It was a TubeSat which was developed by the students from the school Tancredo Almeida Neves, in Ubatuba (state of São Paulo), with support for the picosat platform made by Instituto Nacional de Pesquisas Espaciais (INPE), adapting and integration to launch provided by TuPOD[2] from Italian company GAUSS Srl and by Agência Espacial Brasileira (AEB).

[3][4][5][6] The idea was proposed by math teacher Cândido Oswaldo de Moura and initially developed by Emerson Issao Yaegashi, it was inspired by Super Interessante Magazine in Brazil and in a video called "TubeSats" and kits to build personal satellites developed by the company Interorbital Systems, in the United States.

Some space existed inside the satellite that could be used for small scientific experiments in space, in the case of Tancredo-1, two payloads were used: one voice recorder for radio-amateurs, educational payload and one simplified Langmuir probe to study the formation of plasma bubbles in the ionosphere.

The platform tubesat passed by a total re-engineering from the work to Mestrado em Engenharia de Sistemas Espaciais Eng.

[8] Almost 100 students took part in the project with the job of welding pieces and building electric circuits.
