---------------------------------------------------------------------------------------------------------------------------------------

VP-88T is the integration of a timing GPS receiver and antenna in a compact/weatherproof enclosure for time transfer application. It outputs UTC synchronized 1pps pulse with 50 nanoseconds tolerance, which is close to an atomic clock in accuracy.As a time transfer device, the VP-88T is capable of operating with even 3(three) satellites after having a fix position, so you can get precise time base anywhere on the Earth even under a very harsh environment.

Key Feature:

l 16 independent tracking channel

l Excellent noise immunity

l Very Fast TTFF

l Sensitivity: -150dBm(Tracking)

l 2 NMEA-0183 output

l User selectable baud rate

l Easy installation / operation

l Dual RS-232 for NMEA

l One TTL for 1PPS output

l DGPS and full SBAS(WASS,EGNOS) support

Possible Application:

l Time Stamp Data Logger

l Synchronization of radio base stations for cellular phone, pagers, and so on.

l Time control of computer terminals connected to network

l Master clock reference system for test and measurement requirements

l Telecommunications time & frequency primary clock reference system

l Time control of computer network terminals

l Range instrumentation systems

l Astronomic observatories - timing records of celestial events and simultaneous observations at distant locations.
