Sensor module

Position and orientation valuation

Peak-System’s PCAN-GPS is a programmable sensor module for position and orientation determination. It has a satellite receiver, a magnetic field sensor, an accelerometer, and a gyroscope.

THE SAMPLED DATA CAN BE TRANSMITTED on a CAN network and logged on the internal memory card. The module has a single high-speed CAN channel which supports bit-rates from 40 kbit/s up to 1 Mbit/s. Wake-up is possible by the CAN network, or by a separate input.

On delivery, the PCAN-GPS is provided with a demo firmware that transmits the raw data of the sensors periodically on the CAN network. The source code of the demo firmware as well as further programming examples are included in the scope of supply. New firmware can be loaded via the CAN interface. To transfer the firmware via CAN, a Peak CAN interface is required.

The data is processed by a micro-controller of the NXP LPC4000 series. Using the supplied library and the Yagarto GNU ARM toolchain (contains the GNU Compiler Collection GCC for C and C++), custom firmware can be created and then transferred to the module via CAN. This gives a whole range of options for manipulation, evaluation, filtering, and routing of the data traffic.

The card also comes with a Bosch BMC050 electronic three-axis magnetic field sensor and three-axis accelerometer, a L3GD20 gyroscope from STMicroelectronics, as well as a u-blox MAX-7W receiver for navigation satellites (GPS, Galileo, GLONASS, QZSS, and SBAS). To receive a satellite signal, an external antenna must be connected to the SMA socket. Both passive and active antennas are suitable. An active antenna is included. The card offers LEDs for status signaling, needs a power supply in the range of 8 VDC to 30 VDC, and features a microSD memory card slot.
