Generation of TLE
The exponent in the generated 2-line element may not contain more than one character.
from: http://celestrak.com/columns/v04n03/
"Fields 1.10 and 1.11 have a somewhat different format that the other
fields. In particular, they use a modified exponential notation with an
implied leading decimal point. This convention is inherited from FORTRAN
where all such numbers range from 0 to less than 1. The first six
columns of each field represent the mantissa and the last two represent
the exponent. For example, the value -12345-6 corresponds to -0.12345 ×
10-6. Each of these two fields can be blank, corresponding to a value of
zero."
File TLE.java row 319 and on.
Now generates first line for example:
1 05555U 00001A 12026.66666667 2.82387199 13028-11 -76213-5 0 15
