Abstract:
1. An accelerometer system comprising: an inertial platform defining a reference plane, a spin axis, and a linear acceleration axis, wherein said spin axis is within said reference plane and said linear acceleration axis is perpendicular to said reference plane, said inertial platform maintaining a minimized rotation in response to a platform stabilizing controller signal; a first accelerometer defining a first flex axis, said first accelerometer coupled to said inertial platform a first distance from said spin axis, said first accelerometer generating a first accelerometer signal in response to acceleration of said first accelerometer, a second accelerometer defining a second flex axis, said second accelerometer coupled to said inertial platform a second distance from said spin axis, said second accelerometer generating a second accelerometer signal in response to acceleration of said second accelerometer; and a controller receiving said first accelerometer signal and said second accelerometer signal, said controller generating a linear acceleration signal in response to a sum of said first accelerometer signal and said second accelerometer signal, said controller further generating said platform stabilizing controller signal in response to said first acceleration signal and said second acceleration signal.
