【摘要】：本文的主要内容是高精度局部重力场计算平台的集成与开发。 目前，针对大地测量，尤其重力数据处理方面的软件虽然并不算少，但是很少见到功能全面的系统性大型软件。为了改善这一状况，课题组研发了高精度局部重力场计算平台。 高精度局部重力场计算平台是一套适用于重力场数据处理、局部重力场逼近和大地水准面精化等方面研究和工程计算工作的软件平台。平台采用面向对象的模块构架，使用Visual C++6.0和Visual Fortran95混合编程开发，功能体系相对独立，用户在使用软件的过程中不需要借助其他工具。 高精度局部重力场计算平台的开发，其意义在于改善科研工作人员的工作效率与方法，提高重力场数据处理的软件水平，填补系统性计算平台软件稀缺的这一空白。平台包含了多项理论技术创新，对传统局部重力场技术和算法进行了大量的改进，能够更加适应厘米级大地水准面精化和高精度局部重力场逼近的新技术要求。 软件是在利用模拟数据基础上开发的，本文重点介绍了集成后的软件功能实现，并通过实测数据对软件进行测试，增强软件的实用性，以期满足工程化应用需求。本文最后总结出软件本身存在的问题与今后再开发可能遇到的问题，并对部分问题提出了解决方案。 课题组自2008年以来，逐渐发展并完善了该软件1.0版本。应技术革新要求，现需要将平台软件结构重新规划后集成开发，并对其功能以及部分接口重新设计。然后对系统整体进行详细的测试，并分析其结果。本论文主要对该软件的集成开发及整合进行介绍。本课题的研究内容为更新软件框架，以及数据接口和人机交互界面，整合归并算法后重新集成计算平台。集成后，由于对软件系统进行了改动，因此需要测试确定其可靠性以及稳定性。本课题中，我们将使用实际数据，，设计整套计算流程，熟悉软件操作并进行软件测试。 测试结果经分析，软件的重新集成后，可靠性和稳定性均能够达到要求水平，能够满足科研与工程任务需要。
[Abstract]:The main content of this paper is the integration and development of high-precision local gravity field computing platform. At present, there are few software for geodesy, especially gravity data processing, but there are few systematic large-scale software with comprehensive functions. In order to improve this situation, a high precision local gravity field calculation platform has been developed. The high precision local gravity field computing platform is a software platform suitable for the research and engineering calculation of gravity field data processing, local gravity field approximation and geoid refinement. The platform adopts the object-oriented module framework, uses Visual C 6.0 and Visual Fortran95 mixed programming development, the function system is relatively independent, the user does not need to use other tools in the process of using the software. The development of high precision local gravity field computing platform is significant to improve the efficiency and method of scientific research staff, to improve the software level of gravity field data processing, and to fill the gap of software scarcity in systematic computing platform. The platform includes many theoretical and technical innovations, and a large number of improvements have been made to the traditional local gravity field techniques and algorithms, which can better meet the new technical requirements of centimeter level geoid refinement and high precision local gravity field approximation. The software is developed on the basis of simulated data. This paper mainly introduces the realization of the integrated software function, and tests the software through the measured data to enhance the practicability of the software in order to meet the needs of engineering application. Finally, this paper summarizes the problems existing in the software itself and the problems that may be encountered in the future re-development, and puts forward some solutions to the problems. Since 2008, the research group has gradually developed and improved the 1.0 version of the software. In response to the requirement of technological innovation, it is necessary to redesign the software structure of the platform after the integration development, and redesign its functions and some interfaces. Then the system as a whole is tested in detail, and the results are analyzed. This paper mainly introduces the integrated development and integration of the software. The research content of this subject is to update the software framework, data interface and human-computer interaction interface, integrate the merging algorithm and re-integrate the computing platform. After integration, the software system needs to be tested to determine its reliability and stability. In this topic, we will use the actual data, design the whole calculation process, familiar with the software operation and software testing. The test results show that the reliability and stability of the software can reach the required level and meet the needs of scientific research and engineering tasks.
