| Headline Details: A 3U Cubesat intended to be deployed from the ISS in early 2015-The main mission is to provide capacity building experience to students, providing a complete hands-on experience, from mission design, systems engineering to on orbit operation. The space station will give the possibility to students to become familiar with operations such as satellite tracking, telemetry Amateur Satellite Frequency Coordination Request — Page Rev. 27 12 MAR 2012 3 reception and part of the satellite command and operation. These tasks will help to consolidate young (less than 5 years old) federal aerospace courses in Brazil. A radio amateur experiment of messages storage and forward will also be conducted in the spacecraft. Radio amateurs will be able to send and store messages in the onboard computer, that can be later retrieved in different parts of the world. For safety energy levels maintenance, a fix number of access on this experiments each will be fixed. The secondary goal is (a proof of concept) to evaluate the use of nanosatellites (CubeSats) for data collection. For this secondary mission goal, the Nanosatellite will embed a Humsat transponder (www.humsat.org). The Humsat transponder will collect data from sensors (mainly environmental sensors such as wind, humidity, water levels, etc), store it on-board and transmit it to university ground stations. All the transmission and reception of the experiment are open and without any pecuniary interest. The collected data will also be available through Internet for the any users that might want to explore this environmental database. Although the satellite will use radio amateur band to perform a proof of concept involving nanosatellites and data collection systems, it should be noted that this band is used only for the proof of concept purpose, given it’s a university project focused on education and training. It should be clear that this space station will not encourage the use of radio amateur band for data collection systems. If any solutions come to be adopted for data collection in Brazil using nanosatellites, these solutions will handle the license and coordination of their frequencies as recommended by the Brazilian National Telecommunications Agency and the International Telecommunications Union. The experiments with the space station can be conducted by students in several universities of Brazil, as well as in Federal Institutes of Education and in the National Amateur Radio Society. Universities and the radio amateur community are invited to develop their own sensors compatible with Humsat (documentation of interfaces is available).Proposing 1k2 VHF and 9k6 UHF downlinks. The telemetry decoding information can still be subject to adaptations. Among other places, the information will be made public in the website (http://www.aerospace.unb.br) and Humsat project website (http://www.humsat.org/)** Downlink frequencies of 145.980 MHz and 437.365 MHz have been coordinated** | ||||
