The increase in space debris has been a major concern for humans. To avoid the risk of collisions in Earth orbit, which can be quite catastrophic for satellites, ways to alleviate this problem have been considered, such as the intensive study of solutions and the development of processing algorithms for object observation. . From the previously presented problem, this dissertation arises, which aims to discuss a possible approach to the issue of detecting objects in GEO surveys, in the context of the pipeline that is being developed. This pipeline is written in the Python language and uses optical sensors that are made up of a system with two telescopes implemented in July 2022 at the Pampilhosa da Serra Space Observatory (PASO). A historical context of space debris is presented, as well as some important technologies and tools in the development of this project. Also, an architecture is presented, that is, the development and implementation of the pipeline. Furthermore, the results obtained are presented and discussed. This work was carried out at the facilities of the Instituto de Telecomunicações – Polo de Aveiro, using images that were obtained at the Pico dos Dias Observatory, located in the State of Minas Gerais, which belongs to the National Astrophysics Laboratory in Brazil. Images provided by the Ministry of Defense, captured by the Deployable telescope, located at PASO, were also used.
