Thank you BobG, I believe this will do!

Greetings! I would like to know how to calculate the time, or fraction of orbital period, that a satellite spends in umbra? (total solar eclipse for satellite when they aren't affected by Solar radiation pressure and solar panels don't generate power). Information given would be satellite's...

That's right, and Wikipedia is not the only source that says there is no difference. But to quote Vallado ( Fundamentals of Astrodynamics and Applications ), which quotes "Space Vehicle Design" : "Astrodynamics is the study of the motion of man-made objects in space, subject to both natural and...

Hello all. The title of this thread sums up my question - what is the difference between orbital mechanics and astrodynamics ? Or is there a difference at all ? I have sometimes seen different uses of the terms, for example, on many sites I see " astrodynamics or orbital mechanics is ... " ...

After doing more "experiments", it seems that the particular TLE I used was erroneous. This was my first testing of SGP4, and many things could be wrong with the code itself, so obviously, the TLE I got from online source wasn't the first thing I blamed for the errors. It seems that even...

Thank you for reply ! My question is very very specific, so I knew posting it is quite a long shot. I have found a partial answer - the code distribution contains a "testcpp.cpp" file which provides a case of implementation. Using it is fine for start, but being a test example it has...

Greetings all ! I have this problem with SGP4 propagation, that I hope someone can help me out with. I acquired a TLE of the ISS from internet and used the C++ SGP4 propagator to compute future position and velocity vectors of the Station. I am unsure about some aspects of results though and...

Greetings all ! I really hope this is the right sub-forum for my question, I have chosen it because I've seen TLE being mentioned a couple of times around here. I have done some reading on astrodynamics and orbital mechanics, but I am relatively new to coding. I would like to write some C++...

Thank you for the answer. My question was more application oriented though, trying to find already written software. Nonetheless, I have found a library which includes a Runge-Kutta-Fehlberg(78) method. Can anyone explain me the main differences if I would be using the "RKF78" instead of...

Greetings all ! This is my first post on the forum, so please kindly let me know if I am not asking a proper question or on a proper board. I would like to use Runge-Kutta 8th order method (89) in a celestial mechanics / astrodynamics application, written in C++. Therefore I wonder if...
