“…Satellite systems are especially important for enabling communications to aircraft in oceanic and other unpopulated areas, since they are capable of providing global coverage, as well as global discovery and control for other communication systems. A2S communication also complements A2G communication where appropriate [72], for example, for locating the position of aircraft. However, apart from having a high cost, aeronautical communication relying on satellites suffers from very long end-to-end propagation delays of approximately 250 ms [43], which prevent its use in latency-sensitive applications, such as formation flight.…”

The engineering vision of relying on the "smart sky" for supporting air traffic and the "Internet above the clouds" for in-flight entertainment has become imperative for the future aircraft industry. Aeronautical ad hoc Networking (AANET) constitutes a compelling concept for providing broadband communications above clouds by extending the coverage of Air-to-Ground (A2G) networks to oceanic and remote airspace via autonomous and self-configured wireless networking amongst commercial passenger airplanes. The AANET concept may be viewed as a new member of the family of Mobile ad hoc Networks (MANETs) in action above the clouds. However, AANETs have more dynamic topologies, larger and more variable geographical network size, stricter security requirements and more hostile transmission conditions. These specific characteristics lead to more grave challenges in aircraft mobility modeling, aeronautical channel modeling and interference mitigation as well as in network scheduling and routing. This paper provides an overview of AANET solutions by characterizing the associated scenarios, requirements and challenges. Explicitly, the research addressing the key techniques of AANETs, such as their mobility models, network scheduling and routing, security and interference are reviewed. Furthermore, we also identify the remaining challenges associated with developing AANETs and present their prospective solutions as well as open issues. The design framework of AANETs and the key technical issues are investigated along with some recent research results. Furthermore, a range of performance metrics optimized in designing AANETs and a number of representative multi-objective optimization algorithms are outlined.

“…In both cases, assuming a ground station antenna height of h GS , reflector positions of constant delay M or Doppler frequency f M can be found by setting d U = -h GS in (1) and (2). The closed form solution used for calculation of presented results can be found by bringing (1) and (2) into the general scalar form of a quadric curve [9] and then solving for y = f (x).…”

In this contribution, we present a method to analyze the effectiveness of multipath mitigation by extended averaging in the context of terrestrial radionavigation. We derive the requirements of extended averaging on the geometry between a ground station and an aircraft. Using that knowledge, we are able to analyze the effectiveness of extended averaging for real‐world flight trajectories. Copyright © 2017 Institute of Navigation.

This survey studies the potential data link candidates for unmanned aircraft vehicles (UAVs). There has been tremendous growth in different applications of UAVs such as lifesaving and rescue missions, commercial use, recreations, etc. Unlike the traditional wireless communications, the data links for these systems do not have any general standardized framework yet to ensure safe co-existence of UAVs with other flying vehicles. This motivated us to provide a comprehensive survey of potential data link technologies available for UAVs. Our goal is to study the current trends and available candidates and carry out a comprehensive comparison among them. The contribution of this survey is to highlight the strength and weakness of the current data link options and their suitability to satisfy the UAVs communication requirements. Satellite links, cellular technologies, Wi-Fi and several similar wireless technologies are studied thoroughly in this paper. We also focus on several available promising standards that can be modified for these data links. Then, we discuss standard-related organizations that are working actively in the area of civilian unmanned systems. Finally, we bring up some future challenges in this area with several potential solutions to motivate further research work. Index Terms-Unmanned aircraft systems (UAS), unmanned aircraft vehicle (UAV), civilian applications, data link, satellite communication, cellular communication, aviation standards, standard bodies, future challenges. SATCOM Provider ATC Pilot Cellular Provider Satellite UAV Cellular Tower Fig. 1 2 2) Network RequirementsThere are several survey papers discussing the requirements for UAS data link such as [2], and [9][10][11][12][13][14]. For example, the requirements for the UASs based on four different areas of missions, communication networks, communication data links, navigation, and surveillance are discussed in [2]. Several detailed discussions about the communication data link requirements such as range, velocity, latency, reliability, availability, integrity, security, and bit rate are provided. As another instance, a survey of UAVs communication requirements has been studied in [9]. These requirements are based on four categories of UAV applications (i.e., search and rescue, area coverage, delivery/transportation, and construction). Moreover, the important requirements and considerations regarding the network layer of UAV communications have been discussed in [14]. 3) Channel ModelingChannel modeling must be studied for designing and evaluating proper UAV data links for different applications. There have been several research work and surveys on channel modeling for UAV communications, such as [15][16][17][18]. For instance, a comprehensive survey on channel modeling for UAV communications is provided in [15]. Different channel modeling approaches along with the associated challenges have been studied. 4) Our ContributionWe have studied the existing survey papers on the aforementioned issues related to the UAV data links.
