DGNSS
The CEIA DGNSS is a Differential Global Navigation Satellite System for use with CEIA DSMD® Metal Detectors, allowing the combined recording of differential georeferencing data, with centrimetic precision, and metal detector output signal strength on an embedded memory. Upon search operations completion, all recorded data can be exported to a PC system for postprocessing, map overlaying, screen visualization and mass storage recording. The CEIA DGNSS is a differential global satellite navigation system designed for use in combination with the CEIA DSMD® metal detector.
The system consists of a fixed DGNSS/BASE unit and a mobile DGNSS/ROVER1 unit for each metal detector. At the end of the search operations the DSMD® unit enables the recordings of the differential positioning data, with centimetre precision, and the alarm levels of the metal detector to be extracted on a USB stick or on a PC.
DGNSS/BASE : The DGNSS/BASE, installed in a fixed position in the same search area, receives the signals sent by the visible satellites, calculates the coordinates of the relative position and transmits them, by RF connection in broadcast mode, to the DGNSS/ROVER1 unit.
DGNSS/ROVER1 : The DGNSS/ROVER1 receives the signals sent by visible satellites and the coordinates transmitted using RF connection from the DGNSS/BASE and calculates, with respect to the latter, its relative position with centimetre accuracy.
