Claim:
1. In an unmanned aerial vehicle (“UAV”) having a plurality of sensors configured to perform autonomous flight operations, a method to synchronize the plurality of sensors in real time, the method comprising: performing a synchronization event; collecting with a first sensor of the plurality of sensors, a first signal corresponding to the synchronization event; detecting, with a first event detection component, the synchronization event as recorded in the first signal by the first sensor; determining, with the first event detection component, a first timestamp generated by the first sensor and corresponding to the detected synchronization event as recorded in first signal; collecting with a second sensor of the plurality of sensors, a second signal corresponding to the synchronization event; detecting, with a second event detection component, the synchronization event as recorded in the second signal by the second sensor; determining, with the second event detection component, a second timestamp generated by the second sensor and corresponding to the detected synchronization event as recorded in second signal; and adjusting, in real time during a first autonomous flight operation, the first timestamp such that the first signal and the second signal are temporally aligned.
