Usually, a flying carrier can be controlled well, its three attitude angles must be accurately measured. However, in some cases, traditional inertial measurement equipment is difficult to measure the three attitude angles of flying carrier when rotating at a high-speed, especially in the rolling direction. In order to solve the rolling measurement problem in a high-speed rotating carrier. Three methods are proposed here. Two of them only use magnetic sensors to measure geomagnetic filed. The third method use magnetic sensors combining with a MEMS gyroscope (gyro). It can not only avoid increased angle error due to gyros measurement but also efficiently resist magnetic field interference. Finally, in order to verify the three methods, the experiment is carried out on a real system. The three methods are compared through measurement error analysis, and the adaptation of environment is summarized. Results show that methods by measuring geomagnetic filed can accurately calculate the roll angle of a high-speed rotating carrier.
