Suitecase

Accurate Time & Frequency Ruggedized System

AccuBeat’s AR50-05 is a portable case designed to disseminate frequency and time (TOD – Time of Day) especially in cases of GPS jamming and spoofing. The portable case includes one of AccuBeat’s GPS-Disciplined Rubidium Atomic Clock as well as a backup battery, ruggedized tablet and a set of auxiliary cables for dissemination of the signals. The AR50-05 loads accurate time & frequency from an external source, maintains it on the go and disseminates the accurate time & frequency to the destination clock.

The unit works from 110/220 VAC as well as 12/28 VDC power and can be easily operated by a soldier or other personnel with minimal training. The ruggedized tablet allows simple and foolproof operation of the equipment and the rechargeable battery allows transportation of the unit in a vehicle while still connecting it to power as well as operation of the unit in the field. A customer with several AR50-05 portable calibration cases can store them in the DS5000 Docking Station specially designed for this purpose.
