Description
The AR51A-09 unit is a compact GPS-Disciplined Rubidium Clock, which offers an excellent stability and accuracy. The unit includes a
Rubidium-Atomic-Standard, which is phase-locked to the disciplining source (like GPS or other external inputs).
All outputs are derived from the Rubidium-Atomic-Standard and maintain highly accurate Ɵme and frequency even when GPS recepƟon
interrupted.
The AR51A-09 includes Time of Day (TOD) inputs and outputs. The standard unit include several Have Quick (ICD-GPS-060) Time Code
outputs, followed by several (more than 20) 1PPS outputs (PTTI ICD-GPS-060, TTL and RS-422 formats) for accurate ming which is essen al
for secure radio communica on applica ons. The standard unit includes also Have Quick (ICD-GPS-060) Time Code input for ini al me
loading followed by 1PPS input for the 1PPS ming synchroniza on, when the GPS signal is not available. The communica on with the unit is
the CLI (Command Line Interface) by RS-232 or RS-422. The CLI outputs provides Time, Naviga on and status data. The unit can be configured
by CLI input channel.
Other Time of Day formats are available as an op on like NMEA, IRIG B, NTP or PTP.
The AR51A-09 can be synchronized from 3 independent inputs: internal GPS, external GPS and other external independent accurate ming
systems. The input synchroniza on source is selected manually by user or automa cally.
Standard op on of the unit is LAN interface, which include NTP (Network Time Protocol), and Monitor & Control by UDP or by SNMP.
