摘　　要：本文以美国天宝公司的GPS系统为研究对象,以匀速行驶的船只为模型,在有数据传输和无数据传输的影响下,分析了在单波束水下地形测量中GPS延时值的计算,并提出了减小GPS延时误差的方法。同时,对非匀速行驶的船只,GPS延时值的情况也作了探讨。We take theTrimble-R10 GPS system as the research object. The moving boats as the study model. We analyzed the GPS navigation time error in underwater terrain via the use of single beam and proposea method to reduce the error of GPS time delay under the influence of data transmission and no data transmission.At the same time, the GPS time delay value for nonlinear moving ships is also discussed.

关 键 词：GPS 延时误差 地形测量
