PC-TRACK VERSION 3.0
=================================================================
What is PC-TRACK?
PC-TRACK is a simple but sophisticated means of tracking
earth orbiting satellites. PC-TRACK is capable of tracking up to
200 satellites simultaneously in 3D or on a flat mercator
projection!
PC-TRACK is useful to amateur radio and weather satellite users,
science teachers, experimenters, and serious satellite users.
Use it for demonstrating orbital mechanics, predicting
availability times, making presentations, performing satellite
constellation studies, and general orbital analyses. PC-TRACK
uses satellite data readily available from NASA and other
sources.
PC-TRACK offers the following features.
PROGRAM FEATURES
- Runs in DOS protected mode, utilizing up to 16MB of memory.
- Can track in 3D on spherical world projections.
- Uses 640x480 VGA resolution.
- Can track up to 200 satellites simultaneously.
- Text screen tracking for users with no VGA capability.
- Integrated Mutual Visibility Pass Scan capability.
- Scan for visible passes
- Scan all satellites to find illuminated sats.
- Rapid graphics screen redraw.
- Informative satellite position display.
- All colors and parameters user definable.
- Capable of having separate parameter files for
different track/display scenarios.
- Quick start-up.
- Downlink frequency displays, showing doppler shift.
- Display orbital phase, based on current mean anomaly.
- Multiple maps of world and continents available.
- Can be configured to track using UTC time or LOCAL time
- Can be configured to display distances using metric or english system.
- Full control of Date, Time, and Interval used to predict object data.
- Site and Satellite data sorted by name.
- Can store data for up to 200 objects and 200 observers.
- Includes import capability for NASA 2 line Orbital Elements or
AMSAT data files.
- Select from over 100 printer drivers.

WHAT YOU NEED...
In order to run properly, PC-TRACK needs...
■ any 80386SX, 80386, 80486 processor based system.
(A math coprocessor SIGNIFICANTLY improves performance,
but is not necessary to run.)
■ 2 - 16 MB
■ at least 3MB of disk space.
■ MS-DOS or PC-DOS version 5.0 or greater.
■ VGA Color Video (Required for graphics use. Any lesser video
standard will work using the TEXT track capability).
■ Printer (optional)
■ The operational files included on the Distribution Disk.

R U N N I N G P C - T R A C K
========================================================================
Assuming the installation went without problems...
A] Review the QUIKSTRT.DOC (in the .\DOCS subdirectory)
file for some tips for getting familiar with the program quickly.
B] Print The Users Guide...
We recommend that you print out the users guide provided on the
distribution disk. It is installed in the .\DOCS subdirectory.
It explains how to use PC-TRACK. To print out the PC-TRACK User Guide,
just type:
COPY USRGUIDE.DOC PRN <RETURN>
or
PRINT USRGUIDE.DOC <RETURN>
C] Start PC-TRACK by typing
PCT3 <RETURN>
NOTE:
If installation proceeded correctly, the installation program
will have left you in the directory into which PC-TRACK was
installed. At other times you will have to CD to the directory
before running the program.
D] Read the additional documentation for the product in the .\DOCS
subdirectory.
========================================================================
Known Problems With PC-Track 3.0
========================================================================
This application utilizes the DOS Protected Mode Interface (DPMI)
protocol. This means it runs in Protected mode, which is a CPU mode
that permits programs to access ALL available extended memory in your
computer, not just a portion of the 640K conventional memory like
most of the other programs you may be running.
This has caused problems on a handful of systems. For complete
information regarding this, see PROBLEMS.DOC.
