摘要

频率选择是开展手机直连卫星发星工作的首要问题，也是发星的技术基础。为此，对手机直连卫星通信频率选择进行分析研究，先从政策、国内外协调层面分析国际移动通信（International Mobile Telecommunications，IMT）频率用于手机直连卫星的可行性，再从技术层面研究IMT频率的星间互调及星地干扰影响。通过完善用频方案，为开展不同轨位手机直连卫星的应用提供高可靠性、高可用度的选频思路，这对加快手机直连卫星系统建设具有重要意义。

Abstract

Frequency selection is the primary consideration and technical foundation for launching satellites for direct-to-ell satellite communication. To this end

the frequency selection for such communication systems was analyzed and studied. The feasibility of using International Mobile Telecommunications (IMT) frequencies for direct-to-cell satellite communication was analyzed from the perspectives of policy and international coordination. It then investigated the technical impacts

specifically inter-satellite intermodulation and satellite-to-ground interference

within the IMT frequency bands. By refining the frequency utilization plan

a highly reliable and available frequency selection approach was provided for various orbital applications of direct-to-cell satellite. This work is of great significance for accelerating the development of direct to cell-satellite systems.
