## 5 Task Guidance and Location Monitoring  
Situational awareness on the battlefield can be obtained by utilizing the mCOP application to assess elements of tactical situations in real time. This also considers topographical information that is similar to the exact location (terrain and azimuth) of the given location or object (Figure 8). Such a feature can be especially useful for reconnaissance units to know where they are and where Blueland and Redland forces are. The capabilities described provide for mCOP activity with an AR view (Figures 3, 5 and 8). The main computations of data derived from a device's sensors are made through a route trace component. This component is strictly associated with the activity mentioned above. The arrow that indicates the direction and azimuth of a given point in the terrain is painted on the screen of the device through an OpenGL ES component, which is also responsible for calculating the rotation of this arrow. These calculations are based on data obtained from the device's position as well as motion sensors (mainly magnetometer and accelerometers). The combined components deliver functionality for route management and guidance. In a real scenario, the user-soldier determines the required (preferred) checkpoints on the map as characteristic mission points. The coordinates are input data for an algorithm that determines the azimuth arrow's direction, which is additionally corrected by the tilt of the handheld. In addition, the component (android activity) contains a map overview, which indicates the exact location of the soldier, and compass data merged with the map view. Such a functionality composition delivers simplified actions for the recon soldiers to track their route and determine mission-related objects. The route tracking and topographical orientation can be easily accessed in TARV, which also fuses tactical data and is able to modify the route and characteristic points accordingly to recognize enemy threats, increasing situational awareness but most \begin{table}
