AccuBeat has developed several versions of the AR51A07 for different applications. Please contact us for further information or for a fully customized solution to meet your specific needs.
The AR51A-07 unit is an industrial low profile GPS-Disciplined Rubidium Clock which offers an excellent stability and accuracy. The unit includes a Rubidium-Atomic-Standard which is phase-locked to the GPS or other external inputs. All outputs are 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 AR51A-07 includes Have Quick (ICD-GPS-060) input and output which is essential for secure radio communication applications. The unit can be remote controlled via MIL-STD-1553RT channel which is required in airborne applications.
The unit includes internal GPS receiver (C/A code) and have option to install P(Y) code SAASM GPS receiver (For more information contact factory).
The AR51A-07 is designed for demanding platforms such as airborne, helicopters, UAV’s, shipboard and ground mobile.
