Dynamic geographical spectrum sharing
View Patent ↗Methods, apparatuses, computer-readable mediums for storing software, and systems for dynamic geographical spectrum sharing (DGSS) by Earth exploration satellite services (EESS) are described herein. Using DGSS mechanisms described herein, electromagnetic spectrum may be shared by sensors onboard Earth exploration satellites and wireless networks, such as 5G networks. The DGSS mechanisms may include mechanisms for determining an instantaneous field of view (IFOV) and mechanisms for modifying transmission characteristics while network antennas and power radiated by such antennas are within a window encompassing the IFOV. For example, when the IFOV of a satellite sensor for measuring atmospheric water includes a 5G antenna, the power of the 5G antenna may be reduced, the 5G antenna may be prevented from utilizing a segment of the electromagnetic spectrum, etc. The DGSS mechanisms may also determine actual out of band emissions for a specific pixel associated with the IFOV and improve pixel location determinations.
