Tancredo-1 is a Brazilian picosatellite, it is a TubeSat which was developed by the students from the school Tancredo Almeida Neves, in Ubatuba (SP), with support for the picosat platform made by Instituto Nacional de Pesquisas Espaciais (INPE), adapting and integration to launch provided by TuPOD from Italian company GAUSS Srl and by Agência Espacial Brasileira (AEB).
The idea was proposed by the math teacher Cândido Oswaldo de Moura, inspired in a reportage about the "TubeSats", kits to build “personal satellites” developed by the company Interorbital Systems, in United States. To start the project, the teacher made contact with the Instituto Nacional de Pesquisas Espaciais (INPE), where, later, he was followed by another's teachers to receive training and be able to help the students. The material to construct the satellite was paid for by salesclerk of Ubatuba and the launch was possible with help of AEB. The satellite receive the name of “Tancredo-1”, in homenage to school.
The picosatellite is 13 centimeters long and has a mass of 570 grams. The equipment has five plaques in its structure. Solar arrays in the cylinder are responsible for powering the components of Tancredo-1. A space exists inside the satellite what can be used for small scientific experiments in space, in the case of Tancredo-1, two payloads are used: one voice recorder for radio-amateurs, educational payload and one simplified Langmuir probe to study the formation of plasma bubbles in ionosphere made by National Institute for Space Research. The platform tubesat passed by a total re-engineering from the work to Mestrado em Engenharia de Sistemas Espaciais Eng. Auro Tikami from INPE with orientation of Walter Abrahão dos Santos – INPE.
