Feasibility of A Gyroscope-free Inertial Navigation System for Tracking Rigid Body Motion

In this report, the authors examine the feasibility of designing an accelerometer-based gyroscope-free inertial navigation system (INS) which uses only accelerometers to compute the linear and angular motions of a rigid body. A model for a micro-machined accelerometer is developed and the accelerometer output equation is derived to relate the linear and angular motions of a rigid body with respect to a fixed inertial frame. A sufficient condition is used to determine if a configuration of accelerometers is feasible. A configuration of six accelerometers is presented, and an algorithm is developed to compute both the angular and linear motions.
