A configurable sensor module for determining position and acceleration

The PCAN-GPS Pro FD is a configurable sensor module for detecting position, orientation, and acceleration. It has a magnetic field sensor, an acceleration sensor, a gyroscope, and a satellite receiver that allows update rates of up to 25 Hz. The sensor data is transmitted via CAN or CAN FD. The connection to the CAN bus is designed with two interconnected LEMO circular connectors for integration into measuring chains. Thanks to the robust housing, the module can also be used under tough conditions.

The device parameters, capturing of sensor data, and CAN message transmission of the PCAN-GPS Pro FD can be configured via the USB port using the Windows® software included in the scope of supply. Afterwards, the module runs as an independent CAN node.
