| Abstract: |
| This paper analyzes and summarizes the development and achievements of LM-3A series from the aspects of vehicle system and its guidance & navigation control. After the LM-3 launch vehicle established the high orbit launch capacity of China, the LM-3A series launch vehicles developed from basic capacity to high adaptability and obtained the high orbit launch capacity for large-scale satellite .Technical breakthroughs are made on launch capacity for orbits from single orbit plane to multiple orbit planes, from transfer orbit to satellite operation orbit, from earth orbit to lunar transfer orbit, and on mission targets from the ones for technology testing to the ones for high reliability engineering applications. These enhanced the launch capacity of China to the level of all earth orbit injection and interplanetary orbit injection. The experiences of China national projects and international commercial launch service show that this series of launch vehicles has entered the forefront of the global high orbit launch vehicles and laid the foundation for further development. |
