Data
Every receiver obtain an ID for naming the data files. For example the DLR_School_Lab in Neustrelitz has the ID "NZ1". By this (and a look-up-table) you get the information about the location of every single receiver. We use the ID as the ending of the file. Furthermore you can find the information about the date of receiving in the name. For this we follow the pattern of:
yyyymmdd (y-year, m-month, d-day).
For example a data file can have the name:"20100101.NZ1". So we know it was received on the 1st of January 2010 in the DLR_School_Lab Neustrelitz.
Content of the Data
UTC: 1 12209 00:00:15
2209 00:00:20
2262 00:00:25
2258 00:00:29
A SOFIE-datafile looks like this. In the first line you find some information regarding UTC, Greenwich. In this example the first "1" tells you, that the receiver is located eastern from Greenwich (true). If not, you would see a "0" (false). The second "1" tells you the time difference between receiver and Greenwich. Daylight savings time isn't considered.
Following the file head, you see the measurements of the signal strength (in millivolts) and the corresponding timestamp (hour: 0-23).
