摘要
Abstract
How to quickly solve the attitude angle and the layout of GPS receiver to improve the measuring accuracy is a hotspot of current research while receiver layout and attitude measurement is conducted by means of carrier phase GPS on ship. The direct method is used in this paper to calculate the ship attitude angle and further study the relationship between the GPS re⁃ceiver layout and attitude measuring accuracy of ship through analysis of baseline length. The basic concept of ship pose mea⁃surement and the relationship between the coordinate systems are introduced. The model to measure the course angle was de⁃duced with the direct method and the influence of baseline length on the measuring accuracy was derived. A conclusion that the longer the baseline length is,the angle measuring accuracy is higher is obtained. The conclusion was verified by simulation test. This conclusion provides the reference basis for erection of the GPS receiver and improvement of angle measuring accuracy.关键词
