3 dimensional object-oriented, windowed satellite tracking package.
-------------------------------------
Short Description:
-------------------------------------
PC-TRACK is a 3D object-oriented, windowed satellite tracking package.
Tracks up to 300 satellites simultaneously. Provides a colorful, graphical
means of visualizing satellite orbits both in stunning three dimensional
spherical displays and flat map displays. Has integrated mutual
visibility pass scan capability for future in-range passes. Can capture
graphics screen displays to PCX files. Uses SGP4/SDP4 propagation.

Long Description:
---------------------------------
Capabilities
PC-TRACK is a powerful tool, utilizing the latest in object-oriented
technology and double-precision calculations to accurately compute
required data. PC-TRACK is capable of computing:
* Fields of view for any of the earth sites
provided or any user-defined site.
* Positions and velocities for any/all of the
satellites provided and any user-defined
satellites.
* Doppler shifted downlink frequencies
* Viewing angles
* Ranges and range rates.
* Future mutually visible passes and associated data
(including acquisition of signal time (AOS), loss
of signal time (LOS), time in range (TIR), maximum
elevation (MAX EL), and sun illumination.
* Passes illuminated by the sun.
* Satellites visible at a particular time.
Graphics
PC-TRACK takes advantage of the standard VGA 640x480
resolution mode for graphics displays. With any
available mode PC-TRACK is capable of displaying the
following for both tracking and mutual visibility pass
scans:
* Simultaneously the positions of any or all of the
satellites provided or any user defined
satellites.
* Line of site lines from all active sites to all
active satellites.
* Altitude lines for all satellites.
* Visibility footprints for all active satellites.
* Satellite space position (with or without trail)
* Sub-satellite point position (with or without
trail)
* Geographic features of the earth
* Any combination of coasts, islands, countries,
states, rivers and lakes (with MAPGEN, provided to
registered users).
* Latitude and longitude lines.
* Mercator flat map projections.
* Earth Centered Fixed (ECF) 3D projections
* Ground Site viewing angles
* Points of passes illuminated by sun.
* Current tracking date, time and interval as either
UTC or Local time with 3 different date formats
* Site and satellite names
* Metric or English distances
Features
With PC-TRACK you have the latest in satellite tracking
technology for your IBM compatible PC. PC-TRACK provides:
* Runs in DOS Protected mode, which removes the
640K memory barrier. Utilizes up to 16 MB of memory.
* Includes a Dynamic Link Library that contains
SGP4/SDP4 propagation algorithms.
* Complete control over all display attributes
(including those described above), colors, site
and satellite selection to make displays as simple
or detailed as necessary.
* Simple update of orbital elements through direct
import of data from:
NASA/NORAD two-line element files
AMSAT keplerian element files
PC-TRACK 1.x & 2.x object data files
* Multiple "personalities" through the use of
user-defined parameter files which define display
attributes, colors, viewpoints, active sites,
active satellites, etc.
* User friendly menu driven windowed interface.
----------------------------------------
System Requirements:
----------------------------------------
In order to use PC-Track most effectively, you should
have a computer system that has the following features:
CPU any 80386SX, 80386, 80486 processor based system.
(A math coprocessor SIGNIFICANTLY improves performance,
but is not necessary to run.)
RAM 2 - 16 MB
DISK at least 5MB of disk space.
DOS MS-DOS or PC-DOS version 5.0 or greater.
VIDEO VGA Color Video (Required for graphics use. Any lesser video
standard will work using the TEXT track capability).
PRINTER Printer (optional)
MOUSE A mouse will allow you to take advantage of
many convenient features of PC-Track, and is
much easier to use if you have one, but you
can get by without one.
If you do wish to use a mouse, the following
is required for proper operation:
-Microsoft Mouse version 6.1 or later,
or any mouse compatible with this.
-Logitech Mouse version 3.4 or later.
-Mouse Systems PC Mouse version 6.22 or
later.
-IMSI mouse version 6.11 or later.
The mouse driver must be loaded before
running PC-Track.
KEYBOARD A standard 101 key "AT" style keyboard
(sometimes referred to as an "Extended"
keyboard) is recommended.
