MR-600T GPS Time Receiver
  • Quick start, 18 seconds warm start typical
  • Low power consumption (0.9W typical)
  • Wide supply voltages range (9~34VDC)

The AQTIME MR-600T is the integration of a timing GPS receiver and antenna in a compact/weather proof enclosure for time transfer application. It outputs UTC synchronized 1PPS with +/- 1 microseconds tolerance, which is close to an atomic clock in accuracy.

As a time transfer device, the AQTIME MR-600T is capable of operating with even 3(three) satellites after having a fix position with 3 or more satellites previously, so you can get precise time base anywhere on the Earth even under a very harsh environment where only one satellite is available.

  • UTC synchronized precise time base can be obtain anywhere on the earth at a relatively low cost
  • Ultra compact, fully weather-proof, easy to mount
  • Quick start, 18 seconds warm start typical
  • Continue to output time data with even one satellite tracked
  • Wide supply voltages range (9~34VDC)
  • Low power consumption (0.9W typical)

Applications:

  • Time Stamp Data Logger
  • Synchronization of radio base stations for cellular Phone, pagers,…etc.
  • Time control of computer terminals connected to network

MR600T 1PPS Specification

  • The signal is generated after the MR-600T power on and continues until power down.
  • The rising edge of the signal is synchronized to the start of each GPS second.
  • The signal is valid after the initial position fix has been calculated.
  • The accuracy of the one-pulse-per-second output is maintained only while the MR600T can compute a valid position fix.
  • The default pulse width is 1u second.
  • The pulse height is 3V.
  • The accuracy is +/- 1usec with respect to the GPS second.
