Research on the design of swing pilot platform for aerial photographic UAV

This thesis first analyses the causes for producing swing angle, and then proposes to reduce this angle by using swing pilot platform. The mechanical structure of the platform is introduced, and a new Magnetic Heading Measurement System based on the magnetoresistive sensor and the MEMS accelerometer is designed. According to the features of main components, the error compensation algorithm is used to make sure the accuracy of direction angle. The test results indicate that the swing pilot platform can keep the direction angle stable even under crosswinds condition. The accuracy of aerial photographic swing angle is within three degrees.
