Absolute Position Measurement for AGV's

The RFM2.1 is an absolute measurement system based on transponder technology (RFID) and is especially designed for positioning of automated guided vehicles (AGV) in a heavy duty environment with up to 10 mm accuracy.

The system uses a 134 kHz. programmable transponder, which is programmed with its exact position related to a chosen reference point. The transponder will be installed easily in the ground and works battery-less. The system charges a transponder within its measurement range, reads out its code and determines the position of the transponder under the system.

The absolute position of the transponder and the relative position of the transponder under the system result in an exact position of the RFM2.1 system, which will be send to the navigation computer.

BTG is worldwide the leading company for AGV position measurement in the automated Ports.
