Research of Eliminating the Day-Boundary Discontinuities in GNSS Carrier Phase Time Transfer through Network Processing
TL;DR: The accuracy of time transfer has been significantly improved, and the frequency stability of UTC(NTSC)-UTC(PTB) can be up to 6.8 × 10−15 on average time of more than one day, which is suitable for continuous multi-GNSS time transfer, especially for long-term clock stability comparison.

Autonomous clock ensemble algorithm for GNSS applications
TL;DR: The US Naval Research Laboratory (NRL) developed clock ensembles for a number of vital GNSS projects and services throughout the US and international community Some efforts include algorithms for local realization of Coordinated Universal Time; participation in the upgrade of the Global Positioning System (GPS) system time; the initial implementation of a coherent geophysical reference time known as IGS Time (IGST); and development of various Department of Defense capabilities for the dissemination and transfer of precise time as mentioned in this paper.
