中国这次的卫星了不得，实践十三号卫星创造了我国通信卫星多个“首次”：

Ÿ     　　首次在高轨卫星工程化应用自主研制的电推进系统，完成南北位保任务，大幅提高有效载荷装载比和卫星在轨寿命; 一般卫星在轨10年到20年，用电推进可以延长寿命.

Ÿ     　　首次在我国卫星上应用Ka频段多波束宽带通信载荷，通信总容量达20Gbps，超过我国已研制发射的通信卫星容量总和; 天呢，这么宽的频带呀, 一般我们看电影一部电影大概有一G. 也就是说每秒可以传20部电影. ka是超高频的，在美国这边是属于军用的. 信号收发技术，天线信号处理，要求非常高.

Ÿ     　　首次开展我国高轨卫星与地面的双向激光通信技术试验，速率最高达到2.4Gbps; 激光啊, 以前还是实验室的技术，现在已经应用阶段了！美国这边国防部，尽想着用激光杀人了！像得了狂犬病到处咬人的，拚命烧钱的战争疯子！

Ÿ     首次在我国高轨长寿命通信卫星上百分之百工程化应用国产化产品，改变了相关产品长期依赖进口的局面。超棒啊！以后中国的高科技产品，走遍世界都可以通讯了. 亲爱的主席，88，你们真棒！love you! 

This time, China ’s satellites are so amazing that ShiJian 13th satellite has created many “firsts” of China ’s communications satellites:

Ÿ  For the first time, the self-developed electric propulsion system was applied to the engineering of high-orbit satellites for the first time to complete the north-south protection mission, which greatly improved the payload loading ratio and satellite on-orbit life. Generally, satellites in orbit for 10 to 20 years can use electric propulsion to extend their life.

Ÿ  For the first time, a Ka-band multi-beam broadband communication load was applied to a satellite in our country, with a total communication capacity of 20 Gbps, which exceeds the total capacity of communication satellites that have been developed and launched in China; God, such a wide frequency band, generally we watch a movie. In other words, 20 movies can be transmitted per second. Ka is ultra-high frequency, which belongs to the military in the United States. Signal transmission and reception technology, antenna signal processing, are very demanding.

Ÿ  The first two-way laser communication technology test between China's high-orbit satellite and the ground was carried out, with a maximum rate of 2.4Gbps; laser, the technology of the laboratory was previously used, and it is now in the application stage! The US Department of Defense is thinking of killing people with lasers! Like a war lunatic who has been bitten by rabies and desperately burns money!

Ÿ  The 100% engineering application of domestic products on China ’s high-orbit long-life communication satellites for the first time has changed the situation of long-term dependence on imports for related products. Awesome! In the future, China's high-tech products will be able to communicate all over the world. Dear Chairman, 88, you are awesome! love you!
