中國要發156顆低空衛星，全球無死角Wi fi！

China will launch a network of 156 mini-satellites to facilitate global broadband coverage as part of the country's effort to give a wider push for commercial space development.
中國擬發射156顆小衛星，以實現寬帶全球覆蓋，大力推動商業航天事業的發展。

This is the first low orbiting, networked satellite project, which will orbit 1,000 km above the ground, state-owned China Aerospace Science and Industry Corporation (CASIC) said.
中國航天科工集團公司（簡稱“航天科工”）表示，這是首個低軌、組網衛星工程，衛星將在距離地面1000公里的軌道上運行。

"The network is a general satellite platform," said Bei Chao, a CASIC engineer.
貝超是航天科工的一名工程師，他解釋說：“這是一個通用衛星平臺。”

Small satellites are easy to mass produce and upgrade at low cost.
小衛星易於量產，而且更新換代成本低。

Low orbit helps avoid signal delay and satellite communication services with frequencies from 26.5 to 40 hertz improve Internet access.
低軌可以較好地規避信號傳播延時，利用頻率範圍爲26.5到40赫茲的波段佈局衛星通信業務，則能提高網絡接入速率。

The project plans to send the first satellite before 2018, and launch four more by 2020 to form a constellation.
該項工程計劃在2018年之前發射第一顆衛星，在2020年之前再發射4顆衛星，組成一個小“星座”。

By the end of the 14th Five-Year Plan (2021-2025), all 156 satellites will be in operation, state-run Xinhua news agency reported.
據新華社報道，十四五規劃（2021年至2025年）結束前，將實現所有156顆衛星組網運行。
