摘要
本文采用3个二自由度挠性陀螺仪构成陀螺稳定平台,实现中等精度的电控罗经、高精度的方位水平仪和稳定平台等功能。陀螺稳定平台对飞机飞行条件依赖较小,能承受30 g冲击加速度,正常启动时间10 min,水平精度≤0．2°,方位漂移精度≤0．2°/h,方位任意预置并连续显示,其整体技术性能优于LEICA公司PAV30型陀螺稳定平台。在北京地区、华中地区进行了5次不同高度飞行实验,精度满足航空摄影要求。
This paper reports on a hardware and software design of a gyro-stabilized platform system that implements the functions of a middle precision electric-control compass, a high precision azimuth level detector and a stabilized platform. The gyro-stabilized platform is based on three two-degree-of-freedom dynamically tuned gyroscopes, which rarely depends on the flying navigation conditions of the aircraft, The gyro-stabilized platform can endure the acceleration wallop force of 30 g, the normal start time is 10 min, the horizontal accuracy is less than 0.2°, the azimuth drift error is less than 0.2°/h, and the azimuth can be set to any angle and displayed continuously, The whole performance of the gyro-stabilized platform is batter than that of PAV30 gyroscope stabilized platform from LEICA Company, The flight experiments with 5 different flying altitudes were carried out in Beijing and Central China areas; the experiment data show that the resultant accuracy satisfies the requirements of aerial photography.
