SET-229 on “Cooperative Navigation in GNSS Degraded and Denied Environments” was formed to explore technologies that will enhance NATO military effectiveness, particularly in challenging indoor and urban environments, through the use of advanced, cooperative/collaborative navigation sensor technologies and integration techniques. In light of intentional (jamming and spoofing) and unintentional GNSS threats, the need for robust and accurate positioning, navigation and timing (PNT) systems in GNSS degraded or denied environments is critical to ensure mission effectiveness and minimize casualties and collateral effects. Unintentional GNSS threats (multipath, shading etc.) are present during operations in urban and indoor environments. There is also a growing need to maintain PNT capabilities in the Anti-Access/Area Denial (A2/AD) environment. In such environments, it may be difficult for NATO forces to gain access to the battlespace and conduct military operations.


The objective of this activity will be to hold an STO Symposium in Fall 2020 that presents the current state-of-the-art in cooperative/collaborative navigation sensor, integration & communication technologies. Expert researchers and engineers will provide presentations and papers describing the state-of-the-art in Cooperative/Collaborative Navigation technology, techniques, sensors, algorithms and integration used to provide PNT in GNSS Degraded/Denied environments. Through this RSY, the community will be updated on cooperative/collaborative navigation sensors, systems and operational integration techniques as practiced by leading experts in the field. In addition, there will be a session dedicated to sharing the results from the SET-229 Cooperative Demonstration. A full text version of the presentations and papers (Meeting Proceedings) will be prepared for distribution.
