AR71 Compact NTP/PTP Time Server 

AccuBeat’s AR71 is a compact NTP/PTP multi-function GPS disciplined Time Sever measuring just 115 x 160 x 38 mm and providing accurate time & frequency. The AR71 incorporates numerous features into a single box, including a Rubidium Frequency Standard, an internal C/A code 12 channels GPS receiver and external 1PPS input.


The Rubidium Standard functions as a local oscillator and is phase-locked to the GPS or to external input. All outputs are derived from the Rubidium Clock, which maintains accurate time and frequency when the GNSS or other inputs are interrupted.


The unit includes an optional LAN interface board which supports UDP/SNMP for management and for NTP (Network Time Protocol). A version supporting Precision-Time Protocol (PTP) or TOD in IRIG B format is also available instead of the LAN board.

 

AR71 can be supplied with AccuBeat’s proprietary Anti-Jamming and Anti-Spoofing technology providing additional protection in cases of GPS denial. For further details, please contact us directly.
