GPS500 GPS Time Code Generator

The GPS500 is a precision IRIG-B or SMPTE time code generator. It provides a source of very stable time code, referencing time and date information from atomic clocks in the GPS satellite constellation.

It extracts timing reference from these signals and generates time code that is synchronized within less than 10 microseconds of UTC (Universal Coordinated Time). Learn more about Master Clocks.

SpecificationsGPS500 GPS Time Code Generator

  • Accuracy: SMPTE output accuracy of ± 20 microseconds, when synchronized
  • Accuracy: IRIG-B0 (DCLS/PWM) output accuracy of ± 90 microseconds, when synchronized
  • Accuracy: IRIG-B1 (AM) output accuracy of ± 1.4 milliseconds, when synchronized
  • Accuracy: PPS output accuracy of ± 60 nanoseconds, when synchronized
  • Should the GPS500 lose GPS signal it will revert to an internal TCXO oscillator and maintain an accuracy of ± 1 minute per year. The PPS output is synchronized to the internal TCXO oscillator.

  • SMPTE, EBU:30, 25 or 24fps
  • IRIG-B: 1 kHz modulated, level - 5 Vpp
  • IRIG-B: unmodulated, single ended 5 V
  • PPS: 5 V-TTL, accuracy ± 60 nanoseconds (when synchronized to GPS)
  • PPS: Pulse width configurable via switch from ~200 ms to ~1 ms
  • Serial output via RS-232/RS-485 NMEA Kinemetrics/Truetime protocol
  • Date encoded references (IRIG 1344 and SMPTE Leitch date format or 309M)
