11、population has noaccess to the Internet, and the information deficiencyhamperslocal development.It will be Chinas first broadband Internet accesssystem with small satellites hovering in low orbit, whichwill also help meet the needs of commercial space development.The project, named Hongyun, plans to
12、 send the firstsatellite by 2019, and launch four more by 2020. By theend of 2025, CASIC plans to have all of the 156 satellites in operation.The Hongyun Proiect, which focuses on communication,remote sensing and navigation, can offer communicationand Internet services for China and less-developed 3
13、countries with reduced latency. Meanwhile, the projectcan 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,
14、 000 kilometers abovethe 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 1, 000 kilometers above the Earth, and thus could improve the Internet access. However, the
15、low orbit satellites may face challenges in power supply, as they need more energyto reduce the influence of air-resistance compared to highorbit satellites. Experiments are needed to determinewhether solar energy alone is enough.1、According to the passage, _.A156satellites will be launched by the Hongyun Pr
