IMU-GPS Logger

The IMU-GPS data logger includes a set of motion sensors as well as a Global Positioning System (GPS) feature. The set of motion sensors include a 3-axis accelerometer, a 3-axis gyroscope, a 3-axis magnetometer, and a precision barometric pressure sensor. The GPS feature adds location data at samples rates up to 10 Hz. Combined, the motion sensors and GPS data provides complete orientation and location information. Time stamps are disciplined to GPS time.

GCDC designs and asssembles data loggers "in-house" so we can customize the IMU-GPS product to fit specific needs. The pictured IMU-GPS (above) is enclosed in a 3D printed box measuring 3x1.8x0.8 inches. However, the logger can be easily repackaged into other configurations to accommodate customer requirements. For example, this logger was packaged into a waterproof enclosure with a large 5Ah battery. This allowed long term activity monitoring of cattle (see Applications below).
