Abstract
In the control process of trajectory correction projectile, a real-time accurate measurement of projectile roll angle information is required. Geomagnetic and GPS measurement principle is applied for the establishment of the projectile measured roll angle combinations mathematical calculation model, the designing of MR and GPS measuring circuits, and derivation of the singular points of the system and error resolution type. Numerical simulation methods are applied to verify the location of singular points of the combination of measurements and the linear spline combination of interpolation method of compensation the position of the magnetic vector error and the ellipsoid fitting calibration algorithm compensate for magnetic measurement error. The geomagnetic error has less effects on the combination of measured roll angle error, while the pitch angle and yaw angle error has greater impact on the roll angle error. Remove the singular point area, projectile roll angle error is less than 2°when measured by the combination of MR / GPS
