Introducing the Revolution AV+, a unique combination magnetic compass and IMU with advanced vibration and sensor fault detection. It features 11 sensors electronically aligned in three dimensions and calibrated over a ‑50°C to 110°C temperature range. It is designed specifically for commercial, industrial and military users requiring high accuracy, repeatability, and low power consumption in dynamic environments. The Revolution AV+ is the newest addition to True North’s family of Revolution compasses that have an unparalleled reputation for quality and performance.
The Revolution AV+ can be used as either an electronic compass or an IMU, or both. In compass mode, a rich set of ASCII output strings that contain heading, pitch, roll, and diagnostic measurements are available for RS232 or RS485 output at up to 115,200 baud. IMU mode data is contained in a binary packet that can be streamed at 50Hz or captured by request. Operating mode can be changed by command input.
Built in diagnostic and test features ensure that all sensors are operating properly. Power-up and/or soft-reset electrostatic tests can be selected to verify accelerometer and gyro operation at startup. Run-time monitoring of ambient temperature, sensor voltage levels, electrolytic sensor impedance, and magnetometer set-reset offsets provides a high degree of confidence in reported measurements.
True North offers a development kit that includes the compass, cable, and software. The Revolution AV+ is covered by a full one-year warranty for workmanship.
