MR-600T
Produkt-Beschreibung
- 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.
Produkt-Eigenschaft
- 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.
