Orbiter was developed as a simulator, [14] with accurately modeled planetary motion, gravitation effects (including non-spherical gravity), free space, atmospheric flight and orbital decay. [15] [16] The position of the planets in the solar system is calculated by the VSOP87 solution, while the Earth-Moon system is simulated by the ELP2000 ...
The Space Shuttle Pathfinder (unofficial Orbiter Vehicle Designation: OV-098) is a Space Shuttle test simulator made of steel and wood.Constructed by NASA in 1977 as an unnamed facilities test article, it was purchased in the early 1980s by the America-Japan Society, Inc. which had it refurbished, named it, and placed it on display in the Great Space Shuttle Exhibition in Tokyo.

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.
ASTOS is a tool dedicated to mission analysis, Trajectory optimization, vehicle design and simulation for space scenarios, i.e. launch, re-entry missions, orbit transfers, Earth observation, navigation, coverage and re-entry safety assessments.
FreeFlyer has been used to support many spacecraft missions, for mission planning analysis, operational analysis, or both. Specific mission examples include the International Space Station (ISS), [7] the JSpOC Mission System, [8] the Earth Observing System, [9] [10] Solar Dynamics Observatory (SDO), [11] and Magnetospheric Multiscale Mission (MMS).
The free trading simulator makes TC2000 one of the best stock screeners. You can practice and learn the platform with a basic layout, charts, positions and options chains.
Wall Street Survivor’s real-time simulator works as a stock market game by providing players with $100,000 in virtual cash to buy and sell investments. Investments include stocks, ETFs, options ...
A numerical model of the Solar System is a set of mathematical equations, which, when solved, give the approximate positions of the planets as a function of time. Attempts to create such a model established the more general field of celestial mechanics. The results of this simulation can be compared with past measurements to check for accuracy ...
