A previous RTG (SET-167/RTG-094) on “Navigation Sensors and Systems in Global Navigation Satellite System (GNSS) Denied Environments” conducted a program of work from 2010 to 2014 in which NATO experts from government, academia, industry, and the military assessed and forecasted advances in the field of navigation sensors applied to operations in challenging environments where GNSS are degraded or denied. The group also held a symposium (SET-168) and a lecture series (SET-197) on these topics.
Almost all of the networked, collaborative systems being developed or envisioned today require an exact knowledge of position, orientation and time data to be able to fulfil their objectives. Generally this navigation requirement is pivotal to the success of the system, yet is often overlooked in favour of other technological challenges. This topic is essential in the success of NATO LTCR 1, 2, 8, and 9 while affecting almost all.
The group will execute a four year effort to explore multiple solutions for an interoperating team to maintain accurate and reliable navigation (i.e. position, velocity, and orientation) in a GNSS degraded/denied environment. Each participating nation will develop its own sensor suite and navigation algorithm for a platform, and each nation’s platform will communicate with platforms developed by other nations. The group also will explore the development of a set of standards for communication to enable cooperative navigation.
A technical report will be produced that describes the standards for cooperative navigation and general results from interoperational tests. The group will also hold a symposium on these topics and possibly conduct a lecture series as well.
Inertial sensors; sensors for measuring relative range and/or bearing to other platforms; multiple GNSS constellations; communication hardware for sharing navigation information
