Description

Part number: 4.920x.00.00x
This instrument has a GPS receiver. It serves for the determination of position and time, the sun position is additionally calculated herefrom. Position, Time and sun position are transmitted serially.

The compact construction, easy mounting, and diverse options of data output are the basis for the use in several fields:
Building control system
Traffic engineering
Meteorology
Energy supply
Ecological monitoring
