Observation of the Terrestrial Radio Environment Using the Low Earth Orbit Satellite Constellation

In recent years, spectrum sharing is one of the technologies to solve the depletion of spectrum resources due to the increasing demands for wireless communications. In spectrum sharing using a database, there is a method to use radio wave environmental data in order to improve the accuracy of interference calculation. When making the radio wave environmental data into statistics, it is necessary to measure the received power intensity at each position. However, this is difficult for a large area. Therefore, in this paper, the concept of a method to measure the received electric field intensity on the ground using a satellite constellation is proposed and examined.
