Revolution GSIf your compass application involves vibration, acceleration, uneven terrain, or rough seas, you will find the True North Revolution GS electronic compass to be an uncompromising solution that will outperform rival products costing considerably more. The GS provides remarkably accurate heading, pitch, and roll in dynamic conditions. It all starts with a precision 3-axis solid-state magnetometer. Two angular rate gyros independently stabilize pitch and roll. They augment a dual-axis electrolytic tilt sensor that provides precise tilt measurements in static environments. Two sets of independent filters, one set for pitch and one for roll, combine gyro and electrolytic sensor measurements to provide the best available tilt measurements.

The recommended applications for the GS are manned and unmanned vehicles, robotics, weather buoys, antenna positioning, platform stabilization, marine navigation, excavation machinery, and irrigation equipment.

True North offers a development kit that includes the compass, cable, and software. The Revolution GS is covered by a full one-year warranty for workmanship.
