Development of total energy simulator for high altitude platform station operation

The rise of sustainable communication networks marks a transformative era in connecting our world, and non-terrestrial networks (NTN), especially high-altitude platform stations (HAPS), are at the forefront of this revolution. These innovative systems are not only vital for emergency communications and reaching remote areas, but they also embody our collective commitment to a sustainable and resilient future. Our groundbreaking study introduces an advanced energy simulation algorithm for HAPS, meticulously accounting for environmental factors that influence photovoltaic power generation. By modeling energy consumption across various flight phases, our findings reveal that solar energy production varies with time and location, with westward evening flights demonstrating peak efficiency. A comprehensive three-day simulation near Miyazaki Airport validates the extraordinary potential of HAPS, inspiring confidence in their practical application. Contrary to conventional beliefs that PV outputs remain stable at high altitudes due to minimal cloud cover, our measurements uncovered remarkable fluctuations shaped by curved-shaped behavior. We have successfully modeled this unusual phenomenon using sophisticated tensor-vector computation, paving the way for more reliable and efficient PV system designs. • An energy simulation algorithm was developed for PV-powered HAPS operations. • The model factors in solar irradiance, temperature, and geolocation using 3D meshes. • A 3-day simulation near Miyazaki Airport proved HAPS operationally feasible.
