Time Transfer GPS Marine Receiver

Take advantage of GPS solution by incorporating VP-200T GPS Marine Receiver/Antenna into your existing marine navigational equipments

Overview

VP-200T 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 +/- 100 nanoseconds tolerance, which is close to an atomic clock in accuracy.

As a time transfer device, VP-200T 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 (8~40VDC), low power consumption (0.9W typical)

1 PPS OUTPUT

• Output signal level: TTL@3.3V(4.8v optional)
• Output data format: NMEA 0183
• Accuracy: +/- 1 m second (2DRMS) to UTC
• Accuracy: +/- 100 nano second(2DRMS) to UTC via software adjustment

Applications

• Time Stamp Data Logger
• Synchronization of radio base stations for cellular phone, pagers, and so on.
• Time control of computer terminals connected to network
