| 摘 要： | 根据海道测量精密测量的需求,对姿态与定位数据融合的同步方法进行了研究。通过GPS大地高数据和升沉数据,建立了一种基于相关逼近原理的定位与姿态数据同步模型。该模型能够确定定位与姿态数据的相对延时,实现两类数据在同一时间基准下的同步。实例计算表明,定位与姿态数据的相对延迟时间已成为两类数据融合应用中必须考虑的因素。由同步模型解算后,GPS大地高数据与总升沉数据体现了更好的一致性,由此也验证了模型的有效性。

| Abstract: | In terms of the requirements on the high-precision positioning for hydrographic survey,the method of the synchronization between the positioning and attitude data is studied.With the geodetic height data and the heave data measured,the synchronization model,is presented in the paper,based on the principle of the correlative approximation.The relative delay determination and the synchronization between the positioning and attitude data can be implemented.Numerical results indicate that the relative delay bet... |
