This SuperStars award winner from the AGI UC 2005 was submitted by George Krasovec of Data Fusion Corporation. The McMillanRT scenario demonstrates an essential operational capability to view ground coverage patterns for multiple ground, air, or space platforms in real time. It was discovered that by suppressing all natural light sources in the STK 3-D window and associating cominbations of the three primary light colors with the subject platforms, additive color mixing effects can be projected over 3-D terrain that render well-defined ground coverage contours in real time. When using this coloring mixing technique in conjunction with gray-scale chunk imagery, distortion of the mixed color effects is avoided, so that colorshaded contours indicating single, double, or triple ground coverage are readily apparent in 3-D.

In addition to dynamic coverage contours, this scenario shows other ways that dynamic data are brought into STK to augment GIS data. There is a ground vehicle navigating the San Fran streets, and STK show the access lines to the visible GPS satellites. The scenario also shows the aircraft locations during their flights. Stored views include the ones above, plus one view for each of the four aircraft flight paths, one view of the San Francisco roads, and one from the point of view of the car driving along the roads.

This scenario enables an analyst to determine the portions of selected regions that will be observed from a space-based down-looking camera throughout a period of a week. The selected regions are three large watersheds in the United States of America: The Mid-Atlantic region, the Lower Mississippi region, and the Upper Colorado region. The camera is modeled as a 5 degree field-of-view sensor mounted on a low-Earth satellite following a repeating ground-track orbit.

An SUV is driving from Baghdad to Damascus and there is an 800 mW mobile phone in use. Surveillance aircraft and communications monitoring aircraft are performing routine missions. STK/Coverage and Communications modules are used to analyze when, how long, and to what quality the signal from the mobile phone could get intercepted - dynamically as the SUV is moving.

Globeserver is also demonstrated with the inclusion of terrain and imagery into the analysis.
A ground vehicle target of interest is driving on a roadway in a border patrol sector near the Arizona-Mexican border. A Hunter UAV is operating within the area and is monitoring the movement of the target vehicle. While the monitoring station is not in view of the UAV, a LEO communications satellite is used to reroute the data.

The globe in this VDF uses the Planet Earth world texture with the night lights and specular overlays. To see the dynamic lighting effect first use the magnifying glass button to fix your view on the US and then use the slider animation tool to dynamically change the time of day and observe the changes to the globe lighting (specular, to not specular, to night lights). The scenario also includes 5 overlays and stored views to each: 1) Mt. St. Helens (B&W with terrain), 2) Northern Cal topographic imagery (false color, no terrain), 3) Crater Lake (B&W with terrain), 4) Kauai (imagery and terrain), and 5) Afghanistan topographic (false color, no terrain).

The Chesapeake Bay Underwater Scenario is a Homeland Security or Port Security STK scenario example. An enemy submarine and frigate are in the Chesapeake Bay area and causing an elevated alert status due to a commercial ship spotting. The military scrambled an aircraft to fly in a racetrack path over the last known location. Once at sea the aircraft was given orders to drop sonar buoys along the flight path. After the buoys were dropped friendly assets where reassigned to assist in the neutralizing of the concern if detected.

This scenario demonstrates STK's ability to compute
navigation accuracy for GNSS operations. An F-18 is
on a training mission in the Northeastern U.S. GDOP
coverage is being computed for CONUS in order to
show regional dynamic navigation accuracy for the
GPS constellation during the mission. In turn. the
static positional accuracy is computed for the F-18
while it flies its mission, including a period where the
aircraft's route drops to 500 ft. and follows the terrain
in a mountainous region, thus effecting its access to
GPS satellites. This degradation can also be seen on
the quick report for PDOP included with the VDF. The
static converage for the F-18 is using the Best 4 GPS
satellites in view, while the regional GDOP calculations
are over determined.
