Ocean Sonics - GPS Time Synchronization System

Ocean Sonics offers a Sync GPS Master which allows the icListen to be synchronized by receiving a GPS pulse per second (PPS). The system is very low power, small and can be mounted on a mast above water or on shore. Typical PPS can synchronize the seconds to a resolution of nanoseconds. However, the Sync GPS modulates the trailing edge of the PPS signal to encode the date & time as well. This guarantees that all instruments are fully synchronized to GPS time after two minutes. Comes with 20m cable.
