AR15A-09 Image

The AR15A-09 from AccuBeat is a compact military grade GPS-disciplined Rubidium Clock which offers excellent stability and accuracy. It includes a Rubidium Atomic Standard, which is phase locked to an external disciplining source such as GPS or another external input. All outputs are derived from the Rubidium Atomic Standard and maintain highly accurate time and frequency even when GPS reception is interrupted. It can be synchronized from 3 independent inputs: internal GPS, external GPS, and other external independent accurate timing systems. The input synchronization source can be manually selected by the user or set automatically.

The unit includes multiple Time of Day (TOD) inputs and outputs, several Have Quick (ICD-GPS-060) Time Code outputs, in addition to more than 20 1PPS outputs (PTTI ICD-GPS-060, TTL and RS-422 formats) for accurate timing making it an essential unit for secure radio communication applications amongst other possibilities. The standard unit also includes Have Quick (ICD-GPS-060) Time Code input for initial time loading as well as 1PPS input for timing synchronization when a GPS signal is not available.

The AR15A-09 is available in an enclosure that measures 175 x 132 x 56 mm and allows communication via the CLI (Command Line Interface) using RS-232 or RS-422 and the CLI output provides Time, Navigation, and status data. It is designed for demanding military platforms such as fighter aircraft, helicopters, UAV’s, shipborne, submarine, and mobile military land platforms. The unit is designed for quick installation on a vibration tray or hard mounted with fixing screws.
