摘要
针对浮船坞标校的特点,提出了利用动态GPS进行标校的新方法。该方法可连续获取被试设备位置信息,从中挑取与被试设备自身测量同历元的GPS数据进行方位标数据解算,然后与设备测得的数据进行比对,可有效提高浮船坞标校精度。从而解决了动态标校的实时性、一致性和准确性问题,在实际应用中取得较好效果。
In view of the characteristics of floating dock calibration,a state-of-the-art calibration method proposed by utilizing dynamic GPS.The method made it possible to continually obtain the positional information of the calibrated apparatus,among which seek out those share the identical epoch GPS data with the calibrated apparatus itself to calculate the azimuth mark data,and then to contrast them with data from the calibration unit.It can effectively improve accuracy of floating dock calibration and tackle the immediacy,compatibility and accuracy of dynamic calibration,thus achieving positive results in practical application.
