Final Presentation of NAVISP Project EL2-062 now available:

On Thursday, March 03, 2022, GMV (Portugal) presented the results of the NAVISP project “GNSS Signal Quality Monitoring for New Integrity Applications (MONINT).” About 50 people from industry and research followed the interesting presentation and the subsequent interactive Q&A session.
The project's main objective was to develop a platform that supports the definition, study, and performance assessment of Signal Quality Monitors (SQM) to detect Evil Waveforms. Evil Waveform is a rare deformation of the broadcast satellite navigation signal that, if not detected, would lead to positioning errors in user receivers. More specifically, the project aimed at exploring innovative solutions for a cost-efficient and flexible SQM solution for different markets, as well as developing a SQM prototype that is supported by the dedicated test platform with radio frequency (RF) signal generation capability and receivers in the loop.
The SQM was analysed at both correction service and user processing levels in order to mitigate signal deformation threats on both sides. The resulting solution is expected to be cost-effective and thus promising for the massive deployment in user terminals, for example, in autonomous vehicles. 
Thanks to the support of NAVISP, GMV, together with its consortium partner Instituto de Telecomunicações, has succeeded in developing a promising platform that can be integrated in the near future in user terminals to increase the robustness and accuracy of PNT data and services.  
The project was part of NAVISP Element 2, which aims to maintain and improve the capabilities and competitiveness of the participating States' industry in the global market for satellite navigation and, more broadly, PNT technologies and services.
