| 摘要: |
| 无线电频率是不可再生的资源，频率共用已成为国际电信联盟的共识，多业务融合发展已成为世界卫星无线电系统发展趋势。S频段中2483.5 MHz ~ 2500 MHz被国际电信联盟划分为卫星多业务共用频率，包括卫星无线电定位报告业务、卫星无线电导航业务、卫星移动通信业务三大业务，可以同时提供卫星导航、航路跟踪、遇险救援、信息中继四大功能。介绍了S频段天基系统发展过程、导航通信频率特性、S频段多功能集成前景，我国北斗未来使用S频段导航的应用成果及社会经济效益预测。 |

| Abstract: |
| Radio frequency is a non-renewable resource, and frequency sharing has become the consensus of the International Telecommunication Union. Multi-service integration has been the development trend of the world radio satellite system. S band 2483.5 MHz ~ 2500 MHz has been allocated into the sharing band of satellite multi-service including radio determinations satellite service, radio navigation satellite service and mobile satellite service by International Telecommunication Union, and is expected to provide four functions: satellite navigation, route tracking, emergency rescue and information relay. The development of S band space based system, the frequency characteristics of navigation communication and the prospect of S band multi-service were introduced, the future application and social and economic benefits of the S band navigation in China were predicted. |
