If your application involves vibration, acceleration, movement over 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 unstable conditions. It uses vibration-rejection rate gyros to stabilize accelerometer measurements. False short-term indications of pitch and roll rotations are eliminated by using the gyro signals instead of accelerometer readings at high frequencies.
The GS+ is a member of our high performance AV+ family. It uses the same RoHS compliant PC assemblies and firmware. Circuit boards are conformal coated to withstand rugged environments and to protect the non-magnetic silver PCB finish required for accurate sensing of earth’s magnetic field.
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.
