Employing Chip-Scale Atomic Clocks (CSAC) to sustain airborne swarm coordination during GPS jamming.
Modern electronic warfare systems weaponize GNSS denial. Aircraft relying on GPS 1PPS signals for clock calibration suffer fatal timing drift within seconds. Integrating cesium vapor CSAC units limits drift to less than 1 microsecond over 24 hours of total satellite blackout.
Swarm aircraft exchange two-way time-transfer optical packets over line-of-sight laser transceivers, using statistical Kalman filters to average clock drift across all nodes and maintain absolute temporal coherence.
