Abstract

The invention discloses a moving carrier signal receiving system, comprising an antenna (10), a mounting base (2), an absorber (3), a cross rolling axis frame (13), a pitch axis frame (9), an azimuth axis frame (17), three sets of direct current brushless torque motor reduction gears, three piezoelectric gyroscopes, three photoelectric encoders, a sensor, a position and posture measuring system and the like. According to the system, a three-axis structure including the pitch axis, the cross rolling axis and the azimuth axis is adopted, a tracking mode of stepping tracking is adopted, and the embedded system development technology, the driving and control integrated technology and the multimoding intelligent control algorithm are utilized, so that the high stability and tracking feature are achieved. The disturbance of the moving carrier to a satellite receiving antenna is isolated, the stable orientation of the satellite antenna in the moving process is maintained, so that the requirement of receiving satellite signals in the wild or a long journey is met, and the moving carrier signal receiving system is particularly applicable to vehicle-mounted systems and shipborne systems with complex work environments.

Description

technical field [0001] The invention belongs to the technical field of aerial remote sensing, and in particular relates to a motion carrier signal receiving system. Background technique [0002] With the development of science and technology and the needs of some work, satellite antennas are more and more used in various moving vehicles and ships, etc., but satellite antennas often cannot receive signals well due to the disturbance of moving carriers. A stable satellite tracking system is needed. Most foreign mobile satellite tracking systems use three-axis stabilization systems and high-cost and high-precision fiber optic gyro sensors. The technology is relatively mature and the performance is stable, but the price is expensive and the core technology is blocked. At the same time, the field of satellite communications is related to national public security and information security, and it is not appropriate to promote and use foreign products in large quantities in our cou...
