【Abstract】 To apply a certain simple control to the rocket, the real-time detection of rocket rotation angle is needed. A thorough study of the relation between geomagnetic induction voltage and the movement of the rocket is conducted and a new method for detecting rocket rotation angle is put forward based on the recording of the time when induction voltage reaches zero. The blind area of the detection is discussed also in the paper. With its comparatively simple combination, the method tends to meet the requirement of real-time measurement, high reliability, low cost, and high feasibility.更多还原
