Study on Error Correction Method for Navigation System of Gliding Extended-range Projectile
摘要
Abstract
To improve the attitude measurement precision of gliding extended-range guided projectile (GERGP), the attitude-angle calculation-method based on single-antenna GPS measurement was analyzed. To realize the full parameters errors correction,a Kalman filter with position,velocity, attitude errors from GPS/INS was designed, and the estimated results were adopted as the INS feedback. The numerical calculation and simulation show that it can reduce the three attitude-angles of the system and quicken the error constringency speed to apply Kalman filter based on GSP attitude-angle measurement to correct INS attitude-angles errors, and the control precision and gliding extended-range effect of GERGP were improved.关键词
