This specification defines the requirements and test procedures for a digital accelerometer which utilizes a linear, single-axis, nongyroscopic acceleration sensor with a permanent magnet torquer (forcer) operated in a [ternary pulse mode, pulse-width modulation mode, analog mode with voltage to frequency converter, …]. The electronics are considered to be part of the accelerometer which produces a digital output proportional to sensed velocity changes. The digital accelerometer is hereafter… read more referred to as the accelerometer. With appropriate modifications, this specification may also be applied to force balance nonpendulous accelerometers. read less
