True North Technologies Introduces Revolution AV Electronic Compass

(Maynard, MA) February 1, 2014 – True North Technologies is pleased to announce the introduction of the Revolution™ AV (TNT4000), 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 a time-tested reputation for quality and performance.

An enhanced version of the Revolution GS, the AV features a sensor suite which includes 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 are aligned in three dimensions. In addition to azimuth output, all raw and calibrated measurements are available at up to 28 readings per second. Rate gyro measurements rotated to the inertial frame of reference are also available. Independent complementary filters for pitch, roll, and azimuth can be adjusted for the user’s requirements.

The recommended applications for the AV are manned and unmanned aerial and underwater vehicles, robotics, weather buoys, antenna positioning, platform stabilization, excavation machinery, and irrigation equipment.

“Adding the Revolution AV is an important step forward for our electronic compass product line,” said David E. Pheifer, President of True North Technologies, “the implementation provides important new features: the three axis accelerometer and 3 axis gyros. These improvements are based on feedback that we received from our aerial and marine industry customers, and so far they have been very pleased with the results.“

True North Technologies develops and manufactures sensing products for marine, air, and landbased applications with a concentration in electronic compasses. The company was founded in 1993 and is located in historic Clock Tower Place in Maynard, MA, the original home of Digital Equipment Corporation.
