	This program computes data for the tracking of polar orbiting
sattelites.
	Its main use is for the Amateur Radio operator who uses the several
amateur sattelites which are in polar orbits.

			   Required inputs
	The program will ask for data with which to initialize computation.
This data is available from the American Radio Relay League in their monthly
magazine 'QST'. Other data required will be the operators latitude and longi-
tude.  And time of day in GMT.

				Outputs
	There are two forms of output from the program.

	1. Fast mode: No data is displayed on the CRT. The printer will display
minute by minute data for a period of time set by the user. This will allow the
operato operator to see if the sattelite will be in access range at a time that
he will be at the radio.

	2. Slow or regular mode: All data is displayed on screen as text and a
graphic overlay of the United States. The position of the sattelite is displ-
ayed and updated on the minute. When the sattelite position is within 10
degrees of the operator longitude an alarm is sounded, alerting the operator.

				Notes

	The timing of the program is noted with a remark statement. If your
timing is not quite right then change the wait loop.
