Advanced Interference Monitoring
Sensors

QASCOM develops QB100, a solution for the detection, characterization and localization of interferences. QB100 is a radio device that monitors the spectrum and detects jamming and spoofing in the GNSS band.

Once an event is detected QB100 reports the interference to control servers that can generate alerts and notify the user. When a total of at least four sensors are used, the technology can localize the source of the interference on a map.

QB100: Advanced Interference Monitoring Sensor
The New Frontier of GNSS Signal Intelligence

QB100 is an advanced interference monitoring sensor. It can be deployed in standalone or cluster mode (allowing interference localization features).

QB100 is intended to be integrated in complex middle-wares and business intelligence applications, offering leading edge interference monitoring features to Value Added Resellers.
