to help write your test strategies and develop sophisticated satellite radio frequency and inertial simulations that can readily be used to provide comprehensive test coverage for your product.

CBIL can help you by:

  • Advising on the design of test strategies for GNSS and inertial based systems
  • Assist with the selection of simulation systems
  • Advise on correct deployment of simulators for “hardware-in-the-loop” testing etc
  • We can also devise GNSS RF simulator-based test scenarios
