Abstract: This report assesses the expansion of the Earth Exploration-Satellite Service in the 8025–8400 MHz frequency range. The report identifies allocations, standards, regulations and current and planned spectrum usage applicable to this range for Government, non-Government, and international operations. In addition, various potential interference scenarios among the EESS systems and the various other services (operating in this range) are identified.
U.S. Government and non-Government entities will launch Earth exploration-satellite service (EESS) systems in the 8025–8400 MHz frequency range based on the policy directive on remote sensing space capabilities signed by President Clinton (attached in Appendix A; this policy is dictated by public law, Land Remote Sensing Policy Act of 1992). With the introduction of new and increased use of the EESS systems in that range, the potential for harmful interference exists among the various users of these and adjacent bands. NASA, among other Government agencies, is concerned by Earth exploration-satellite service use in the 8025–8400 MHz frequency range in today's as well as future markets. One method of monitoring the use of the 8025–8400 MHZ frequency range by Earth exploration-satellite services is the Space Frequency Coordination Group (SFCG), (September 1994) of which NASA and NOAA are members.
