【摘要】：就天文測量而言，歷史上T3、T4、J05、DKM3等天文儀器與計時器結(jié)合，完成天文大地測量。天文測量一直存在兩個重要“瓶頸”：一是天文計時設(shè)備適應性差，維修率高，計時器壽命不長，，數(shù)據(jù)采集穩(wěn)定性不高；二是由天文觀測方法決定的，測量方法的設(shè)計更多關(guān)注于使觀測簡單、盡可能減少系統(tǒng)誤差，因而造成觀測時間、星位選擇、環(huán)境要求都很苛刻，使天文測量一直存在觀測任務繁重、計算復雜、效率低下等實際難題。 解放軍測繪學院和總參第一測繪大隊聯(lián)合研制的Y/JGT-01天文測量系統(tǒng)（以下簡稱為“新系統(tǒng)”）很好地解決了上述傳統(tǒng)測量方法的局限性。首先，新系統(tǒng)的實用天文測量理論設(shè)計突破了傳統(tǒng)天文測量方法理論上的局限性；二是基于理論設(shè)計的突破，進而形成觀測方法的“革命性”改進，提高了測量可靠性和精度、減輕了勞動強度、大幅提高了觀測效率。 新系統(tǒng)自2006起裝備我部隊，在正式投入生產(chǎn)作業(yè)前，對該裝備進行了大量的試生產(chǎn)，并與T4天文測量系統(tǒng)為參照目標進行了比對測試，以檢驗新系統(tǒng)的性能。 本篇論文主要研究新系統(tǒng)的試生產(chǎn)及數(shù)據(jù)測試分析及與傳統(tǒng)天文測量系統(tǒng)的比較，以求確定新系統(tǒng)在完整性、可靠性、穩(wěn)定性方面符合天文大地測量的要求，為新系統(tǒng)進入正式作業(yè)生產(chǎn)提供支持。 在新系統(tǒng)測試生產(chǎn)過程中，作業(yè)隊提出了許多建設(shè)性的改進意見。論文在此基礎(chǔ)上，對新系統(tǒng)進行了進一步優(yōu)化完善，改進了交互界面，增加了一些實用功能，實現(xiàn)了軟件對數(shù)據(jù)的正確性檢驗及剔除能力，實現(xiàn)了原始數(shù)據(jù)加密存儲，解決了數(shù)據(jù)安全問題。
[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.
