摘　　要：星载VHF系统是中法天文卫星SVOM (Space Variable Objects Monitor)的重要组成部分,为科学目标位置信息及重要数据提供VHF频段的准实时信息下传通道.本文介绍了SVOM卫星星载VHF系统的设计方案,对单机设计、软件设计和调制算法设计等进行了详细描述. SVOM卫星VHF系统是中国首个采用4CPFSK调制方式设计的VHF频段星载数据传输系统.测试和试验表明,星载VHF系统的工程实现满足卫星应用需求,为空间科学卫星重要数据实时传输提供了解决方案.The on-board VHF system is an important part of the SVOM satellite. It provides a quasi-real-time VHF-band information access channel for the location information and the important data of the scientific target which is detected by payloads. In this paper, the design of VHF system on-board SVOM is introduced. The equipment design, software design and modulation algorithm design are described in detail. SVOM VHF system is the first application of 4 CPFSK modulation in VHF band for spaceborne data transmission in China. Test results show that the implementation of the VHF system can meet the application requirements of the satellites and provides a solution for the real-time transmission of important data of space science satellites.
