| 摘要: |
| CZ-3A系列运载火箭承担了北斗工程，包括北斗一号、北斗二号和北斗三号的全部发射任务，被称为“北斗专列”。在北斗工程历时26年的研制过程中，CZ-3A系列火箭突破了一系列关键技术，使火箭具备了从地球同步转移轨道(GTO)到倾斜同步转移轨道(IGTO)、中圆转移轨道(MTO)，从一箭一星发射至转移轨道，到一箭双星发射至转移轨道，再到一箭双星直接发射入轨的发射能力，实现了跨越发展。满足了北斗工程的发射任务需求，北斗工程共计44箭、59星，CZ-3A系列火箭发射均获得了圆满成功，成功率达到了100%。 |

| Abstract: |
| The LM-3A series launch vehicles undertook all the launching missions of the Beidou-1, Beidou-2 and Beidou-3. During the development of the Beidou missions, the LM-3A series launch vehicles developed groundbreaking technologies and achieved the spanning development. The ability of launching different payloads to GTO, IGTO and MTO has been processed, from sending one satellites into transfer orbit to sending two satellites into transfer orbit, furthermore to sending two satellites into the orbit directly. The launch requirements of the Beidou mission have been met, with 44 launches and 59 satellites in total. All the launches were successful, with the success rate of 100%. |
