Final Presentation NAVISP EL3-017 "UK Time Distribution" Date: 27/06/2025 – 10:30-12:00

The final presentation of the UK Time Distribution activity, developed by Chronos Technology Limited under ESA's NAVISP EL3-017 project, will summarize the outcomes of this initiative. UK Critical National Infrastructure (CNI) is at significant risk from the loss of access to GNSS for PNT. Low Frequency systems such as eLoran can provide a highly robust complement to GNSS. An eLoran transmitter can serve applications hundreds of miles away but the accuracy of the time transfer depends on the radio propagation (at ground level) between the transmitter and the receiver. At levels of precision required for many CNI applications the accuracy is significantly dependent upon the signal delay that the ground introduces, which varies according to several factors such as weather conditions. The UTD project addresses that knowledge gap, and the presentation will detail the measurement and results of the signal delay, providing a key step towards national exploitation of eLoran based precise timing transfer.

This activity was developed under NAVISP Element 3, which aims to support Member States objectives in the Positioning, Navigation and Timing/ domain. Please check the agenda and register for the event to learn more about this project.
