UKSAC25_0053 - PNT GNSS Receiver Jamming Testing

***** THIS IS AN AWARD NOTICE, NOT A CALL FOR COMPETITION ***** This procurement is being concluded following a mini competition under the Crown Commercial Services - RM6235 - Space Enabled and Geospatial Services Framework.

Multi-constellation receivers are often used to support resilience in the event of GPS signals becoming unreliable due to jamming, spoofing or degradation. These receivers use a range of Global Navigation Satellite Systems (GNSS) to provide PNT. In theory, these should provide seamless continuity of PNT data provision in the event of signals from the GPS constellation becoming unreliable, through using other GNSS constellations to provide PNT such as Galileo; however, there is currently a lack of understanding on how individual multi-constellation GNSS receivers respond to losing access to GPS signals.
