为了发射人造卫星等,对火箭必须进行精确的制导和控制。在这种场合,作为必须的姿态基准装置,有平台系统和捷联系统两种方式。但是无论哪一种方式都是以变位陀螺为中心结构。在过去虽然有用2自由度陀螺的倾向,而现在从精度和可靠性方面考虑,多采用单自由度积分陀螺。在平台系统中,为了保持安装陀螺的平台相对惯性空间的稳定姿态,用陀螺检测零位,所以陀螺的输入角越小越好。而在捷联系统中,陀螺是固定在火箭的本体上,其输入角为对应火箭本体的运动,必须能感受很宽的转角范围。不过,平台系统结构复杂,为了提高精度需要很高的技术,而且尺寸大,重量重都是不可避免的。与此相反,捷联系统只
In order to launch satellites, the rocket must be accurately guided and controlled. In this case, as a necessary posture reference device, a platform system and a strapdown system are two ways. However, whichever method is based on the displacement gyro as the center structure. In the past, although there is a tendency to use a 2-DOF gyro, and now from the accuracy and reliability considerations, the use of single-degree-of-freedom integrated gyro. In the platform system, in order to maintain a stable attitude of relative inertial space of the platform on which the gyro is installed, the zero position is detected by the gyro, so the smaller the input angle of the gyro is, the better. In the strapdown system, the gyro is fixed on the rocket body, the input angle corresponds to the rocket body movement, must be able to feel a wide range of corners. However, the platform system structure is complex, in order to improve the accuracy requires high technology, and size, weight are inevitable. In contrast, the strapdown system only
