| Palavras-Chave | ENGENHARIA E TECNOLOGIA ESPACIAL Brazilian satellite SCDI Complete Brazilian Space Mission (MECB) spin-axis attitude monitoring |
| Resumo | The first Brazilian satellite SCDI, designed and manufactured by the Instituto Nacional de Pesquisas Espaciais - INPE under the Complete Brazilian Space Mission (MECB) project, was launched on February 09, 1993 at 14:42:20 UTC by a Pegasus rocket of Orbital Sciences Corporation of USA. It is a spin-stabilized satellite and its thermal constraints prohibit the orientation of the spin-axis with respect to Sun's direction to rise above 90 degrees. Due to this condition, some type of spin-axis attitude monitoring was necessary during the useful lifetime of the satellite. Although various types of algorithms were developed for this purpose, unexpectedly, a software, which was developed during the satellite's mission analysis phase mainly in order to furnish the miss ion analysts with a fast, clear and integrated visualization of the preliminary attitude determination results and related aspects, was found useful for this purpose. For each orbit during a specified period, this software prepares and draws on a computer terminal, or optionally on a plotter, in inertial celestial sphere containing: the Sun's position; the Earth's shadow; the geomagnetic field vector trajectory; the satellite trajectory during its pass over a given ground station; and the attitude of the satellite spin-axis enveloped by its predicted uncertainty ellipse. A rational analysis of this map helps a mission analyst to select an optimum sub-set of satellite passes in order to achieve the best possible precision in the attitude determination process. However, besides fulfilling this main objective, after the SCD1 launch. the attitude determination software was found to be useful for various other purposes such as: the study of magnetometer bias fluctuations, observed from one pass of the satellite to other; an easy-monitoring of the spin-axis attitude etc. This software also helped the mission analysts to take some important decisions in improving the main attitude determination software. This paper narrates everything about the attitude follow-up software, starting from the initial idea based on which the software was developed till the developments along time and its final function. Being a debut of the attitude team of the flight mechanics group of INPE, the experience with SCDI related to attitude determination process gave challenging problems as well as pleasant surprises, some of which are from the attitude follow-up software. The main idea of this work is to share our first-hand experience with the first Brazilian satellite SCD I in the process of its attitude follow-up. |
