Abstract:	We propose a method based on Array Antenna and GNSS Array Receiver on board of a LEO space platform (16U CubeSat), that performs real-time Jamming and Spoofing detection and monitoring, enables DoA of navigation satellites and potentially geolocalization of RFI sources (earth or on space). At the same time the, proposed system solution protects the asset in space from such threats, still providing PVT.
