Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets, satellites, and other spacecraft. The motion of these objects is usually calculated from Newton's laws of motion and the law of universal gravitation .
Orbit modeling is the process of creating mathematical models to simulate motion of a massive body as it moves in orbit around another massive body due to gravity.Other forces such as gravitational attraction from tertiary bodies, air resistance, solar pressure, or thrust from a propulsion system are typically modeled as secondary effects.
Final v s, θ s and r must match the requirements of the target orbit as determined by orbital mechanics (see Orbital flight, above), where final v s is usually the required periapsis (or circular) velocity, and final θ s is 90 degrees. A powered descent analysis would use the same procedure, with reverse boundary conditions.
Orbiter is a space flight simulator program developed to simulate spaceflight using realistic Newtonian physics.The simulator was released on 27 November 2000; [2] the latest edition, labeled "Orbiter 2016", was released on 30 August 2016, the first new version of the simulator since 2010. [3]
The game/program SpaceEngine includes a realistic space flight simulator within its full scale representation of the universe (including both real and procedurally generated astronomical objects), utilizing realistic orbital mechanics and an atmospheric model for certain flyable shuttles.
Electrons in an atom are sometimes described as "orbiting" its nucleus, following an early conjecture of Niels Bohr (this is the source of the term "orbital"). However, electrons don't actually orbit nuclei in any meaningful sense, and quantum mechanics are necessary for any useful understanding of the electron's real behavior. Solving the ...
SpaceEngine also has a built-in flight simulator (currently in Alpha) which allows for users to spawn in a selection of fictional spacecraft which can be flown in an accurate model of orbital mechanics and also an atmospheric flight model when entering the atmospheres of the various planets and moons.
Systems Tool Kit (formerly Satellite Tool Kit), often referred to by its initials STK, is a multi-physics software application from Analytical Graphics, Inc. (an Ansys company) that enables engineers and scientists to perform complex analyses of ground, sea, air, and space platforms, and to share results in one integrated environment. [1]
