A solid state compass and separate roll and pitch sensors are being used by the Latvian company, Hiberna Iceboards, to develop products for the latest extreme winter sport
 .
Each board has stainless steel blades at front and back and a mechanism that allows the user to steer it using body movements.
The company uses a solid state AOSI EX Compass 3A and AOSI tilt sensors from Variohm EuroSensor to determine the relationship between deck tilt and steering bridge rotation on a custom built evaluation rig. The Compass is also used on a 3D model as part of an animated software simulator for iceboard performance training.
For the deck tilt angle input, a roll sensor is attached directly to the deck. Bridge rotation, is determined either from the compass angle input located on the deck, or the pitch sensor attached to a vertical mast using a trigonometric formula to calculate the angle.
