The remote sensing of Earth from a geostationary orbit can be achieved by deploying four independent spacecraft organized in a tetrahedral configuration.This innovative arrangement enables the substitution of a large optical telescope system.This paper delves into the challenges associated with studying the motion and maintenance of a tetrahedral formation of satellites in a geostationary orbit for Earth observation.To maintain the tetrahedral or regular pyramid configuration in an undisturbed reference orbit, algorithms based on the root locus method and feedback methods were developed.Through the course of this research, it was determined that these control methods for managing satellite motion within a formation could also be effectively applied to regulate the relative positions of satellites in a Fizeau interferometer configuration within geostationary orbits, particularly when utilizing modern electric propulsion systems.
