Accelerometers used in inertial navigation measure the force required to keep a proof mass stationary with respect to its enclosure, which is called specific force to distinguish it from unsensed gravitational accelerations. Accelerometer designs differ in how that force is measured, and how that force is distributed. Examples of these different design approaches are given in the following text.
