Time synchronization of bottom hole assembly components via powerline communication

A system for performing a time synchronization among electronic components within a bottom hole assembly (BHA), the system comprising:

• a first electronic component within the BHA to generate a signal;
• a first transceiver to receive the signal from the first BHA component and convert the signal into a digital signal;
• a field programmable gate array (FPGA) to send a synchronization message, the synchronization message being a modified synchronization message generated by modifying a preamble of the digital signal, responsive to the FPGA operating in a preamble modifier mode, by adding additional symbols to the preamble of the digital signal to mark a moment in time;
• a second transceiver to generate a physical waveform of the synchronization message;
• a powerline interface to transmit the physical waveform over a powerline;
• and
• a second electronic component within the BHA to receive the physical waveform via the powerline and to perform the time synchronization by detecting the physical waveform, determining a local time drift compared to the moment in time, and adjusting a local clock to account for the local time drift.
