This REISSUED EXPRO+ procurement is part of the NAVISP Programme, under Elelment 1, Work Plan 2018.An accurate, secure and reliable time transfer is a key enabler for emerging fixed and mobile services worldwide. A number of different applications like autonomous vehicles, terrestrial positioning, 5G mobile broadband, mobile multimedia broadcast, power grids, terrestrial positioning services, financial operations, IoT, big data and cloud processing will require secure and reliable time information to be able to work correctly and efficiently. The time information will not only need to be transferred securely, but also accurately and in a seamless and ubiquitous manner, which is quite challenging for solutions based on GNSS only.Based on the above it seems necessary to put forward innovative and complementary methods of time transfer, focusing on the use of non-GNSS technologies. In order to enable an overall seamless provision of secure, ubiquitous and reliable time information, alternative solutions will be conceived to complement thecurrent GNSS time transfer techniques with the emerging fixed and mobile servicesThe main objective is to demonstrate feasibilityof time transfer using GNSS complementary technologies (e.g. signals of opportunity from LEO constellations or terrestrial infrastructure) that would provide secure, ubiquitous, and reliable time information.The activity shall focus on efficient and affordable implementations of time transfer techniques leveraging existing and emerging space-based and terrestrial technologies.
