METHOD OF MEASURING LINEAR ACCELERATION Russian patent published in 2009 - IPC G01P15/13 

FIELD: physics; measurement.

SUBSTANCE: invention relates to measurement techniques, particularly to measurement of linear acceleration in inertial navigation systems of aeroplanes, rockets, ships, spacecraft and other mobile objects. Three technical characteristics are simultaneously obtained: conversion coefficient, zero shift and relative error value Δa₀/a_max, which characterises stability of the measured error and "ГХ" stability at the same time. If conversion coefficient is stable K_a=const, and acceleration a, is determined using formula N_i=K_a(a_i+Δa_0i), presence of which is sufficient for selecting inertial sensors of initial information and predicting expected errors of the system for controlling movement and navigation of mobile objects, including carrier rockets and spacecraft.

EFFECT: more accurate measurement of acceleration in a given range using a device based on a self excited accelerometre.
