The networked situational awareness sensor system (SAS) provides small unit leaders and team members with the ability to understand, control, and dominate the battlespace by providing comprehensive situational awareness and reliable connectivity.
SAS consists of scatterable networked sensor units that are designed to detect, report, record, and interpret movements and activities of people and vehicles within the area of sensor deployment. This data may then be accessed with wireless Internet using SAS viewer software.
The SAS system can be applied in a wide variety of applications and CONOPS. SAS can scout and monitor urban and complex terrain without human intervention. Whether hand-placed or air-delivered, the networked SAS system provides persistent surveillance over areas of interest. In an air assault, SAS can distinguish threats from friends and monitor the cleared area after operations; in operations other than war, SAS can function as a remote sentry, monitor crowds or militia movements, and characterize population. SAS can be the cornerstone for a perimeter management system, detecting concealed and covert threats with highly specific motion detection. In maneuvers, both under pressure and unconstrained, the network can serve as route-side monitors wirelessly linked to vehicles, tracking both friendly and threat vehicles.
The SAS system is made up of two basic elements: the graphical user interface and the multinode sensor.
Graphical user interface
The graphical user interface (GUI) wirelessly communicates with the sensor network, downloads data, and provides interpretation for a common operational picture. The GUI will allow easy communication among team members, and provide responses to basic questions such as "Where am I?" "Where are my buddies?" and "Where is the enemy?"
Multinode sensors
The multinode sensor processes detections and identifications locally, using node-to-node collaboration to assess and 
identify threats.
The sensor nodes communicate over a secure radio and embedded wireless network, which enables the sensors to communicate in a self-forming, self-healing wireless mesh network. The network also acts as an embedded router and repeater to extend network range and reliability. The mesh networking automatically adapts to form reliable communication paths, even in the face of radio frequency interference.
