Accurate calculation:
If you want to be precise, you'll have to use the formula below. Is it worth a 28 second burn? Maybe! There is some beauty in a precise trajectory, but such complexity may be useless sometimes. You decide. The complete formula is as follows: Rough Launch Azimuth = arcsin (cos (desired_orbital_inclination) / cos (launch_ latitude)) Real Launch Azimuth = atan(tan(Rough Launch Azimuth) - SpeedOnEarth/(FinalOrbitVelocity* cos(Rough Launch Azimuth)))
