On May 31st, the Centre organized the 6th technical visit to the Twenty First Century Aerospace Technology Co., Ltd. (21AT). Participants from 2017 MASTA&DOCSTA Program attended this visit and gave high praise to it. Here is one journal article from Mr. MD. REJAUN NABI, a 2017 MASTA participant in RS&GIS from Bangladesh.

The Twenty First Century Aerospace Technology Co., Ltd. (21AT) was founded in June 2001 in Beijing. It was the first independent commercial satellite operator and non-governmental investor in remote sensing satellite system in China. It is also the first private company that vertically integrated EO satellite operator and services businesses. It owns several low cost EO small satellites, including the 1m optical EO small satellite constellation, and the satellite control & image tasking and receiving stations. Now there are more than 600 employees working in this organization in various post. For the past 16+ years, it provided Triple Sat constellation satellite imagery basis services in the world and still going on.

We, participants of 2017 MASTA & DOCSTA program, had the great opportunity to visit this company as a part of our technical visit on May 31st, 2018.
