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.
