Development

The idea to develop a satellite was conceived in 2013. On 15 June 2016, Syed Saad Andaleeb, Vice Chancellor at BRAC University, signed a contract with the Kyushu Institute of Technology (Kyutech),

, on behalf of BRAC University. This led to the collaborative building of the first experimental university-made nano-satellite of

, designed, developed and assembled by three Bangladeshi students at the Kyushu Institute of Technology. On 8 February 2017, Andaleeb received ''BRAC Onnesha'' from Kyutech's President Yuji Oie and Mengu Cho, Kyutech's Director of the Laboratory of Spacecraft Environment Interaction Engineering. BRAC University took up an initiative to start space and remote sensing research in collaboration with Kyutech and the Space Research and Remote Sensing Organization (SPARRSO). BRAC University has built a ground station at its Mohakhali campus to analyse data and photographs sent from space for further research purposes. Professor Mengu Cho of Kyutech said, "''BRAC ONNESHA'' was easy to build and affordable and their prime objective was to educate the students so that they could go back to build one completely by themselves, presumably in October 2017". The two-year period spanning the development, construction, launch and operation of the satellites engaged three university students from each of the five participating countries. All five satellites had to be identical to each other in the class of a 1U CubeSat. The satellite cost about US$500,000 to manufacture and launch. They were expected to last 1.1 years.
