# FAST **Repository Path**: hhdych_admin/FAST ## Basic Information - **Project Name**: FAST - **Description**: FAST 针对目前GNSS数据下载步骤繁琐、下载速度慢等问题，开发了一套较为完备的融合多源数据下载终端软件——FAST。 软件目前包含GNSS科研学习过程中绝大部分所需的数据源，采用并行下载的方式极大的提升了下载的效率 - **Primary Language**: Python - **License**: MulanPSL-2.0 - **Default Branch**: main - **Homepage**: None - **GVP Project**: No ## Statistics - **Stars**: 0 - **Forks**: 17 - **Created**: 2024-11-08 - **Last Updated**: 2024-11-08 ## Categories & Tags **Categories**: Uncategorized **Tags**: None ## README # FAST （Fusion Abundant multi-Source data download Terminal） ####Introduce **FAST** Aiming at the problems of cumbersome steps and slow download speed of GNSS data, a relatively complete set of integrated multi-source data download terminal software fast is developed. The software contains most of the data sources required in the process of GNSS scientific research and learning. The way of parallel download greatly improves the efficiency of download. #### Git - [https://github.com/ChangChuntao/FAST](https://github.com/ChangChuntao/FAST) - [https://gitee.com/changchuntao/FAST](https://gitee.com/changchuntao/FAST) #### Software features - **Multi platform**: Support both windows and Linux systems; - **Abundant Resources**: It basically includes the data sources required in GNSS scientific research and learning. At present, it supports 17 categories and 96 subcategories. See the specific **Data support**; - **Fast**: The software adopts parallel download mode, and the number of download threads can be specified in the command line parameter operation mode. After testing, it only takes 48.93s to download the 100 days BRDC+IGS+CLK file! - **Easy to expand**: If you need to support more data sources, you can specify the required data and data sources in FTP_Source.py and GNSS_TYPE.py; - **Easy to run**: The program can be downloaded in two ways: boot download mode and terminal input mode with parameters. Run the program directly to enter the boot download mode. Run `FAST -h` on the terminal with parameters to view the introduction of operation mode with parameters; - **Flexible**: In the operation mode with parameters, users can flexibly specify the download type, download location, download time, whether to decompress, number of threads, etc., and can write scripts such as bat, shell and python to run according to their own needs; - **Portable**: the windows package is only 18.9 MB, and the Linux package is only 6.63 MB #### Installation tutorial - **Windows**you only need to unzip the package to run directly, enter `FAST.exe -h` can view the introduction of operation mode with parameters; - **Linux**you only need to unzip the package to run directly：After installation, as under Windows system, you can directly run the program or configure the program to environment variables. #### Instructions **Boot Download Mode**: In Windows system, click run fast Exe can enter the boot download. If it is a Linux system, the terminal can enter `FAST` to run; 1. Take downloading the multi system precise ephemeris of Wuhan University as an example, select SP3 in the primary selection directory, enter 2 and press enter； ![一级目录](Support/RUN_image/whuSp3-1.png) 2. Select MGEX_WUH_SP3 is input 6 and enter, where MGEX represents multi system GNSS, WHU represents Wuhan University, IGS data processing center and SP3 represents precision ephemeris; ![二级目录](Support/RUN_image/whuSp3-2.png) 3. Enter the time according to the prompt and press enter to complete the input; ![输入时间](Support/RUN_image/whuSp3-3.png) 4. After the download is completed, press enter directly according to the prompt to complete the decompression, or press enter without decompression; ![下载完成](Support/RUN_image/whuSp3-4.png) 5. Enter y or exit again according to the prompt; ![在此引导](Support/RUN_image/TYPE1-again.png) **Terminal input mode**: In Windows system, run `FAST.exe -h` in CMD or power shell software to view the help. If it is a Linux system terminal, enter `FAST -h` to view the help; ``` FAST : Fusion Abundant multi-Source data download Terminal ©Copyright 2022.01 @ Chang Chuntao PLEASE DO NOT SPREAD WITHOUT PERMISSION OF THE AUTHOR !
