Abstract
Determining an object's inclination fixed reference frame relative to a gravity field includes supplying circularly disposed accelerometers rigidly linked by the object and measuring in non-collinear directions. A radius linking it to the circle's center defines an accelerometer's measurement direction. The accelerometers measure components of the field along the measurement directions to provide measurement values. Then, a matrix equation is solved to obtain the object's inclination relative to the reference frame.
