Embodiment Construction
[0021] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:
[0022] A rotary data synchronization strategy for strapdown inertial navigation, such as figure 1 shown, including the following steps:
[0023] Step 1. The inertial navigation equipment is powered on, initialized and performs rough alignment. The specific method is:
[0024] (1) The inertial navigation equipment is powered on, and the two rotating shafts rotate to their respective zero positions according to the preset control command;
[0025] (2) Staple the initial position, complete the rough alignment process according to the preset rough alignment scheme, and obtain the rough alignment result.
[0026] Step 2. Two-axis rotation modulation fine alignment and data synchronization adjustment.
[0027] (1) The inertial navigation enters the stage of fine alignment, and begins to rotate periodically with eight or sixteen sequences;
[0028] (2...
