早期的卫星可以不用惯性器件,其姿态控制和轨道确定采用自旋稳定、喷气技术以及简单的光学测量方法即可实现,但其精度、寿命以及功能往往会受到很大限制。随着航天技术的发展,卫星以及其它航天器在军事、经济诸方面的应用价值日益显著,航天飞行器向着高精度、长寿命和多功能方向发展,这些现代化航天器几乎都离不开惯性技术。无论是为航天器提供主动而精确的姿态测量信息;或者是为其提供连续而长期的执行方法,惯性器件都显示出很大优越性。因
Earlier satellites could eliminate the need for inertial devices, and their attitude control and orbit determination were achieved using spin-stabilization, jet technology, and simple optical measurements, but their accuracy, longevity, and functionality were often severely limited. With the development of aerospace technology, the application value of satellites and other spacecraft in military and economic fields has become increasingly prominent. The high-precision, long-life and multi-purpose spacecraft development has led to the development of spacecraft. Almost all these modern spacecraft can not do without inertial technology. Whether it is providing proactive and accurate attitude measurement information for spacecraft, or providing continuous and long-term methods of implementation, inertial devices have shown great advantages. because
