| 摘要: |
| 新一代航天测量船采用的分布式船姿船位测量体制提高了数据的准确性和可靠性，同时也给数据处理与使用提出了更多的需求，比如姿态数据一致性检验、姿态数据联合使用等。为此，提出了一种新的船姿数据重构方法。首先，对集中式与分布式测量机制进行了对比，分析了采用传统数据处理方法解决新需求会产生困难的原因，并指出姿态重构数据的取得将成为解决这些问题的关键；然后，分两个过程对分布式船体姿态测量数据的重构方法进行了推演，并说明了如何使用重构数据去解决新需求；最后，在重构数据本身精度和重构数据对飞行器目标定位精度影响两个方面对该重构方法进行了检验，结果表明使用该方法得到姿态数据满足任务精度指标要求。 |

| Abstract: |
| The application of distributed ship attitude and position measurement system in the new space tracking ship makes data more reliable and accurate,but requires more for the data processing and application,such as attitude data consistency checking,attitude data combined utilization. To solve above problems,a reconstruction method of ship attitude data is proposed.Firstly,the distributed measurement system is compared with the centralized measurement system. The reason that it′s difficult to meet new demands with traditional data processing method is analyzed. The analysis shows that reconstructing attitude data is the key to these problems. Secondly,the ship attitude data reconstruction method is derived by two processes,and how to use the reconstructed data is explained.Finally,the data reconstruction method is tested from the accuracy of the reconstructed attitude data itself and the impact on the accuracy of target positioning. Results show that the attitude data obtained by the data reconstruction method meets the accuracy requirements in the mission. |
