Abstract
An apparatus for detecting an angular rate of a moving body has first and second sensors each of which has a detection direction, the first and second acceleration sensors are mounted at fixed locations on a moving body so that the first and second acceleration sensors have substantially the same detection direction on a plane and a fixed distance therebetween in the detection direction, and the angular rate (.omega.) of the moving body is detected according to the following equation: ##EQU1## wherein .DELTA.G is an acceleration difference and R is the distance between the first and second acceleration sensors in the detection direction.
