GPS receiver and antenna in a fully weather proof enclosure for time transfer application
The AQTIME MR-330T 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-330T 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.
Key Features:
- 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,¡Ketc. Time control of computer terminals connected to network
