Realtime GNSS Signal Denial
GNSS is becoming increasingly popular for applications regarded as non-critical, such as in-car SatNav, as well as for those that concern safety and financial transactions.
The performance of GNSS-based systems deteriorates when the direct signals from the satellites are blocked and when they are subjected to interference. As a result, the ability to simulate signal blockage via urban canyons and tunnels, and signal interference via jamming and spoofing has grown fundamental in testing applications.

Based on NSL's GNSS RF front end and SDR capabilities, SkyClone delivers a solution for the testing of GNSS based devices and services within a virtual city. 
SkyClone Conceptual Diagram Users design their virtual city by placing buildings, jammers and tunnels within an actual vehicle testing site within the SkyClone Office software. The design is then transfered to the in-vehicle SkyClone equipment and the test vehicle drives around the circuit. SkyClone digitises the incoming GNSS signal and, according to the virtual city, removes blocked satellites, attenuates multipathed signals and adds interference patterns. The revised signals are then turned back into analogue and either transmitted through air or injected directly into the vehicle's satellite navigation antenna feed. By completing this process in under 3 milliseconds, SkyClone delivers realtime controllable and repeatable GNSS-denial for the testing of GNSS based devices and services. SkyClone Datasheet |
