Accurate Time & Frequency Ruggedized System
AccuBeat’s AR77 is a fully ruggedized mil-spec multi-function GPS Disciplined Time Server which provides accurate time & frequency. The AR77 incorporates numerous features into a single box including a Rubidium Frequency Standard, an internal C/A code 12 channels GPS receiver or (optional) P(Y) code GPS receiver* and can receive an input from an external 1PPS/frequency.
The various options of the unit include a variety of different frequencies and several Time Codes outputs such as IRIG, Have Quick NMEA etc. The Rubidium Standard functions as a local oscillator and is phase-locked to the GPS or to external inputs. All outputs are derived from the Rubidium Clock, which maintains accurate time and frequency when GPS or other inputs are interrupted or lost.
