不同于今年3月底远征一号上面级首飞时发射一颗卫星,这一次它承担了两颗卫星的发射工作,任务更为艰巨。为了让北斗双星此次太空之旅更为舒适安全,研制团队对上面级进行了多项优化设计,最终实现了北斗双星平稳分离、准确入轨。

Different from launching a satellite when the expedition first flew to the top of this March by the end of March this year, it undertook the launching of two satellites and the task was even more arduous. In order to make the space shuttle Double Beidou more comfortable and safe, the research team conducted a number of top-level optimization design, and ultimately achieve a smooth separation Beidou Double Star, accurate orbit.
