Features

Description

The AR-51-07 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 me and frequency even when GPS recep on is interrupted. When disciplined to GPS the unit

provides me accuracy of < 20ns RMS and frequency accuracy be er than 2E-12.

The AR-51-07 includes Have Quick (ICD-GPS-060) input and output which is essen al for secure radio communica on applica ons. The unit

can be remote controlled via MIL-STD-1553RT channel which is required in airborne applica ons.

The unit includes internal GPS receiver (C/A code) and have op on to install P(Y) code SAASM GPS receiver (For more informa on contact

factory).

The AR-51-07 is designed for demanding pla orms such as airborne, helicopters, UAV’s, shipboard and ground mobile.
