Interference immunity for navigation services

The use of Global Navigation Satellite System (GNSS) satellite based navigation is ubiquitous where signals are used for both precision position and timing information. All systems, be they established or emerging, exploit predominantly low power, spread spectrum signals (typically -130dBm at the Earth’s surface) which are susceptible to both interference (intentional or otherwise) as well as “spoofing” (the deliberate misinforming of the system). This proposal covers part of the roadmap to develop our interference protection technology into a modular, adaptable product family that provides interference immunity.
