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).
