摘要
随着传输型测绘卫星有效载荷种类的增多和分辨率的不断提高，卫星获取的信息量与卫星系统数据传输能力之间的矛盾越来越严重，同时也牵引着卫星数据传输技术的进一步发展。本文立足于未来传输型测绘卫星发展的需求，从频段的选择、调制与解调、差错控制、高增益天线等几个方面探讨和分析了测绘卫星数据传输技术的发展趋势。
The higher capability of data transmission for mapping satellite is required, with the development of multi-sensor and high resolution. Based on the requirements of future mapping satellite, this paper discusses and analyses the development trends of the data transmission technique for mapping satellite in aspects of frequency band selection, modulation and demodulation, error control and high -gain antenna.
