Model 1095A/C Industrial GPS Clock (250 ns)
Model 1095A/C Industrial GPS Clock (250 ns)
Precision GPS timing source for industrial applications in a compact, rugged enclosure, suitable for indoor and outdoor applications.
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 <100ns 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 100ns resolution.
Choose between the external and internal antenna options to best suit your installation environment.
Model 1095A/C supports front panel options. See photos and Key Features tab below for more information.

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 to 12, 24 to 48 and 120 to 240 Vdc nominal input.
Programmable Pulse Output
Two programmable pulse outputs (5 Vdc), PPA and PPB.
Modes:
- 1 PPS
- Every 1 to 60,000 seconds, starts top of the minute
- Hourly at a specified offset
- Daily at a specified time of day
- One shot at a specified time of year
- 1 to 1000 PPS squarewave (PPB only)
- Aux IRIG Mode (PPB only)
Pulse duration is programmable from 0.01 to 600 seconds, except in one-shot mode, where the output is Low prior to the specified time and High thereafter.
Aux IRIG Mode provides an additional unmodulated IRIG-B signal on the PPB output.
Relay Contacts
One, Form C (SPDT) fail-safe, 0.3 A at 130 Vdc; jumper selectable to Fault, Out-of-lock, Programmable Pulse A (PPA), Programmable Pulse B (PPB), Stabilized, and Event-In functions. Fail-safe means the relay indicates "fault" or "unlocked" condition with power off.
