Block-box is an external RF2RF device targeting the enhancement of any COTS GNSS receiver. It can be tuned to a variety of applications at user, downstream services or system level supporting monitoring functions and real-time signal cleaning. It is based on AI helping to detect and categorise signal system anomalies a well as Radio Frequency Interference/Spoofing detection, classification and mitigation. These detection capabilities will aim to be remotely upgrade able with newly trained models in order to, for example, keep up with constantly expanding and increasingly sophisticated RFI/jammer new technologies. Observations are based on measurements directly computed in the block-box from its GNSS spectrum (IF) samples and on measurements coming from the associated COTS GNSS receiver and enhanced by the Block-box. Block-box will also operate real-time rejection of interfering signals to produce a baseband/IF sample stream which is then upconverted to RF and injected in the coupled COTS GNSS receiver. In order to support monitoring functions, block-box will buffer recent IF samples to capture the period around an event detection. These samples can be stored and used later, for example, to test and tune new receiver algorithms. Extra parameters for integrity are also targeted in the block-box by enhancing the raw measurements of the GNSS receiver and the detection of satellite signal anomalies, e.g evil waveforms, exploiting the capability to connect multiple devices together via cloud architecture.
