XW-2 First pass over my ground-station 19-09-2015 07:17:59 CEST
It seems that the checksum of the first line of your TLE file is erroneous.
For me, the line should ends with the number 2 (and not 0).
Have you added +1 for the – character ? It looks like not ?

Hi Gabriel,
I had a similar problem, the one in research.txt seems to solve the check-sum problem.
Give it a try and let me know if it also works for you.

hello
Same problem with your research.txt.
The checksum of the first line of XW-2 is erroneous.
The last character of the line must be a “2”, not a zero !
All the others satellite TLE are good but the XW-2 is not OK.
Remember how the checksum of is computer :
– Add all the figures of the lines except the last one which is the checksum
– Add +1 for the sign “-”
– Add +2 for the sign “+”
– Nothing for the other characters (letters …)
– Keep the unit figure of the result ( x modulo 10).
– The 69th character of the line must be equal to this figure.
From where did you get this TLE of XW-2 ?
Gabriel
Update: New launch window and new TLE data.
