Projects / BOTEC


BOTEC is a simple but useful calculator that assists with astrophysical, orbital mechanics, and space navigation calculations. It is a "back-of-the-envelope calculator" rather than an industrial-strength calculator, although this may change in the future. It is primarily intended for people familiar with physics and Python, and as such is unlikely to be useful to the average end user. It includes solar system data, and all values are strictly in SI units.
