Abstract: 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 4CPFSK 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.
