the unit vectors are:
for i = 1 .. 3
a(i) = cos(DEC(i))*cos(RA(i))
b(i) = cos(DEC(i))*sin(RA(i))
c(i) = sin(DEC(i))
next i
but before calculating that you need to convert hours to radians and deg to radians using:
for a given value in hours:
Value_in_rad = Value_in_h * PI/12.0
for a given value...
Hello! First I am new at this forum and would like to say hello to everybody :)
Second- I am looking for a good tutorial on artificial Earth satellites orbit perturbations. Can somebody give me an advice where I can find it? Do you know any propagation algorithms for artificial satellites that...
