GPS signals are extremely low power by the time they reach the Earth’s surface or typical flight levels above the Earth. This makes the signals vulnerable to interference, both intentional and unintentional.

Spirent has a comprehensive range of systems to enable controlled, repeatable testing with GPS signals in the presence of intentional or unintentional interference.

TECHNOLOGY

Over the years a number of schemes have been developed to mitigate the effects of jamming and unintentional interference on GPS signals. These include coupling GPS with Inertial sensors and adaptive antenna technology.

Testing such schemes requires specialized systems which stimulate the unit under test with GPS, simulated jamming/interference signals and inertial sensor simulation, as appropriate for the test situation.

Please contact your Spirent sales representative to discuss your requirement and our solutions in this area in more detail.
