Yes, the TR-ORCA keeps its own time with a real time clock. This clock gets synced to UTC or computer time every time you connect to TRAC. Our real time buoy TR-FLOAT allows for real time wireless transmission of raw acoustic data, and also provides GPS information to TR-ORCA. It is possible to synchronize TR-ORCA time to GPS time. All recorded files are time stamped with the real time clock time.
