Abstract
Accurate synchronised time is key for many Earth- and space-based services: telecomms, sensor data, bank systems...
Currently, the primary source of this time data comes from GPS. But, the past years have shown GPS’ vulnerability to space weather and attacks which caused widespread disruptions.
With the number of satellites launched increasing exponentially and satellites becoming increasingly interconnected, satellite constellations are being re-imagined as Internet of Things (IoT) networks.
This shift in thinking towards IoT approaches enables a re-think of Time Synchronisation where current centralised methods are failing. Bringing Space and IoT together, this project presents a resilient, distributed, and space-based time synchronisation algorithm enabling satellites to synchronise despite of disruptions and without the need for an external reference source.
