A Challenge for Micro and Mini UAV: The Sensor Problem
Abstract
There is no doubt that so called tactical or short-range UAV played an important role in the military conflicts of the last 15 years. Such assets are expensive and very demanding regarding maintainability, operability and safety. Consequently they are operated at the levels of the brigade and higher. However, the commanders of the battalion and company, and even the platoon and squad leaders need also local situational awareness. This is the reason why in many countries, also outside NATO, Micro and Mini Aerial Vehicles (MAV), with dimensions not exceeding 15 cm respectively 150 cm, are presently under development. Typical missions are "Looking over the hill" or "Looking over the obstacle" (figure 1). Decreasing the size of such platforms is very challenging in all domains. Besides the platform complexity (aerodynamics at low Reynolds number, small but efficient and safe propulsion systems, high but compact and light weight energy storage devices, pre-programmed and fully automated flight), the sensor part of a MAV is extremely exigent. In addition to mission sensors (EO/IR), MAVs need sensors to navigate, to provide stability and to allow manoeuvrability. This contribution will focus on micro-cameras, navigation sensors and attitude sensors. A large variety of micro-cameras are available off the shelf. During the last five years the UAV centre of the RMA gained a wide experience in this field and results in connection with military equipment are discussed in the paper.
