AR51-05 Image

AccuBeat’s AR51-05 incorporates numerous features into a single box, including a Rubidium Standard, an internal GPS receiver, a Rubidium-GPS DPLL (disciplining) circuit, time codes and multiple outputs. The Rubidium clock can be phase locked to the GPS or to an alternative external input source. All outputs are derived from the Rubidium clock which maintains time and frequency when GPS or other inputs are interrupted.


The AR51-05 has been fully qualified for operation in harsh stressed environments on ground mobile, airborne, UAVs, fighter aircraft, Helicopter and ship-borne platforms. AR51-05 can be supplied with AccuBeat’s proprietary Anti-Jamming and Anti-Spoofing technology providing additional protection in cases of GPS denial.
