Trimble Outdoors AcutimeTM2000 Synchronization Kit manual Overdetermined Clock Mode

5 System Operation

Overdetermined Clock Mode

Overdetermined Clock Mode is used only in stationary timing applications. This is Acutime 2000's default mode. After the Acutime 2000 self-surveys its static reference position, it automatically switches to Overdetermined Clock Mode and determines the clock solution. The timing solution is qualified by a T-RAIM algorithm, which automatically detects and rejects faulty satellites from the solution.

In this mode, the Acutime 2000 does not navigate or update positions and velocities, but maintains the PPS output, solving only for the receiver clock error (bias) and error rate (bias rate).
