讨论了在传统航天测量船测量模式与新测量船使用的分布式测量模式之间,船位数据使用方式的差别。指出了在分布式测量模式下,研究一种使用已知点位数据等效计算其他点位数据的方法是必要的。把测量船船位数据替代问题抽象为具有一般性的位置替代问题。通过建立中间坐标系的方法,将位置数据替代过程分割成3个步骤,并且给出了每个步骤的数学表达式。最后通过测量船海上校飞试验数据对该位置数据替代方法进行了检验,结果表明在包含测量误差的同时,使用本方法计算得到位置数据,一致性和精度均满足任务要求。 Discusses the differences in the way ship data are used between the traditional spacecraft measurement mode and the distributed measurement mode used by the new survey vessel. It is pointed out that in the distributed measurement mode, it is necessary to study a method of equivalently calculating other point data by using the known point data. Abstraction of the survey ship position data replacement problem as having a general position replacement problem. By establishing the middle coordinate system, the position data substitution process is divided into three steps, and the mathematical expression of each step is given. Finally, the test data of offshore school-based test ship was used to test the alternative method of location data. The results show that the method can calculate the position data with the measurement error and the consistency and precision meet the mission requirements.
