摘要
此文阐述了利用DGPS接收机定位精度高的特点 ,按照测定船速的基本原理 ,提出在非测速场测定船速和计程仪改正率的方法 ,并简单叙述了用此方法测定船速的原理、优点、注意事项及误差因素。
Based on the basic theory of determining ships speed and the characteristics of DGPS receiver ,this paper putsforward an approach of determining ships speed and logs corrective rate; Moreover ,it also points out the theory,strongpoint ,notice_deserving points and errors of the approach.
