An accelerometer includes an inertial platform maintaining an attitude in response
to a platform stabilizing controller signal and defining a spin axis and a reference
plane. An accelerometer, coupled to the inertial platform a distance from the spin
axis, defines a flex axis. The accelerometer generates an accelerometer signal
in response to acceleration of the accelerometer. A second accelerometer defines
a second flex axis, and is also coupled to the inertial platform a distance from
the spin axis. The second accelerometer generates a second accelerometer signal
in response to acceleration of the second accelerometer. A controller receives
the first accelerometer signal and the second accelerometer signal and generates
a linear acceleration signal in response to a sum of the first accelerometer signal
and the second accelerometer signal and generates an angular acceleration signal
from the difference. The controller further generates the platform stabilizing
controller signal in response to the first acceleration signal and the second acceleration signal.
