The invention discloses a table body structure for installing an inertia instrument and an inertia measurement device. The table body structure comprises: a middle body which is a straight quadrangular prism structure; four bosses by taking the middle body as the center, respectively extending outwards from four longitudinally-extending edges of the middle body and forming a cross-shaped structurewith the middle body; containing spaces formed between every two bosses and the middle body, wherein the four containing spaces are arranged in a cross shape, and the inertia instrument installationpositions are arranged on the four side faces, corresponding to the four containing spaces respectively, of the middle body, the top face of the middle body and the bottom face of the middle body. Thecross-shaped table body structure is adopted, and compact installation of an inertia instrument on the table body structure and miniaturization and light weight design of the table body structure areachieved under the condition that the space arrangement requirements of the X axis, the Y axis and the Z axis of the inertia instrument and the measurement precision are met; and due to the four bosses of the cross-shaped structure, the table body structure can be conveniently installed on an external part, and the installation difficulty of the table body structure is reduced.
Description
technical field [0001] The invention relates to a table body structure and an inertial measurement device for installing an inertial instrument, belonging to the technical field of navigation, guidance and control, used for measuring the acceleration and rotational angular rate of a carrier, and suitable for a position attitude system and a strapdown inertial navigation system . Background technique [0002] The inertial navigation system relies on its own inertial sensitive components for navigation, and does not rely on any external information to measure navigation parameters. Therefore, it is not subject to natural or artificial interference, has good concealment, and is a completely autonomous navigation system. Modern missiles, satellites, spacecraft and other carriers have put forward higher and higher requirements for the reliability and accuracy of the inertial navigation system, because it not only directly reflects the quality index of the inertial navigation syst...
