One of the difficulties faced by unmanned vehicles operators is to understand the situation of the vehicle in the local where it is and the relationship of the events that occur there with the vehicle and with the mission that is being executed. This may happen due to the type of control station used and the resources available both in the station as in the vehicle. In this context, this paper investigates how the technologies of Virtual Reality, Augmented Reality and Immersive Telepresence, when used simultaneously, are able to increase the situational awareness of unmanned vehicle operator and the navigation efficiency. For this reason, this paper proposes a control and navigation system to unmanned ground vehicle whose main feature is the simultaneous use of resources related to Virtual Reality, Augmented Reality and Immersive Telepresence. Besides the system, as a way to facilitate the evaluation of this system, were implemented also an unmanned ground vehicle simulator and a tool for visualization and analysis the data generated during the use of the simulator. Regarding of the navigation efficiency, this system was evaluated from the data that describe the vehicle behavior. Concerning the situational awareness, this system was evaluated using the SAGAT method. The results obtained indicate that an immersive instrument is useful when the tasks executed by the vehicle depend on the detailed observation of the local where the vehicle is. However, tasks associated with the pure and simple navigation can be executed with good performance even without the immersive instrument.
