Characteristics

The picosatellite was 13 cm long and has a mass of 570 grams. It had five plaques in its structure. Solar arrays in the cylinder were responsible for powering the components of Tancredo-1. 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
