Apparatus Using Atomic Clocks TRIZ Cases
- GNSS/INS Navigation Assurance with CSAC Kalman Filtering
By comparing GNSS and CSAC 1PPS phases, a Kalman filter estimates clock errors to detect spoofing and maintain stable UTC time.
- Atomic Clock Holdover With Predictive Frequency Drift Compensation
During holdover without an external reference, predictive analysis of clock and environment data anticipates frequency drift to preserve accurate timekeeping.
