Plum produced two research reports on satellite filing and associated regulatory processes to support a client on the development of its strategy for next-generation wireless communications. The first report examined the regulations and processes for securing access to spectrum and orbital positions for satellite services, including case studies on Starlink (SpaceX) and OneWeb. The second report considered the filing guidelines and charges for selected national administrations and assessed the possible approaches to secure access to spectrum and orbital slots for advanced satellite constellations including Low Earth Orbit (LEO) satellites.
