abstract = "This paper shows the autonomous UAVs (Unmanned Aerial Vehicle)
project and development to be applied in remote sensing using a
specialized lightweight multispectral camera. The vehicle performs
the flight, takeoff and landing procedures in total autonomous
mode without need a human pilots remote assistance during the
entire mission time. The algorithms for autonomous missions were
developed in ROS (Robotic Operation System) framework, which is a
well-established workstation environment for development in
robotics platforms. A friendly graphical pre-mission interface was
developed for an easy interaction with the operator depicting the
geographical map of the desired area. The bioinspired optical flow
technique was applied for merging the GPS data and the optical
vector data for an enhancement of the aircraft position
estimation, overcoming the position error of a single GPS module
operation. The performance improvement in position estimation was
58% better than the single GPS module and improves the autonomous
navigation procedures. Moreover, a novel optical fiber sensor,
immune to electromagnetic interference, was developed to measure
the electrical current that feeds the electrical engines. After
that, the multispectral camera was embedded into the aircraft to
perform the NDVI (Normalized Difference Vegetation Index)
calculation in previous target areas, which can be correlated with
healthy vegetation areas.",
