*** RENAME EARTHPIC AS EARTHORBIT.PIC ***
This program was written in C.
Some features:
1) The initial values are set for Colorado Springs, CO. The long and
lat and elevation are for the Downtown Post Office. The correction
for Longitude at 38 deg lat is:
1' 06.0" per mile.
The correction at 38 deg lat for Latitude is:
0' 52.2" per mile.
2) The program reads in the orbital elements for some 130 satellites.
The data set is called SATDAT.ED and is updated every 2 weeks on
Compuserve in the astroforum under Satellite Observing.
3) The program provides a Ground Trace for the selected satellite. The
display increments in 2 minute steps. So be watchful of selecting
Ground Trace with a large duration of Prediction.
4) The program accounts for the Earth's oblateness, but not atmospheric
drag.
I hope this program is useful if not at least interesting. If you have
any questions, improvements, comments etc. I'd love to hear from you. I
can be contacted at EPOCH2000 BBS (303)-531-6172 or on Compuserve
72307,3435.
Have Fun!
