A six-accelerometer configuration is presented to compute the rotation
al and translational acceleration of a rigid body. This theoretical mi
nimum accelerometer configuration has as stable a mechanization equati
on as that of recent results of nine-accelerometer schemes. Associated
equations that can be used to work with the accelerometer location an
d orientation errors are also derived. For navigation application, the
novel design can be integrated with other sensors of complementary ch
aracteristics to enhance the performance.
