Resource Portal for Resilient Positioning, Navigation and Timing

 

This page is designed to provide easy-access to resources and information for protecting and assuring position and time.

We have written some information ourselves, but much of the content is links to useful resources provided elsewhere.

This portal is intended as a resource to enable improved knowledge and understanding, in line with the Royal Institute of Navigation’s objectives. Please note that no liability can be accepted by the Royal Institute of Navigation for the use and interpretation of this data.

If you have comments or would like to add information or links to this page, please contact us via the form at the bottom of this page or e-mail us: RPNT@rin.org.uk
