一九八四年四月八日,我国成功地发射了一颗同步通信卫星。目前,卫星运行良好,工作性能稳定、可靠。它标志着我国航天技术发展到了新的阶段,开创了我国长寿命、高可靠应用卫星的新局面。 通信卫星是由十个分系统组成,控制系统是卫星的关键分系统之一。 由于国产电子元器件的固有可靠性水平较低,使得控制系统的质量可靠性又存在一大难题,长期难以解决。控制系统每套产品采用了1887支(块)电子元器件,其中半导
On April 8, 1984, China successfully launched a synchronous communications satellite. At present, the satellites are operating well and their performance is stable and reliable. It marks the development of China’s aerospace technology to a new stage and has created a new situation for long-life, high-reliability application satellites in China. The communication satellite is composed of ten subsystems. The control system is one of the key subsystems of the satellite. Due to the inherent low level of reliability of domestic electronic components, the quality and reliability of the control system has a major problem, which is difficult to solve for a long time. 1887 (block) electronic components were used in each control system product, of which semi-conductors
