Space situation monitoring equipment, ground facilities

Abstract

The objective is to provide flight safety measures that avoid collisions between artificial satellites and space objects under favorable conditions. [Solution] The observation satellite 200 changes its flight speed after it has begun orbiting one side of the Earth 101 (either the near side or the far side) through orbit control by ground equipment. As a result, the orbital altitude of the observation satellite 200 changes from the altitude of geostationary orbit 103. Furthermore, the observation satellite 200 changes its flight speed again before it begins orbiting the other side of the Earth 101 (either the near side or the far side) through orbit control by ground equipment. As a result, the orbital altitude of the observation satellite 200 returns to the altitude of geostationary orbit 103. Through orbital control, the space situational awareness system equipped with the observation device 200 provides a flight safety measure to avoid collisions between artificial satellites flying near geostationary orbit and space objects.
