Environment

Model general atmospheric profiles such as ISA, COESA; nonstandard day simulations and calculate flow relations, such as isentropic, normal shock, Rayleigh, Fanno, and Prandtl-Meyer

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

Calculate flow relations for Fanno lines, isentropic, normal shock, Prandtl-Meyer functions.
