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.
FAST -h
on the terminal with parameters to view the introduction of operation mode with parameters;FAST.exe -h
can view the introduction of operation mode with parameters;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;
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;
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;
Enter the time according to the prompt and press enter to complete the input;
After the download is completed, press enter directly according to the prompt to complete the decompression, or press enter without decompression;
Enter y or exit again according to the prompt;
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;
