Claim 3:
4. The launching method according to claim 3, wherein obtaining the geomagnetic triaxial correction parameters based on the new geomagnetic triaxial extreme value data comprises:
Obtaining the magnetic field correction factor according to the following formulas:

X-axis magnetic field correction factor: Kx=(Xmax×Xmax+2×Xmin)/(2×Xmax)−Xmin/2−Xmin/Xmax;

Xmax represents the maximum value of the geomagnetic triaxial extreme value in the X-axis direction, and Xmin represents the minimum value of the geomagnetic triaxial extreme value in the X-axis direction;

Y-axis magnetic field correction factor: Ky=(Ymax×Ymax+2×Ymin)/(2×Ymax)−Ymin/2−Ymin/Ymax;

Ymax represents the maximum value of the geomagnetic triaxial extreme value in the Y-axis direction, and Ymin represents the minimum value of the geomagnetic triaxial extreme value in the Y-axis direction;

Z-axis magnetic field correction factor: Kz=(Zmax×Zmax+2×Zmin)/(2×Zmax)−Zmin/2−Zmin/Zmax;

Zmax represents the maximum value of the geomagnetic triaxial extreme value in the Z-axis direction, and Zmin represents the minimum value of the geomagnetic triaxial extreme value in the Z-axis direction;
Kx, Ky and Kz represent the magnetic field correction factors in the X-axis direction, Y-axis direction and Y-axis direction respectively.
