Environment

General atmospheric profiles such as ISA, COESA; nonstandard day simulations; lapse rate atmosphere; pressure altitude

Use environment-standards-based reference models to model standard atmospheric, gravity, and magnetic field profiles. Use ephemeris data to calculate position and velocity of celestial bodies.
