Abstract
A system for synchronizing components of a downhole system includes: a source assembly including a source clock; an electromagnetic source associated with the source assembly and configured to emit an electromagnetic signal into an earth formation at a transmission time; a receiver assembly including a receiver clock; an electromagnetic receiver associated with the receiver clock and configured to detect the electromagnetic signal; and a processor configured to identify a receipt time of the electromagnetic signal based on the receiver clock and adjust the receiver clock by comparing the transmission time to the receipt time.
