AR51-07 Low Profile, MIL-Spec, GPS Disciplined, Time and Frequency Unit

AccuBeat’s AR51-07 unit is a low profile GPS Disciplined Rubidium Clock which offers excellent stability and accuracy. The unit includes a Rubidium Atomic Standard which is phase-locked to the GPS or to other external inputs. All outputs are then derived from the Rubidium Atomic Standard and maintain highly accurate time and frequency even when GPS reception is interrupted. When disciplined to GPS the unit provides time accuracy of < 20ns RMS and frequency accuracy better than 2E-12.

​

The AR51-07 includes Have Quick (ICD-GPS-060) input and output which is essential for secure radio communication applications. The unit can be controlled remotely via MIL-STD-1553RT channel making it suitable for airborne applications as well.  AR51-07 includes an internal C/A code GPS receiver and has the option to install a P(Y) code SAASM GPS receiver instead (needs to be supplied by the customer).

​
