1093A/B/C GPS Satellite Controlled Clock
OEM код:
1093A/B/C
Код на производителя:
1093A/B/C
Производител:
Arbiter Systems
Arbiter Systems
Описание:
  • Accuracy <500 ns typical
  • Unmodulated IRIG-B and 1 PPS included, modulated IRIG-B optional
  • Options include an internal NTP server, High Drive IRIG-B outputs, One Form C (SPDT) fail-safe locked relay, and Power System Time, Frequency and Phase Monitor

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

  • 1093A supports four LEDs for monitoring operating status.
  • 1093B adds to the LEDs an LCD display and keypad, providing easy access to setup and system status information.
  • 1093C includes both the operating status LEDs, the LCD display and keypad, and includes a large LED time display.

Спецификация:

Receiver Characteristics

Timing Accuracy

Accuracy Note

Specifications apply at the 1 PPS output, in the presence of Selective Availability (SA), as of date of publication

Accuracy UTC/USNO

±500ns peak

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. Results from all tracked satellites are averaged in Position-Hold Mode or, with Position-Hold Mode off, using least-squares estimation.

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
  • The GPS Data Backup Battery is now included in the Model 1093s. This feature improves acquisition time to as little as 15 seconds after a brief power loss by supplying constant power to the real-time clock and RAM in the GPS receiver module.

I/O Configuration

Output Connectors

Two standard: one IRIG-B Unmodulated and one 1 PPS; Type: bus driver, 5 V CMOS; 10 ohms source impedance; ±75 mA drive capability; pluggable terminal strip.
Open-drain FET drivers (400 V, 220 mA, 1 W power dissipation) can also be fitted; contact tech support.

Event Inputs

One event timer channel with 1 µs resolution is standard. This function may be driven by the start bit of a received character on the serial port, or (by internal connection) an external 5 V CMOS/TTL signal at one of the terminal strip connectors.

Programmable Pulse Output

One programmable output pulse (by a jumper connection) that may be output on a terminal strip connector or the AUX OUT pin on either RS-232 Port.
Four modes:

  • 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

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.

Setup
  • Local time offset
  • Output code select: Local/UTC
  • Daylight Saving Time (Set Summer Time): Off/On/Auto USA/Auto EUR/Auto CUS
  • Backlight control: On/Off/Auto
  • Event input: Event/1 PPS
  • Programmable Pulse setup
  • Antenna delay
  • Out of lock time: 1 to 99 minute(s), Off, or Zero Delay
  • Auto-Survey: On/Off, Survey duration
  • Position Hold: On/Off, Position Auto/Manual
  • Option Configuration and Setup
  • Serial port: RS-232

System

RS-232

1200 to 19,200 baud; 7 or 8 data bits; 1 or 2 stop bits; even/odd/no parity

Second RS-232 port available (1093opt19)
Connector: Male 9-pin D-sub (TXD, RXD)

RS-422/485

Optional driver can also be fitted (1093opt94)

Broadcast modes
  • Standard ASCII (IRIG-J)
  • Extended ASCII
  • ASCII with Time Quality
  • ASCII with Time Quality and Year
  • Vorne large-display time
  • Status/Alarm
  • Event data
Connector

Male 9-pin D-sub (TXD, RXD, AUX IN, AUX OUT)

AUX OUT can provide programmable pulse function at RS-232 levels
