The F1 format description

The initial orbital data are distributed in the F1 format, which contains orbital elements as a the state vector (the spacecraft position and velocity vector) in the inertial frame (Standard reference of the Earths Equator and Equinox J2000).

This data set includes the following information:

INT	The Project name
ITZ	The spacecraft name
01	The Format number
0001	The Message number
01	The Number of the message version
00001	The Orbit number
030895	The Date (Day, Month, Year)
011330887	Universal time corrected (hours, min, s, ms)
-001451.596	The spacecraft - (km)
-008276.384	- position - (km)
+000000.000	- vector (km)
+3.35109584	The velocity - (km/s)
-4.23559072	- vector - (km/s)
+7.86668273	- components (km/s)

The F1 format for this data looks as follows:

INT/ITZ/01/0001/01/00001/

030895/011330887/

-001451.596/-008276.384/+000000.000/

+3.35109584/-4.23559072/+7.86668273/

5873/ZZ

The last line contains the checksum and the end of data symbol ZZ.
