Abstract. Because of the low efficiency data analysis and processing for ship pose and position, A set of ship pose and position data processing software was designed and implemented by MATLAB graphical user interface (GUI). In order to make the interface more layering and operational, we use several separate callback function to realize global callback by relevant with botton-up design methods. The software realize some functions: evaluating the data quality, data graphic outputing, and data tabulated outputting.

Introduction

The space measurement ship is an important part of China's space measurement and control network, which mainly undertakes the offshore measurement and control mission of the target aircraft. Space measurement ship requires inertial navigation systems to measure ship position and attitude information in real time for eliminating measurement errors under dynamic conditions at sea. The position and equipment of Yuanwang 7 Ship include inertial navigation equipment and satellite navigation equipment, navigation console can receive storage inertial navigation, guidance measurement information and status information. Besides, it can also store the raw data of the inertial internal components, and simultaneously receive and store the hull deformation information output by the deformation measuring device.

The posture and position information generated by the navigation equipment and the deformation equipment are with lots of characteristics including lots of types, different storage formats, large amount of stored data, and difficult analysis and processing afterwards. In actual work, there is a large demand for post-processing of ship attitude and ship position data. There are multiple analysis and processing requirements for different data in precision analysis, fault troubleshooting, state determination, data inversion, long-term accumulation comparison and some other time.

At present, the data analysis and processing methods adopted are basically temporary, that is, the programs are written according to different needs every time, the code re-usability is poor, and the analysis processing efficiency is quite low. Therefore, it is necessary and meaningful to design and implement a ship position data analysis and processing software, which is easy to operate, but also comprehensive in analysis and processing data, extensible, and intuitive in visual display.

Software Design

Development Environment Determination

The computing function of MATLAB is powerful, the vector, array, matrix and other operations and file processing functions provided offers convenient conditions for data processing. MATLAB also provides support for graphical user interfaces (GUIs) that visualizes boring programming languages. From the current software trend, a friendly graphical interface can not only make people more acceptable, but also improve efficiency.

A graphical user interface (GUI) is a user interface created by using graphical objects such as buttons, text boxes, scroll bars, menus, and more. The process of implementing a GUI consists of two basic tasks: one is the component layout of the GUI, and the other is the GUI component programming. All of these functions are done through the graphical user interface development environment GUIDE.

This paper is based on MATLAB/GUI user graphical interface development tool implementation.

Interface Design

Analyze the main functions to be realized in each interface, use the series of tools provided by the MATLAB graphical user interface development environment GUI to create the main interface of the concept and each sub-interface, complete the corresponding functions, and ensure the reasonable layout and beautiful interface.

Main Interface Design

Enter any sub-interface by selecting the menu bar through the main interface of the system. Then click the “Exit” button to exit the system.

The menu bar displayed in the main interface is designed by the menu editor. The main interface is shown in Figure 2, and the menu editor is shown in Figure 3.

Sub-interface Design

Taking the inertial navigation 1Hz state data processing interface as an example, briefly explain the sub-interface design. Create a blank MATLAB GUI interface, place the required GUI controls in the appropriate positions, and set the properties of each control,, the interface after setting is shown as in Figure 4.The interface consists of data input and data quality assessment area, drawing selection area, drawing area, description area and some other areas.The interface after running is shown as in Figure 5.

Software Test

According to the function of the designed graphical interface, the user writes a callback function that can implement the function for each different graphic object until can control the input of the data directly through each control on the interface, and can easily and intuitively see the expected results. After the GUI interface is designed, the software needs to be tested, which means a lot of verification is performed to determine that the software can achieve the expected function well. Mainly to improve the writing of callback function code and humanized design such as prompt dialog.

Take the INS 1Hz state data processing interface as an example to test the software.

Import the inertial navigation 1Hz state file through the “Data Import” button, and process the data to give a progress prompt, as shown in Figure 6.After the processing is completed, the data quality is given, mainly is the number of dropped frames and re-frames, as shown in Figure 7.
