“…Furthermore, these frames are divided into four different one-second frames. In a one-second frame or "subframe," the data is encrypted into 64, 128, 256, and 512 "words" of 12 bits each using the generation of FDR technology described above [37] [38]. An example is shown in Figure 2, obtained from a document from the European Union Aviation Safety Agency (EASA) which shows that the main element of the record is a "word" consisting of 12 bits.…”

“…At Georgia Institute of Technology, a small Navigation, Guidance, and Control (NGC) system was developed using Field Programmable Gate Array (FPGA) and Digital Signal Processor (DSP) technologies for advanced UAV behavior [24,25]. Moreover, some other different institutes developed their own UAVs due to their impact on the growth picture of the scientific R&D roadmap [26][27][28].…”

Over the last decades, Unmanned Aerial Systems (UASs) have gained much attention due to their various applications in different sections. However, their communication range is limited to utilized communication equipment. Therefore, utilization of GSM channels opens a new prospect towards long distance UAV missions and mobile command and control centers. This paper demonstrates new design and development of a small-scale UAV and a Ground Control Station (GCS) using GSM bidirectional communications for Non-Line of Sight (NLoS) long range control. GCSs are considered the front end node in UAV guidance process. Therefore, the proposed GCS employs a two-layer framework to consider all ground pilot requirements. Moreover, a new exploitation of global weather forecast data is added to the GCS. On the other hand, the proposed airborne system utilizes a new integration of different Commercial off-the-Shelf (COTS) components and excludes short range receivers. The ground and flight tests show that stable bidirectional GSM communication is established, reliable hardware integration is accomplished, real time performance is achieved, GCS functional fidelity is obtained, and low cost is maintained. Finally, some qualitative aspects of the proposed platform are presented to address the detailed features.Recently, Unmanned Aerial Vehicles (UAVs) have a great potential in Research and Development (R&D) sections, due to their vital role in academic, industrial, and military applications [1]. Their applications domains cover search and rescue, reconnaissance, intelligent traffic monitoring, border patrol, disaster monitoring, and fire detection (just to name a few) [2]. Small-scale UAV copters, such as quadcopters and helicopters, have attracted many researchers for their unique characteristics. Quadcopters have Vertical Takeoff and Landing (VTOL) capability and perform different flight missions ranging from hovering to cruising with quite good agility and maneuverability. It is considered an ideal platform for nonlinear control law research and a good test bench for trajectory planning algorithms for both remotely piloted and autonomous missions. Designing and implementing a smallscale UAV quadcopter is considered a challenging job [3], due to its role in reducing the gap between the theoretical studies and practical engineering methodologies. During the implementation, researchers might get stuck with many difficulties such as UAV platform specification, airborne systems, communication links, Ground Control Station (GCS) software capabilities [4], and the multiplexed data logging of different inputs and outputs for the Unmanned Aerial System (UAS). Owing to the advent of Microelectromechanical System (MEMS) technology, the airborne systems are shrinking in size and weight. Moreover, using the Commercial offthe-Shelf (COTS) components, it is possible to develop airborne avionics system for a small-scale UAV quadcopter Hindawi Publishing Corporation rectional GSM communication for both uplink and downlink with latency less than 30...

“…Calibration and generation of virtual images with the multi-camera system mounted on the UAV can also be difficult due to the low stability of this type of platform. Wind gusts or heavy load of UAV and a relatively low flight altitude can effectively cause the whole platform to vibrate [ 28 , 29 ]. Therefore, one of the solutions to this problem is the use of the UAV platform presented in this article along with a dedicated 2-axis stabilized head.…”

In the last few years, it has been possible to observe a considerable increase in the use of unmanned aerial vehicles (UAV) equipped with compact digital cameras for environment mapping. The next stage in the development of photogrammetry from low altitudes was the development of the imagery data from UAV oblique images. Imagery data was obtained from side-facing directions. As in professional photogrammetric systems, it is possible to record footprints of tree crowns and other forms of the natural environment. The use of a multi-camera system will significantly reduce one of the main UAV photogrammetry limitations (especially in the case of multirotor UAV) which is a reduction of the ground coverage area, while increasing the number of images, increasing the number of flight lines, and reducing the surface imaged during one flight. The approach proposed in this paper is based on using several head cameras to enhance the imaging geometry during one flight of UAV for mapping. As part of the research work, a multi-camera system consisting of several cameras was designed to increase the total Field of View (FOV). Thanks to this, it will be possible to increase the ground coverage area and to acquire image data effectively. The acquired images will be mosaicked in order to limit the total number of images for the mapped area. As part of the research, a set of cameras was calibrated to determine the interior orientation parameters (IOPs). Next, the method of image alignment using the feature image matching algorithms was presented. In the proposed approach, the images are combined in such a way that the final image has a joint centre of projections of component images. The experimental results showed that the proposed solution was reliable and accurate for the mapping purpose. The paper also presents the effectiveness of existing transformation models for images with a large coverage subjected to initial geometric correction due to the influence of distortion.
