The Revolution™ AV (TNT4000) is a strap-down electronic compass designed specifically for commercial, industrial and military users requiring high accuracy, repeatability, and low power consumption in dynamic environments. The Revolution AV is the latest addition to True North’s family of Revolution electronic compasses that have an unparalleled reputation for quality and performance. An enhanced version of True NorthRevolution GS, the AV includes a full suite of precision, 3-axis, MEMS rotation rate, acceleration, and magnetic sensors and a dual-axis electrolytic tilt sensor (for the ultimate in near-level accuracy). All 11 sensor measurements are calibrated over a -50° to 110°C temperature range and aligned in three dimensions. In addition to azimuth output, all raw and calibrated measurements are available at up to 28 readings per second.
The AV’s sensor suite consists of the following: 3-axis angular rate gyros, 3-axisaccelerometer, 3-axis magnetometer, 2-axis liquid eTilt sensor
The recommended applications for the AV are manned and unmanned aerial and underwater vehicles, but it can also be appropriate for robotics, weather buoys, antenna positioning, platform stabilization, excavation machinery, and irrigation equipment. For cost sensitive applications, the rate gyros and eTilt are optional sensors that can be eliminated if not needed.
