Embodiment Construction
[0053] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0054] (1) Installation scheme of inertial combined measurement device
[0055] combine figure 1 with figure 2 , the composition of the micro-miniature inertial integrated navigation parameter measurement device includes a regular hexahedron shell, nine accelerometers are installed at the four vertices of the three intersecting faces of the regular hexahedron shell, and each face has three accelerometers , a surface without an accelerometer is the backplane of the power module, and the backplane of the power module is superposed with a PC104 main board, an AD conversion board, a digital compass and a GPS receiving board, and the analog information output by each accelerometer is transformed by the A / D conversion board. After converting into a digital signal, input it to PC104 to preprocess the sampling data, and then use the calculation method of angular motion...
