Current GPS/GLONASS Time References and UTC

Abstract

The world's two global satellite navigation systems, GPS and GLONASS, will both become operational during the early 1900's. Each will offer, independently of the other, precise location and time transfer continuously anywhere in the world and indeed in space itself. Many potential users, in particular the civil aviation community, are keenly interested in a joint GPS/GLONASS operation since it would offer substantial advantages in defining and maintaining the integrity of the navigation aid. The question arises of compatibility of GPS/GLONASS from the point of view of satellite on-board clocks, their system references, their national standards and ultimately UTC. Results are presented on the characterisation of GLONASS system and spacecraft clocks as compared to their Navstar GPS counterparts.
