Abstract： According to the overseas communication support needs of Chinese enterprises in overseas， applies VSAT satellite communication technology to cross-border data transmission system， which can support business functions such as fax， voice， video and data transmission. The system adopts the star network architecture， selects the Ku band of Zhongxing 12 satellite， fully considers the indicators such as technical maturity and portability， and analyzes and calculates the satellite link of the system station configuration， so as to ensure the smooth cross-border communication of Chinese enterprises in overseas.

Key words： VSAT; satellite communication; Ku band; cross border data transmission
