tiltbased
Tiltbased is a term used to describe a class of orientation estimation and attitude control methods that rely primarily on the tilt of a device relative to gravity to determine its orientation. In tiltbased approaches, pitch and roll are derived from the direction of the gravity vector as sensed by accelerometers, while yaw is treated as either unknown or handled separately with additional sensors or assumptions.
A typical tiltbased system fuses accelerometer data to estimate tilt angles relative to the vertical. Gyroscopes
Tiltbased methods cannot, on their own, determine heading (yaw). If the device experiences linear acceleration or
