The Satellite Visualization Tool Release Two
=====================================================================

The SVT is a powerful tool, utilizing the latest in object-oriented 
technology and double-precision calculations for accurate predictions 
and analysis. The SVT actually has three major tools integrated into 
one powerful application:

ANIMATED TRACKING

This provides the capability to display satellite positions, sensor 
coverage, solar illumination, target visibility, and other source- 
target relationship information in an animated fashion.  This 
animation may be done in real time, or may be accelerated over time 
to rapidly show positional and relationship changes.

Special site display windows are available to be used with a 
specified ground site. These windows show both graphically and 
numerically the current look angles, rise/set status and solar 
illumination status for all visible satellites. For constellations of 
more than 4 satellites, it will show Dilution Of Precision values for 
the currently visible targets. This is useful for GPS users who need 
positional reliability information for GPS geolocation data.


ORBIT, SITE, AND SENSOR VISUALIZATION

This provides the capability to visually analyze the orbits of single 
or multiple satellites and their sensor coverages in an Earth 
Centered Inertial view frame. It can also show the positions and 
sensor coverage of single or multiple ground sites in either 3D Earth 
Centered Fixed view frame or on selected mercator projection flat map 
displays.

The orbit displays can show single orbits or up to 9 propagated 
orbits for any number of revolutions up to 999999 past epoch. Each 
orbit displayed can show the Node point, Mean Anomaly point, Apogee 
point, Perigee point, and the Epoch point. Multiple satellite orbit 
displays show the relationships of orbits in a constellation.

For single satellite displays, keplerian data for the first and last 
revolution data can be displayed numerically on screen along with the 
graphical view. Sensor coverage for the satellite can also be 
displayed for any point along the orbit, and solar position/
terminator line can be displayed to show solar beta angle graphically.

The site displays can show in 3D the site position and the area in 
space covered by the sensor. 11 different mercator projections maps 
are available to display site locations. Also available for a site 
display is a sky view, shown for a user selected date and time. This 
display shows either the sun and moon for day or moon and stars for 
night, along with the sensor coverage area, and a azimuth/elevation 
grid.

PASS SCANNING AND ANALYSIS 

This provides the most powerful analysis tool in the product. With 
this tool, you can search for, display, visualize, print, and export 
source/target relationships over a specified period of time using a 
specifed search criteria.

An exclusive feature of SVT is the abilty to do time correlated 
scans, which will find time segments in which ALL designated source/ 
target positions and relationships meet the search criteria. This is 
powerful feature which permits analysis of sophisticated multiple 
source/target scenarios. 

For example, you can determine the times when ground site A can see 
relay satellite B, and when relay satellite B can what elements of 
satellite constellation C, containing multiple satellites, and when 
ground site D can see relay satellite B.

Data can be displayed using a variety of coordinate systems, units of 
measure, and display formats. Computed data and subsets thereof can 
be selectively displayed and analyzed. 

For any particular scan operation the following may be specified: 

 o  Time period of the scan.
 o  Resolution of (time between) time points.
 o  Source and target objects (any number).
 o  Filter (search) criteria.

During a scan operation, the positions of and relationship between 
each source/target pair are computed for each time point within the 
time period. The time between each time point is specified by the 
resolution. Each time point meeting the filter criteria is added to a 
time segment, with statistics and summary information for that time 
segment being automatically calculated. 

With data collected during a scan, the following may be done:  

 o Display summary information for each time segment including:   
  o Source and Target names
  o Duration of time segment.
  o Increment (resolution)
  o Time point data for the following statistical points:     
    o Start, Mid & Stop points
    o Minimum Elevation point     
    o Maximum Elevation point     
    o Minimum Range point     
    o Maximum Range 
    o Minimum Range Rate point     
    o Maximum Range Rate point 

 o Select multiple time segment summaries to: 
    o Visualize in 3D or on mercator projections
    o Compute and display Dilution of Precision 
       (DOP) values for GPS analysis     
    o Display a time correlation graph of time relationships 
      between segments.     
    o Print     
    o Export   
    o Select a single time segment summary to expand into component 
      time points which can be displayed, printed, exported, and 
      visualized against a sky view background. Time point data that 
      can be displayed consists of:         
    o Source/Target names         
    o Date of point         
    o Time of point         
    o Target visiblity flag     
    o Range Rate     
    o Source position     
    o Source velocity         
    o Source solar illumination status     
    o Target position         
    o Target velocity         
    o Target solar illumination status

SOLAR BETA ANGLE AND PERCENT SUN

Solar angle and percent sun values may be computed for any satellite 
in the satellite database. This data can be presented for one week, 
month, or year periods, at daily, weekly, or monthly increments. This 
data can be printed or exported.

DATA MANAGEMENT

In addition to the above major tools offered in the SVT, it also has 
built-in site and satellite data management tools which permit simple 
user maintenance of the data. With these tools the user is capable of 
adding, editing, deleting, and importing data elements. Data sets 
managed by the SVT are:

  o Satellite Vehicles
  o Earth Sites
  o Groups 
  o Target Objects

GRAPHICS

The SVT takes advantage of high resolution capabilities of VESA 
compatible video displays (up to 1280x1024) to provide stunning 
visual presentations. With any available mode The SVT is capable of 
displaying: 

  o Positions of any object. 
  o 3D representation of sensor coverage for sites or satellites. 
  o 3D visualization of orbit shapes of single or multiple satellites.  
    Visualize the relationships of satellites within a constellation. 
    Visualization can also be done while editing orbital elements to 
    see effects of parameter changes. 
  o 3D visualization of PROPAGATED orbit shapes of any of the 
    satellites.  Visualization can be made of up to 9 orbits 
    propagated up to 999999 revolutions past the epoch revolution. 
  o Lines of sight from source objects to target objects. 
  o Altitude lines for all satellites. 
  o Visibility footprints for all active satellites in 2D or 3D.

    colors for points illuminated by the sun) 
  o Sub-satellite point position (with or without trail, and 
    different colors for points visible by source)

=====================================================================
The Satellite Prediction Tool Release One
=====================================================================

The Satellite Prediction Tool is a DOS-based application designed to 
provide "compute engine" capabilities for the prediction, and analyis
of earth orbiting objects. With the SPT, you will have the ability to
pre-configure scenarios which can be run from the DOS prompt in an
automated fashion. 

The SPT is automated through a new Macro feature. Macros provide the 
capability of automating the operation of the SPT. Macros are 
"recorded" keystrokes that are contained in a collection and used to 
simulate the user typing keys on the computer keyboard. These 
recorded keystrokes do exactly the same things that the original 
keystrokes did. Macros can be saved to and loaded from files. They 
can even be specified on the command line at startup so that certain 
predetermined operations can be performed automatically. Parameter 
files (those files which configure targets, display attributes, data 
formats, scan times, etc.) may also be loaded from the command line, 
providing further automation control.
