【摘要】：就天文测量而言，历史上T3、T4、J05、DKM3等天文仪器与计时器结合，完成天文大地测量。天文测量一直存在两个重要“瓶颈”：一是天文计时设备适应性差，维修率高，计时器寿命不长，，数据采集稳定性不高；二是由天文观测方法决定的，测量方法的设计更多关注于使观测简单、尽可能减少系统误差，因而造成观测时间、星位选择、环境要求都很苛刻，使天文测量一直存在观测任务繁重、计算复杂、效率低下等实际难题。解放军测绘学院和总参第一测绘大队联合研制的Y/JGT-01天文测量系统（以下简称为“新系统”）很好地解决了上述传统测量方法的局限性。首先，新系统的实用天文测量理论设计突破了传统天文测量方法理论上的局限性；二是基于理论设计的突破，进而形成观测方法的“革命性”改进，提高了测量可靠性和精度、减轻了劳动强度、大幅提高了观测效率。新系统自2006起装备我部队，在正式投入生产作业前，对该装备进行了大量的试生产，并与T4天文测量系统为参照目标进行了比对测试，以检验新系统的性能。本篇论文主要研究新系统的试生产及数据测试分析及与传统天文测量系统的比较，以求确定新系统在完整性、可靠性、稳定性方面符合天文大地测量的要求，为新系统进入正式作业生产提供支持。在新系统测试生产过程中，作业队提出了许多建设性的改进意见。论文在此基础上，对新系统进行了进一步优化完善，改进了交互界面，增加了一些实用功能，实现了软件对数据的正确性检验及剔除能力，实现了原始数据加密存储，解决了数据安全问题。
[Abstract]:As far as astronomical measurement is concerned, astronomical instruments such as T _ 3N T _ 4T _ 4N _ J _ 05N DKM _ 3 have been combined with timers to complete astrogeodesy in history. There are always two important "bottlenecks" in astronomical measurement: one is the poor adaptability of astronomical timing equipment, the high maintenance rate, the short life of timer, and the low stability of data acquisition; the other is determined by astronomical observation methods. More attention has been paid to the design of measurement methods to make observation simple and to reduce the systematic error as much as possible. As a result, the observation time, satellite position selection and environmental requirements are very demanding, which makes astronomical measurements always have heavy observation tasks and complicated calculations. A practical problem such as inefficiency. The Y/JGT-01 astronomical measurement system (hereinafter referred to as "the new system") developed jointly by the PLA Institute of surveying and Mapping and the first surveying and Mapping Group of the General staff has solved the limitation of the traditional measuring methods mentioned above. First, the practical astronomical measurement theory design of the new system breaks through the limitation of the traditional astronomical measurement method, the second is the breakthrough based on the theoretical design, and then the "revolutionary" improvement of the observation method is formed, which improves the reliability and accuracy of the measurement. The labor intensity is reduced and the observation efficiency is greatly improved. The new system has been equipped with our army since 2006. Before it was formally put into production, a large number of trial production of the equipment was carried out, and compared with the reference object of T4 astronomical measurement system, the performance of the new system was tested. This paper mainly studies the trial production, data test and analysis of the new system and its comparison with the traditional astronomical survey system, in order to determine that the new system meets the requirements of astrogeodesy in terms of integrity, reliability and stability. Provide support for new system entry into formal production. During the testing and production of the new system, the job team put forward many constructive suggestions for improvement. On this basis, the new system has been further optimized and perfected, the interactive interface has been improved, some practical functions have been added, the ability of the software to check and eliminate the correctness of the data has been realized, and the original data encryption storage has been realized. The problem of data security is solved.
