UNMANNED AIRCRAFT SYSTEMS
Small scale unmanned aerial vehicles (UAVs) have become more commonly used for many applications. The need for aircraft with greater maneuverability and hovering ability has also led to the current rise of quadcopters. The term unmanned aircraft system (UAS) emphasizes the importance of other elements beyond an aircraft itself. A typical UAS consists of: unmanned aircraft (UA); control system, such as Ground Control Station (GCS); control link, a specialized datalink; and other related support equipment.
The maritime counterpart of unmanned air system are the unmanned maritime systems (UMS). UMS include underwater vehicles as well as surface vehicles. Unmanned underwater vehicles (UUV) have a larger complexity due to the difficulty that underwater communications imply.
We can design, develop and implement low cost, mission specific unmanned systems; to support the acquisition process of hardware, systems, sub-systems and components; and support research activities on control, navigation, guidance, embedded systems, systems engineering, propulsion, power systems, modeling, simulation, harware-on-the-loop, and others.
A quadcopter, also called a quadrotor helicopter, quadrotor, is a multirotor helicopter that is lifted and propelled by four rotors. Quadcopters are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by a set of rotors (vertically oriented propellers). They are a great option when precision flight is required.
Fixed-wing aircraft tend to be more forgiving in the air in the face of both piloting and technical errors, as they have natural gliding capabilities with no power. Fixed-wing aircraft also are able to carry greater payloads for longer distances on less power.
Naval unmanned surface vehicles (USV) and unmanned underwater vehicles (UUV).
An unmanned planetary exploration aircraft is a vehicle for flying in the atmosphere of planets others than Earth (i.e. Mars). So far, lander entry, descent, and landing systems have passed through the atmosphere, umanned aircrafts may provide in situ measurements of the atmosphere of the planet, as well as additional observations over extended areas.
