Keplerian

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

The Ejs Keplerian Orbit model displays the dynamics of a mass orbiting a much larger mass subject to Newtonian gravity. The simulation displays the motion of the smaller mass and the effective potential energy diagram. The initial energy of the system can be changed via textbox and the initial... Platforms: Mac

Phi = keplerSTM(x0,dt,mu) will return the state transition matrix Phi for a set of objects described by initial positions and velocities (x0) with gravitational parameters mu, propogated along Keplerian orbits for time dt. The positions and velocities at time dt is then given by Phi*x0. x0 must... Platforms: Matlab

Convert orbital elements to a state vector, or a state vector back to orbital elements.Most readily available Keplerian orbital element conversion utilities do not address circular or parabolic orbits. This set of routines will address the complete spectrum of orbits from a circular equatorial... Platforms: Matlab

Keplerian orbits, elliptical, parabolic, hyperbolic orbits, elements conversion. Temporal problem, mean anomaly, eccentric anomaly, true anomaly. MOID. Orbits plot. Position and velocity vectors.Orbital maneuvers: Lambert problem solution, delta-v computation, optimal time-free orbital transfer,... Platforms: Matlab

MacDoppler for Cocoa was re-written from the ground up to take full advantage of all the great Cocoa capabilities in OS X on PPC as well as Intel hardware. MacDoppler will provide any level of station automation you need from assisted Doppler Tuning and Antenna Pointing right on up to fully... Platforms: Mac

Halley is a handy application that allows you to access and get various informations about comets. Works with the comets database, containing Keplerian orbital elements, non-gravitational and physical parameters of the comet, and other data. The database is updated in case the new data become... Platforms: Windows, Windows Vista, 7

vec2orbElem(rs,vs,mus) converts positions (rs) and velocities (vs)of bodies with gravitational parameters (mus) to Keplerian orbital elements.INPUTS: rs: 3n x 1 stacked initial position vectors: [r1(1);r1(2);r1(3);r2(1);r2(2)r2(3);...;rn(1);rn(2);rn(3)] or 3 x n matrix of position vectors. vs: 3n...
