To solve attitude measurement problem of the gun-launched cruise projectile under high over load
a precision measurement method was proposed
based on geomagnetic field.The measuring principle and the mathematical model were derived in detail.The attitude measurement error was simulated and analyzed.The results show that the measurement error is less than 0.5° during climbing and expansion course.The hardware construction was also provided.This measurement technology has the advantages of less element
simple structure and stable operation.It can be used to other vehicle attitude measurement systems under high overload.
