Disk No 921 Program Title: ASTRONOMY and AERONAUTICS PC-SIG version 1 This disk contains several useful programs relating to astronomy, earth satellites, and aeronautics. KEPLER is a tutorial program that solves Kepler's equation for elliptic, parabolic and hyperbolic orbits. SIDEREAL is a tutorial program that introduces the user to the relationships between Julian calendar dates and solar and sidereal times. J2000 is a utility program that converts stellar positions, proper motion, parallax and radial velocity from the standard epoch B1950 (FK4) to epoch J2000 (FK5). GALILEAN is a tutorial program that determines the position of the Galilean satellites relative to Jupiter. SYNCSAT and TNODE let you determine the location of several earth-orbiting satellites. This information can be used for radio tracking, communications, and visual observations of earth satellites. ATMOS is a utility program that determines properties of the standard atmosphere. ROCKET1 is a program which determine the flight performance of a single stage model rocket. GLIDER determines the maximum range and maximum endurance flight conditions of boost and rocket gliders. This program is also applicable to sailplanes, hang gliders, and radio-control gliders. Usage: Astronomy / Aeronautics System Requirements: 128K memory and one disk drive. How to Start: Enter the name of the program then (press enter). Suggested Registration: $34.95 ($39.95 foreign) for astronomy disk, $24.95 ($29.95 foreign) for satellite disk, $19.95 ($24.95 foreign) for aeronautics disk.
