UNMANNED AIRCRAFT SYSTEM (UAS) and CIVIL APPLICATIONS (HAPS)
The future UAS market in the civil and commercial fields will come substituting the manned aircraft, which currently perform those missions in the respective fields. Nonetheless, there are other areas where UAS will not merely replace manned aircraft but potentially will be able to provide a capability previously unexistent. An each time higher population brings as a consequence an ever-increasing number of potential civil UAS users emerging with varied requirements for civil UAS applications. The origin of UAS-based wireless systems comes principally from the military research. In the last years, a new set of options have been added in the form of UAS mostly operating at stratospheric altitudes or other lower altitudes.
An unmanned aerial system (UAS) is either treated as a very low satellite or a very tall mast. For example, the HAPS is a vehicle holding a fixed position in the Earth’s atmosphere. It is presumed located at altitudes from 17 to 50 K m, and must offer an ideal platform supporting radio communications and other services. Another aeronautical platforms as balloons or UAVs have another altitudes or can facilitate other civil services complementary to radio communication services.
Nowadays, UAS are based on lighter-than-air (LTA) airships, vehicles, or conventional aircrafts, and are at various stages of research and possible implementation. Another development at a glance is the provision military research with the so-called Unmanned Air Vehicles (UAVs), being in parallel with the logistics of civilian communications from high altitude platform systems (HAPS).For instance, HAPS have many similarities and differences with satellite systems, but mainly represent an economically attractive way for provisioning time-space coverage communications.Another aspect to consider is related with topics in the field of data-link communication and telemetry and command (TT and TC) Civil UAS and HAPS and Robust systems.
The portfolios of activities that are carried out in this field are related with:
*Spectrum requirements for UAS radio communications
*Data-link communications
*UAS(aeronautical/balloons platforms) Radio Frequency technologies in DL, Payloads, S&A, ATC, ...
*Analysis of Characteristics of UAS and spectrum requirements to support their safe and secure operations in non-segregated airspace
*Physical Layer Issues of Advanced Radio communications Systems
*Channel modeling for UAS (HAPS) radio communications
*Propagation Mitigation Techniques for UAS radio communications
*Perform simulations and the theoretical performance analysis to confirm simulation results in these areas.
