MR-600T

• 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.
