ENHANCED SITUATIONAL AWARENESS AND TARGETING (eSAT) SYSTEM
First Claim
1. A method of providing enhanced situational awareness to a host operator and one or more forward positioned mobile operators, comprising:
- providing a host computer with a three-dimensional (3D) model rendered from images of a scene, said 3D model capable of geometric manipulation from different viewpoints;
displaying a visual representation of the 3D model from a specified viewpoint on a host computer display, said host computer configured to allow host operator manipulation of the 3D model to change the viewpoint;
dynamically capturing a first windowed portion of the visual representation of the 3D model at a given refresh rate; and
streaming the first windowed portion of the visual representation over a wireless network to the handheld devices of one or more mobile operators forward positioned in the vicinity of the scene, said handheld devices configured to allow mobile operator selection to stream the first windowed portion of the visual representation to a handheld device display.

Abstract
eSAT pushes 3D scene awareness and targeting to forward positioned mobile operators and their handheld devices in environments such as found in military theaters of operation, border control and enforcement, police operations, search & rescue and large commercial industrial operations. A host computer hosts a 3D model of a scene and dynamically captures and transmits a windowed portion of the visual representation of that 3D model over a wireless network to the mobile operators'"'"' handheld devices. The windowed portion of the visual representation is streamed directly to the operators'"'"' handheld device displays. The mobile operators may interact with and control the 3D model via the wireless network. The host computer may synthesize the visual representation of the 3D model with live feeds from one or more of the handheld devices or other assets to improve situational awareness. Either the mobile operators or host operator can make point selections on the visual representation to extract geo-coordinates from the 3D model as a set of target coordinates.
