This is version 1.2 of ORBIT. The changes made are as follows.
-Time is now displayed as the prediction routine is processing.
-Time, Az, El, GrndTraceLat, GrndTraceLong and visibility are now
displayed on the ground trace frame.
-The Exit and Back functions work at any time, no longer do you have
to wait for the prediction to finish or the ground trace to finish
before you can either exit or backup a frame.
Again thanks for the inputs and I welcome more.

*** 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!

before you can either exit or backup a frame.
Still yet to come:
-Ability to read in the observer's data, ie. station lat, long, el etc.,
as well as time preferences.
-Print capability both for the prediction text and the ground trace.
Again thanks for the inputs and I welcome more.
