High-altitude platform stations (HAPS) have gained significant attention for their role in supporting intelligent transportation systems (ITS) due to their wide coverage and cost-effectiveness. Positioned at 20 km altitude, HAPS serve as aerial base stations, where terrestrial networks are unavailable or damaged due to disasters. However, wind disturbances can cause HAPS to drift, leading to coverage hole area and reduced reliability in ITS operations. To address this challenge, we propose the use of networked flying platforms (NFPs), specifically unmanned aerial vehicles (UAVs) as a backup system to dynamically restore coverage and ensure continuity and stability in ITS services during HAPS displacement. The study uses the ERA5 wind dataset for the year 2023 to analyze stratospheric wind behavior in Doha, Ottawa, and New York, confirming the global need for backup solutions during high-wind events.
