Low Altitude Pseudo Satellites and Platforms based on LTA-UAVs

This paper explores the development and evaluation of Low Altitude Pseudo Satellites (LAPS) using Lighter-Than-Air Unmanned Aerial Vehicles (LTA-UAVs), focusing on their application in Beyond Visual Line of Sight (BVLOS) operations. The study describes the prototype design of LTA-UAVs, emphasizing aerodynamic efficiency, autonomous navigation capabilities, and payload optimization. Experimental investigations assess the platforms´ structural robustness, bidirectional communication capabilities, and global range controllability under varied atmospheric conditions. The research highlights the integration of advanced multiprocessing algorithms for autonomous BVLOS operations and the implementation of redundant communication systems, including satellite networks. Results demonstrate the viability of LAPS as a cost-effective, scalable solution for lower altitude applications, complementing conventional satellite systems. The findings indicate significant potential for LAPS in earth observation, connectivity enhancement, and integration with Internet of Things (IoT) frameworks. This research contributes to the aerospace field by detailing innovative applications of LTA-UAVs and enhancing the efficiency and global operability of airborne platforms for BVLOS missions.
