XML_GALILEO

The program is designed to convert the Galileo almanac from the XML format to the YUM format.

XML_GALILEO is designed to convert Galileo almanac database code into YUM format. The program reads the almanac, resets old and converts new data, reads it from each satellite and writes it in YUM format.

The program consists of several files:

• XML Date – a folder where untransformed data from the site is stored.
• Out_Dat – the folder in which converted data from the site is written.
• Tim – time function.
• initdata – function of initialization of arrays.
• Galxml – startup file.
• e_norm – mantissa normalization function.

In order to start working with the program, you need:

1. Go to the Galileo website: https://www.gsc-europa.eu/product-almanacs;
2. After going through the «GSC Products – Almanac», select the almanac that needs to be converted to the YUM format;
3. Save the downloaded data to the XML Date folder;
4. Insert the name of the selected almanac into the program code;
5. Specify the folder where the Yum file will be saved.

Using the above method, the Galileo almanac was obtained. For illustration, below is an almanac of one of the Galileo satellites from the database and in YUM format.
