A new marine compass

US company True North Technologies has launched its 'Revolution GS' electronic compass.

The company recommends the 'GS' for marine navigation, manned and unmanned vehicles, robotics, weather buoys, antenna positioning, platform stabilisation, excavation machinery and irrigation equipment.

The compass uses a precision 3-axis solid-state magnetometer plus 2 angular rate gyros independently monitoring pitch and roll, augmented by 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.

Stated performance includes:
- Dynamic: heading within 3° typical for rates < 150 °/sec, pitch and roll within 1° for rates < 150 °/sec
- Static: heading within 0.5°, tilt within 0.2°
- Operating Range: ±40° pitch and roll, ±80° dip angle range, temp -25° to 85°C, local hard iron to ±1 Gauss

True North explain that the Revolution GS is compatible with their previous Revolution and Revolution 2X compasses - the magnetic calibration procedure required on installation is identical, as are cabling and power requirements.
