Abstract: Frequency resources are one of the strategic resources supporting the development of the aerospace industry and have non-renewable properties. With the development and utilization of the Moon becoming an international hotspot gradually, the demand users for frequency resources in the cislunar space is shifting from a small number of exploratory tasks related to space research to large-scale and serialized deployment tasks such as the construction of space infrastructure, in-situ resource development and utilization, and manned/unmanned lunar landings and stays. However, under the existing international regulatory framework, the frequency resources available for large-scale lunar development and utilization tasks are extremely limited, and the contradiction between supply and demand is becoming increasingly acute. Based on analysis of advance publication information or notification information of frequency resources for cislunar space stations, as well as the planning and on-orbit exploration mission, this paper summarizes current state and development trend of cislunar frequency resources. By simulation on self-developed software, quantitative interference calculation and analysis were performed on typical international tasks. Frequency utilization recommendations for future cislunar satellite missions are proposed, providing advice for frequency design of cislunar mission.
