Tactical System Timer

The Tactical System Timer (TST) is a self contained, high accuracy time base for environments that must maintain accurate time in harsh conditions. The unit synchronizes to a system GPS time through an NMEA compatible interface. For systems that require synchronization to a local clock, software can be used to command the unit to synchronize its internal clock using NTP over a network interface. The time is read using a time management library.
