It will be Chinas first broadband Internet access system with small satellites hovering in low orbit, which will also help meet the needs of commercial space development. The project, named Hongyun, plans to send the first satellite by 2018, and launch four more by 2020. By the end of 2025, CASIC plans to have all of the 156 satellites in operation. The Hongyun Project, which focuses on communication, remote sensing and navigation, can offer communication and Internet services for China and less－developed countries with reduced latency. Meanwhile, the project can also benefit emergency communication, sensor data collection and remote control of unmanned equipment. Currently, international maritime satellites are widely used in communications in mountainous areas and airplanes, but those satellites, 36,000 kilometers above the earth, have time and signal delay as well as high cost for providing services. The small satellites sent by the Hongyun Project will hover in low orbits only hundreds of kilometers to 1000 kilometers above the earth, and thus could improve the Internet access. However, the low orbit satellites may face challenges in power supply, as they need more energy to reduce the influence of air－resistance compared to high orbit satellites. Experiments are needed to determine whether solar energy alone is enough. 【语篇解读】　中国将在2025年前发送156颗卫星，确保世界任何角落都能连上宽带。 词汇小得　①less－developed adj.不发达的；②meet the needs of满足……的需要 1．According to the passage, ________.
