Recently, there is a need to acquire intelligence in hos- tile or dangerous environments such as caves, forests, or urban areas. Rather than risking human life, back- packable, bird-sized aircraft, equipped with a wireless camera, can be rapidly deployed to gather reconnais- sance in such environments. However, they first must be designed to fly in tight, cluttered terrain. This pa- per discusses an additional flight modality for a fixed- wing aircraft, enabling it to supplement existing en- durance superiority with hovering capabilities. An in- ertial measurement sensor and an onboard processing and control unit, used to achieve autonomous hover- ing, are also described. This is, to the best of our knowledge, the first documented success of hovering a fixed-wing Micro Air Vehicle autonomously.
