Chinese aerospace giant to launch 156 mini-satellitesBeijing, March 31 (AZINS) A Chinese aerospace giant on Friday announced plans for a network of 156 mini-satellites to facilitate global broadband coverage.

This is the first low orbiting networked satellite project, which will orbit 1,000 km above the ground, developed by China amid its wider push for commercial space development, the China Aerospace Science and Industry Corporation (CASIC) said.

"The network is a general satellite platform," said Bei Chao, a CASIC engineer, who added that add-ons and upgrades were being explored next.

Small satellites are easy to mass produce and upgrade at low cost, Xinhua news agency reported.

Low orbit helps avoid signal delay -- and satellite communication services with frequencies from 26.5 to 40 hertz will improve internet access.

The project plans to send up the first satellite before 2018, and launch four more by 2020 to form a constellation.

By the end of the 14th Five-Year Plan (2021-2025), all 156 satellites will be in operation.

CASIC launched an experimental satellite "TK-1" in early March, featuring high-carrying efficiency and adaptability.
