Embodiment
[0049] The present invention is described in detail by taking the design of an inertial measurement component for the strapdown inertial navigation component of a certain missile-borne strapdown guidance system as an example. The maximum external dimension of the inertial measurement component is required to be Φ150mmx60mm; the maximum angular velocity along the roll axis of the missile is 1000° / s; the maximum acceleration rate along the roll axis of the missile is 15g; The maximum acceleration is 8g; if a gyro is selected, its maximum size is Φ68mmx20mm, and its maximum dynamic range is 600° / s; a certain accelerometer is selected, its maximum size is 36mmx18mmx12mm, and its maximum dynamic range is 10g.
