The AR71 is a compact, multi-function NTP/PTP GPS-disciplined Time Server, measuring just 115 x 160 x 38 mm, and delivering precise time and frequency. This versatile unit integrates several features into a single box, including a Rubidium Frequency Standard, an internal 12-channel C/A code GPS receiver, and an external 1PPS input.

The Rubidium Standard operates as a local oscillator, phase-locked to either the GPS or an external input. All outputs are derived from the Rubidium Clock, ensuring continued accurate time and frequency even if GNSS or other input sources are lost.

An optional LAN interface board is available, supporting UDP/SNMP for management and NTP (Network Time Protocol). Alternatively, a version with Precision Time Protocol (PTP) or Time Of Day (TOD) in IRIG B format can be selected in place of the LAN board.

The AR71 can also be equipped with proprietary Anti-Jamming and Anti-Spoofing technology, offering enhanced protection in GPS-denied environments. For more information, please contact us directly.
