摘要：《联合弹药效能手册》（JMEM）由弹药效能联合技术协调小组（JTCG/ME）编制，旨在提供一套数据和方法，以便对所有军种的武器效能进行标准化比较。近年来，JMEM正在被集成到一个单一的软件程序中，使用户能够确定武器系统对特定目标的有效性，而不管武器投放模式如何。作为升级工作的一部分，本文旨在开发一个程序，用Visual C++编写，自动计算精度衰减（DOP）与GPS制导武器系统的投放精度。将程序生成的DOP值与商业DOP计算软件生成的DOP值进行比较，以进行验证。研究了垂直方向DOP与水平方向DOP之间的关系以及利用旧历书信息计算DOP值的效果。发现一颗可见卫星的丢失可能导致DOP增加多达38%。
Abstract : The Joint Munitions Effectiveness Manuals (JMEM) were developed by the Joint Technical Coordinating Group for Munitions Effectiveness (JTCG/ME) to provide a set of data and methodologies that would permit a standardized comparison of weapon effectiveness across all service communities. In recent years, the JMEM are being integrated into a single software program that allows users to determine the effectiveness of weapon systems against a specified target irrespective of the weapon delivery mode. As part of the upgrading effort, this thesis aims to develop a program, written in Visual C++, to automate the calculation of the Dilution of Precision (DOP) associated with the delivery accuracy of GPS guided weapon systems. The DOP values generated by the program were compared with those generated by commercial DOP calculation software for validation. The relationship between the Vertical DOP and Horizontal DOP as well as the effect of using outdated almanac information to calculate DOP values were studied. It was found that the loss of one visible satellite could cause the DOP to increase by as much as 38%.
