Abstract

The invention discloses a satellite communication in motion attitude detection device and method. The device comprises satellite communication in motion, a microprocessor, an attitude detection moduleand a complementary filter, the attitude detection module comprises an X-axis attitude detection module, a Y-axis attitude detection module and a Z-axis attitude detection module; the method comprises the following steps of three-axis coordinate system building and attitude detection module layout, real-time information collection and uploading, satellite communication in motion three-axis weighted fusion angular velocity value obtaining, satellite communication in motion attitude angle obtaining and satellite communication in motion attitude angle correction. Accordingly, design is reasonable, by means of fusion of multiple micromechanical gyroscope homologous sensors and fusion of micromechanical gyroscope and accelerometer heterogenous sensors, the satellite communication in motion attitude can be accurately obtained, the cost is low, the reliability is high, the precision is high, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of micro-inertial attitude attitude, and in particular relates to a satellite-in-motion communication attitude detection device and method. Background technique [0002] Satellite communication in motion is an important branch of satellite communication. The essence is to move satellite communication in motion to a moving carrier, use fixed satellite communication resources, and establish and maintain satellite links with target satellites in a moving or stationary state. satellite communication system. The special feature of satellite communication equipment is that the antenna has high gain and narrow beam, and the antenna is placed on a carrier that moves irregularly and continuously. To ensure the quality of communication, the antenna beam must always be aligned with the satellite. The International Telecommunication Union stipulates that the pointing error of the Ku-band vehicle-mounted satellite earth...
