The use of the 8 025-8 400 MHz band by Earth exploration-satellite service (EESS) satellites operated by various entities for data downlink operations is increasing and could result in harmful interference between these operators. Potential difficulties in sharing the heavily occupied 8 GHz spectrum may be avoided, if EESS satellite designers carefully select which of the mitigation methods are appropriate for the satellite’s intended operations. In addition to improving the sharing conditions for EESS satellites, many of the mitigation methods can also be beneficial in reducing or eliminating potential coordination with the extremely sensitive space research service (deep space) operating in the adjacent 8 400-8 450 MHz band. This Recommendation provides guidance in the form of a list of possible mitigation methods, shown in recommends, for consideration to reduce the potential for interference by and to EESS satellites given the growing interest in the use of the 8 025-8 400 MHz band by the EESS.
