AA_51.ZIP 154200 11-27-95 AA 5.1 computes the orbital positions of
| planetary bodies and performs rigorous
| coordinate reductions to apparent geocentric
| and topocentric place (local altitude and
| azimuth). It also reduces star catalog
| positions given in either the FK4 or FK5
| system. C source code is included. (Steve
| Moshier) (Reg.Fee: $0)
APRTRAK.ZIP 693565 06-10-96 APRtrak provides a mechanism for plotting
| the positions of stations and objects world
| wide based on both lat/long and grid square.
| It evolved from the APRS (Automatic Packet
| Reporting System) software which is a packet
| program for tracking mobiles using GPS units
| interfaced to standard AX.25 packet radios.
| The objective of APRtrak is to provide this
| same tracking and plotting capability for
| spacecraft and satellite ground stations. Not
| only does APRtrak satisfy the inherent
| curiosity that all amateur radio operators
| have about the locations of other stations,
| but it also helps newcomers to radio
| visualize the three dimensional and
| geographic aspects of satellite
| communications. (Reg.Fee: $0)
FLYBY.ZIP 129315 04-02-96 FlyBy 1.0 determines the patched-conic
| gravity-assist interplanetary trajectories
| between any three planets of our solar
| system. Patched-conic gravity-assist
| trajectories are useful for preliminary orbit
| design. The program is driven by simple
| user-defined name lists of information which
| can include departure, flyby and arrival
| planets, the launch calendar date, and grid
| search parameters. (C. David Eagle) (Reg.Fee:
| $0)
G3BODY.ZIP 33357 04-02-96 G3Body 1.0 simulates the motion of a space
| craft in the Earth-Moon system, based on the
| solution of three-body problems. (C. David
| Eagle) (Reg.Fee: $0)
GENTRA.ZIP 281309 04-02-96 Gentra 1.0 performs generalized trajectory
| analysis. It can calculate orbital parameters
| such as flight path angle, geodetic
| coordinates, perigee and apogee altitudes and
| velocities, solve Kepler equations for
| elliptical orbit, convert between Julian
| dates and Universal time, and more. (C. David
| Eagle) (Reg.Fee: $0)
GRMOTION.ZIP 32797 04-02-96 GRMotion 1.0 displays the relative motion
| between two satellites in circular orbits.
| (C. David Eagle) (Reg.Fee: $0)
GRNDTOUR.ZIP 169298 04-13-94 GrandTour simulates space as seen from the
| Voyager and Giotto spacecraft. It also
| generates scenes from arbitrary points in
| space or the Earth, with the spacecraft
| visible to the observer. The planet, moons,
| and rings of interest (or comet, nucleus, and
| tail), stars, the sun, and the spacecraft are
| all accurately drawn with wireframe
| representations. Hidden line removal is done
| for the body surfaces. For color EGA/VGA
| devices, stars are color coded according to
| spectral type. (John D. Callahan) (Reg.Fee:
| $12)
IPTO.ZIP 119325 04-02-96 Interplanetary Trajectory Optimization 1.0
| determines the patched-conic interplanetary
| trajectory between any two planets of our
| solar system. A patched-conic trajectory
| ignores the gravitational effect of both the
| launch and arrival planets on the trajectory.
| The solution is based on solving Lambert's
| problem relative to the sun. Patched-conic
| trajectories are suitable for preliminary
| mission design. (C. David Eagle) (Reg.Fee: $0)
KOMS300.ZIP 91070 12-30-95 Komsoft 3.0 is a database for comet watchers.
| It contains orbital elements of several
| comets, a program to calculate precise
| positions, functions to calculate the
| diameter of astronomical images, support for
| comet observation formats published by IAU,
| and more. Sample comet observations are
| included. (Stefan Beck) (Reg.Fee: $20-25)
NPOE.ZIP 669478 04-02-96 Numerical Prediction of Orbital Events 1.0
| models important orbital events and predicts
| the long term evolution of satellites in
| earth orbits. It can accurately predict the
| time, geometric, and dynamic orbit
| characteristics for any user-defined value
| including true anomaly, argument of latitude,
| geocentric declination, geodetic altitude and
| latitude, orbital speed, and more. It can
| also determine the time and orbital
| characteristics of discrete events such as
| ascending and descending node crossings, rise
| and set conditions of a satellite relative to
| a ground site, and visibility conditions of
| the sun or moon relative to a satellite. A
| pair of companion graphics programs is
| included to plot data and save it to PCX
| format. (C. David Eagle) (Reg.Fee: $100)
OOTA.ZIP 308353 04-02-96 Optimal Orbital Transfer Analysis 1.0
| determines the optimal one or
