【摘要】：隨著衛(wèi)星導航技術的不斷發(fā)展，衛(wèi)星導航產品在越來越多的領域得到應用，，近幾年我國衛(wèi)星導航系統(tǒng)建設也在緊鑼密鼓的推進，用戶設備的研制和生產得到極大的促進，但設備性能卻良莠不齊。為保障用戶設備行業(yè)健康、快速發(fā)展，建立一套嚴格的設備測試規(guī)范，并科學準確的完成對用戶設備工作性能的評價意義重大。 本文首先介紹了衛(wèi)星導航接收機測試系統(tǒng)的基本構成和工作方式，并針對GNSS基本型接收機主要性能指標的測試方法進行了相關研究。通過分析兩種不同工作方式下的接收機的工作原理，以及各個測試項目與接收機性能之間的關系，分別對RNSS的靈敏度、測距碼捕獲時間、測距精度、首次定位時間、多通道時延一致性、定位測速精度、自主完好性測試以及RDSS的誤碼率、雙向零值和測距精度、定位功能、定位成功率、通信功能以及位置報告功能等進行分析，研究了各項指標的測試方法，并對測試過程中產生的數據進行預處理，分析評估測試結果的方法并制定測試流程。在此基礎上，利用SQL2000建立了測試系統(tǒng)數據庫，并在C#.NET平臺上開發(fā)了用戶設備測試數據評估軟件，實現(xiàn)了自動批量對用戶設備的評估計算。
[Abstract]:With the continuous development of satellite navigation technology, satellite navigation products have been applied in more and more fields. In recent years, the construction of satellite navigation system in our country has also been vigorously promoted, and the development and production of user equipment have been greatly promoted. But the performance of the equipment is mixed. In order to ensure the healthy and rapid development of the user equipment industry, it is of great significance to establish a set of strict equipment testing standards, and to scientifically and accurately complete the evaluation of the working performance of the user equipment. In this paper, the basic structure and working mode of the satellite navigation receiver test system are introduced, and the test methods of the main performance indexes of the basic GNSS receiver are studied. By analyzing the working principle of the receiver under two different working modes and the relationship between each test item and the performance of the receiver, the sensitivity of the RNSS, the acquisition time of the ranging code, the ranging accuracy, the first positioning time, respectively, are analyzed. Multi-channel delay consistency, location-velocity measurement accuracy, autonomous integrity test, bit error rate of RDSS, bidirectional zero value and ranging accuracy, location function, location success rate, communication function and position reporting function are analyzed. The test methods of each index are studied, and the data generated in the test process are preprocessed, the method of evaluating the test results is analyzed and the test flow is established. On this basis, the test system database is established by using SQL2000, and the evaluation software of user equipment test data is developed on the C#.NET platform, which realizes the automatic batch evaluation and calculation of user equipment.
