Rugged, accurate and economical, the 1095A/C GPS Industrial Clock Module from Arbiter Systems®, Inc. is the engineer's choice when flexibility, precision and physical durability are required.

The 1095A/C precision time clock is a low cost unit capable of driving common timing signals such as IRIG-B, 1PPS and RS-232 serial time codes, with < ± 100 ns typical accuracy. The compact, rugged enclosure can be mounted in multiple ways, making installation fast and secure. Ideal for outdoor applications, the 1095A/C is capable of performing when other units fail, operating between - 40 °C and 85 °C. Four configurable outputs support substantial drive capability, allowing a single unit to drive multiple loads in parallel.

The 1095A/C maintains the real-time clock, almanac and ephemeris data powered by a back up battery in the case of power loss, reconnecting to the satellite signal in as little as 15 seconds. The built in Event Capture function means the unit records key events related to data received from the input options, with 100 ns resolution.

Choose between the standard internal and optional external antenna to best suit your installation environment.

Model 1095A/C supports front panel options. See photos and Key Features tab below for more information.

  • Internal GPS antenna
  • Rugged case for outdoor or demanding environments
  • Accuracy < ± 100 ns typical; < ± 250 ns worst case
  • Four terminal strip connector outputs, three high drive, one analog
  • Two RS-232 ports
  • One Form C (SPDT) fail-safe relay
  • Battery or power source operated

Versions A/C offer various interface options (see photos):

  • External GPS antenna
  • 1095A utilizes an opaque cover, optionally may be ordered with a "smoked' cover
  • 1095C includes a "smoked" cover with four LEDs to monitor operating status and a large seven-segment LED time display

Receiver Characteristics

Timing Accuracy

Accuracy Note

Specifications apply at the 1 PPS output, IRIG-B Level-Shift and Programmable Pulse outputs, with US Department of Defense Selective Availability (SA), as of date of publication.

Accuracy UTC/USNO

± 250 ns peak; < ± 100 ns typical (SA off)

Position Accuracy

10 meters, rms, 90 % confidence

Satellite Tracking

Twelve (12) channel, C/A code (1575.42 MHz). Receiver simultaneously tracks up to twelve satellites.

Acquisition

  • 150 seconds typical, cold start
  • 15 minutes, 90 % confidence, cold start
  • 40 seconds, with almanac less than 1 month old
  • 15 seconds, with ephemeris less than 4 hours old

I/O Configuration

Output Connectors

Four Total: three high-drive 5 Vdc (250 mA at > 4 V), one analog (4.5 Vpp), terminal strip connectors.

Output Signals

Output 1: Programmable Pulse A
Output 2: IRIG-B00x level-shift
Output 3: Programmable Pulse B
Output 4: Modulated IRIG-B

Event Inputs

One opto-isolated event capture input with 100 ns resolution, terminal strip inputs for 5 Vdc to 12 Vdc, 24 Vdc to 48 Vdc, and 120 Vdc to 240 Vdc nominal input.

Programmable Pulse Output

Two programmable pulse outputs (5 Vdc), PPA and PPB.

Modes:
