Ariane 6 Launches: Impacts for Galileo G2

Ariane 6’s inaugural rocket launch took place from Europe’s Spaceport in French Guiana at 16:00 local time on 9 July. It has taken over from Ariane 5, featuring a modular design that can launch missions from low-Earth orbit and into deep space. Galileo Second Generation (G2) satellites are projected to join the constellation in 2026 with the Ariane 6 launcher. G2 satellites will use electric propulsion and host a more powerful navigation antenna, better atomic clocks and fully digital payloads.

altGNSS GEO SecureTime: VIAVI’s New Solution for Improved Timing

For applications that require accurate UTC timing, the options are pretty limited. Yes, GPS provides timing, but it has its vulnerabilities. Iridium STL is the only other option with global coverage, but it has its drawbacks, too, as it’s restricted to L1 and can’t be leveraged for every application.

Weekend Read: The Tale of Two Clocks

JILA, established by NIST and the University of Colorado Boulder, has played a pivotal role in advancing precision timekeeping through optical atomic clocks. These devices achieve extraordinary time measurement accuracy by utilizing the fundamental properties of atoms. Despite their advancements, the precision of these clocks is limited by quantum projection noise (QPN), arising from the quantum nature of the atoms.
