The Project aims to develop a space mission using a cubesat. This type of satellite was developed in the US as a standard a 1 liter cube with a 1 kg. mass. This standard became known as 1U. Later the 2U, 3U,....12U etc. Standards were created using this 1U the standard module to the assembly of these larger, but still very small and low cost, nanosats. They don´t use space qualified electronic components, but rather COTS type electronic components. Presently, this type of satellite, at its beginning used for university projects, have developed into different applications both in the public as well as in the private sector in operational and scientific missions such as in remote sensing and vehicle localization such as ships and boats and aircrafts. This miniaturization is possible, with gains in efficiency and performance, due to the electronic revolution that has occurred before and already reached the communication and computer sectors, allowing low cost space missions which just a few years ago were launched with significantly much higher costs. The project aims the complete development of a space mission with a 1U cubesat. Since its conception and specification up to the cubesat bus and payloads development, its integration, testing, launching and operation. In Phase 1 of technical feasibility, the mission and the payloads will be defined followed by a technical feasibility analysis of the bus subsystems development (structure, on board computer, communication, power and control) that could be developed by Brazilian small companies, within a cost range competitive with equivalent foreign suppliers already in the market. The company proposing this project will be the prime contractor for the subsystems and will integrate it and with the payload equipment, along with the mission on board and ground softwares, tests, launch contracting and operation. In Phase 1 the Brazilian developed subsystems will be defined and by which other companies, as well as those that will be developed by foreign companies. Integration and tests will be performed at the Integration and Testing Laboratory (LIT) of the National Institute for Space Research (INPE), which regularly provide this type of services to other Brazilian industries. In Phase 1 will also be defined the orbit requirements for the mission (altitude, orbit plan inclination angle etc.) and its nominal life in order to select the launcher. The cubesat will operate in amateur radio frequencies and thus for its operation (telemetry and telecommand) the two existent cubesats ground stations in the cites of Santa Maria and São José dos Campos, used to operate NanosatC-Br1 launched by INPE in 2014, will also be used. Amateur radio ground stations around the world will also be able to track the cubesat. In Phase 2 the engineering model for the satellite will be developed, with its platform subsystems and payload equipments, integrated and tested for vibration, thermal vacuum cycling and electro-magnetic compatibility as well as one launching opportunity and launcher defined. In Phase 3, with funding from other stakeholders, the cubesat will be launched and operated. (AU)
