“…UAV and related technologies are developing quickly with more and more efficiency and currently, the main limitation of UAV multirotor is energy (batteries). However, as the following papers show [57,58], these problems are being addressed by several research groups. Our research does not depend on the crop field size.…”

This article describes the technical specifications and configuration of a multirotor unmanned aerial vehicle (UAV) to acquire remote images using a six-band multispectral sensor. Several flight missions were programmed as follows: three flight altitudes (60, 80 and 100 m), two flight modes (stop and cruising modes) and two ground control point (GCP) settings were considered to analyze the influence of these parameters on the spatial resolution and spectral discrimination of multispectral orthomosaicked images obtained using Pix4Dmapper. Moreover, it is also necessary to consider the area to be covered or the flight duration according to any flight mission programmed. The effect of the combination of all these parameters on the spatial resolution and spectral discrimination of the orthomosaicks is presented. Spectral discrimination has been evaluated for a specific agronomical purpose: to use the UAV remote images for the detection of bare soil and vegetation (crop and weeds) for in-season site-specific weed management. These results show that a balance between spatial resolution and spectral discrimination is needed to optimize the mission planning and image processing to achieve OPEN ACCESS Remote Sens. 2015, 7 12794 every agronomic objective. In this way, users do not have to sacrifice flying at low altitudes to cover the whole area of interest completely.

“…However, the outcome, performance and basic mission functions gained by active research have a limited effect by the short flight time of existing multicopters [5,6]. As shown above, research is also actively being carried out to improve the flying time which is pointed out as the biggest disadvantage of multicopter.…”

In this paper, We propose a hybrid multicopter that combines an gasoline propulsion system and an electric propulsion system to improve the endurance of the multicopter. The hybrid is equipped with a coaxial inverting thruster using a gasoline engine at the center and an electric propulsion system for attitude control at the side. The control system using a classical control algorithm based on the dynamic model. Finally, flight performance and high-endurance flight of the hybrid multicopter were verified.

Multicopters are the most popular rotary type of unmanned aerial vehicles. They are a type of helicopter with three or more, usually fixed-pitch, propellers that lift and control the platform by individually changing their rotational velocities. The main advantages of a multicopter are its compactness, robustness, and low cost to build and repair. However, currently no published research determines objectively, quantitatively, and experimentally, the maneuverability and agility of multicopters. Numerous maneuverability and agility metrics, together with detailed test procedures and minimum requirements, exist for manned aircraft. Nevertheless, some of these are not directly applicable to small-size unmanned aircraft. A new test procedure, derived from manned aircraft industry practices and research, based on a simple openloop step input maneuver, was developed. It experimentally determines nine maneuverability and agility metrics using only onboard flight controller logs. The test procedure is validated using two different multicopters.
