Headline Details: The Tancredo 1 Tubesat is the first satellite of the Ubatubasat Project, designed in the elementary school “Presidente Tancredo de Almeida Neves” , located in Ubatuba, São Paulo, Brazil. Our goal is to arouse the interest in Science and Technology in our students, aged between ten to fourteen ( the youngest team in the world to build a satellite). Our tasks range from integration, testing, assembly, coding, launching and operating the satellite, aiming students to pursue careers in the science and technology areas, especially in the Space Engineering fields. The project has received since its inception the technological support from INPE, AEB- Brazilian Space Agency and UNESCO. Additionally, it is getting a lot of repercussion in the Brazilian and World media as well as a great support from the scientific community. Tancredo 1 was developed from a commercial kit supplied by the company Interorbital Systems from CA-USA, the original project has been greatly modified and improved by the project team, especially by the engineer Auro Tikami from INPE, as part of his masters dissertation.Tancredo 1 has a on-board voice recorder IC as payload, that will transmit a message chosen by a contest among students from our schools in Ubatuba. The Tancredo 1 TubeSat ground station segment will make the down and up radio data links using a ground stations located at Ubatuba which is provided by the Brazilian Space Agency (AEB). This ground station may receive also other tubesats, cubeSats or even small satellite signals in Low Earth Orbit – LEO which uses radio amateur frequencies. Some of the cubesats are from university initiatives such as: UFSM, ITA and INPE all in Brazil. Finally, the ground station is a compact turnkey setup with full Azimuth and Elevation tracking, designed for LEO applications and ready for the Global Educational Network for Satellite Operations initiative (GENSO).The 92.5mm x 127mm TubeSat is planning a UHF 1k2 AFSK downlink with AX25 being implemented. Expected to be deployed from the iSS in Nov 2014. More info from www.tancredoubatuba.com.br/ubatubasat ** A downlink on 437.200 MHz has been coordinated**
