Integrated space communities do not require trust

As space becomes increasingly contested, the terrestrial vulnerabilities of GPS will extend into orbit. The resulting inability to rely on GPS for time synchronisation on ground and in space will cause a fundamental shift in the approach to space networks. The AUDITS (AUtonomous DIstributed Time-signal In Space) project aims to design an autonomous, distributed, robust timing signal in space as an alternative method to GPS time synchronisation. Building upon prior work in consensus algorithms, this project has developed a Disruption-Tolerant Social-Dynamics inspired approach to consensus. This work is being adapted for time synchronisation and space networks which involve dynamic effects, time delays, and relativity effects.
