基于MVC的GNSS验证系统授时指标软件设计与实现

为了方便分析GNSS验证系统授时指标,设计并实现了授时指标软件。该软件具有数据解析、授时载波频率准确性分析、载波频率稳定性分析、码载一致性分析、数据拟合、频域分析等功能。采用MVC(model-view-controller)模式对软件的系统架构进行设计,描述了Qt的信号与槽机制和核心模块的设计及其交互,并用C++语言在Qt平台完成了软件的开发。实验表明,该软件可方便地实现GNSS验证系统授时指标的定量分析,GNSS验证系统频率准确度为10~(-10)、码载一致性为10~(-10)。

Design and Implementation of Timing Indicator Software for GNSS Verification System Based on MVC

In order to facilitate the analysis of the timing indicators of GNSS verification system, the timing indicator software was designed and implemented. The software has functions such as data analysis, timing carrier frequency accuracy analysis, carrier frequency stability analysis, code load consistency analysis, data fitting, and frequency domain analysis. The MVC (Model-View-Controller) mode was used to design the system architecture of the software. The design and interaction of the signal and slot mechanism of Qt and core module are described. The software development was completed on the Qt platform by C++ language. Experiments show that the software can easily realize the quantitative analysis of the timing indicators of GNSS verification system, and the GNSS verification system has a frequency accuracy of and a code carrier consistency of .
