APSCO Small Student Satellite (SSS) Project
◼ The largest basic activities of APSCO, It was kick-offed in December, 2016.
◼ Launching service will be provided by CNSA .
◼ Member States : Bangladesh, China, Mongolia, Iran, Pakistan, Peru, Thailand and Turkey.
◼ Beihang University was identified as the Leading University.
![Page 5: United Nations / Brazil Symposium on Basic Space ...](https://reader034.fdocuments.us/reader034/viewer/2022042702/6265d2c3c8404731dc4bc8e8/html5/thumbnails/5.jpg)
APSCO SSS Project aims to train students and faculties from
Member States (MS) for satellite engineering through hands-on
practical training until the flight model is made.
◼ Develop their own space education system;
◼ Build their own capability to develop small satellites;
◼ Build their own payload/subsystem integrated on the satellite(s);
◼ Build their own capability to operate satellites and/or process
image/data.

Problems
M.S. universities have established UV or S-band ground
station independantly.
Satellite TT&C coverage and communication time is
limited.
Existing G.S. facilities do not have the operation and
application service efficiency
