Orbit Lawn Sprinklers

Calculation of orbital elements from position end velocity of satellite according to Keplerian lows.Calculation of six Keplerian elements wich represent orbit.

A modified version of the SGP4 code used for standard satellite orbit computation using two-line elements (TLE). The modified code outputs satellite positions and velocity in ECF coordinates and universal time from EPOCH. Utilities are provided to calculate point-to-point angle, range rates, TCS...

The Geostationary Earth Orbit Satellite Model is a simple angular velocity model that uses Java3D for a realistic visualization of satellites in geostationary orbits. Students can view and explore the behavior of geostationary orbits, non-geostationary orbits, and non-physical orbits. This model...

There are 23 different functions performing basic orbital operations (Hohmann tx, inclination and node changes, orbital parameter conversions, ground tracks, orbit plotting, etc.). Some of these functions are still rough, so please provide feedback. These functions are basically how I did all of...

Given mean anomaly and eccentricity of an orbit, eccentric anomaly can be calculated using Kepler's Equation. However, the equation is nonlinear, and an iterative technique must be used. This program uses a fixed-point iterative technique to output eccentric anomaly to a user defined tolerance,...

Both of us were busy during Pyweek 8, so we made a rather small game. To our own surprise, it turned out to be a quite fun and complete game. This is a top-down zombie-shooting game where you get experience points for shooting zombies. After each levelup you gain a random perk (faster movement,...
