摘　　要：曼厅大沙坝浅滩位于景洪下游30 km的大橄榄坝,是一个散流、游荡型浅滩,是澜沧江航运的一个卡口河段,若采用传统航标,其使用和维护效率很低。针对澜沧江流域地理环境险恶,常规通信方式无法完成数据传输的特点,介绍了一种通过卫星通信方式和逆向差分方法实现在该河段的智能航标的研究及应用。Manting Dashaba is a shoal at Daganlanba, 30kms downstream to Jinghong. It is hard to sail in Lancang River, which causes inefficiency by traditional operation and maintenance. The data can not be transmitted by traditional communication way in that Lancang Valley is mountainous. Therefore, this paper introduced a new communicaion way, which is by satellite communication and backward difference to make intelligent navigation mark put into use in the river.

关 键 词：澜沧江 智能航标 卫星通信 逆向差分
