Sažetak
The growing availability of low-cost positioning
technologies enables broader access to advanced Positioning,
Navigation, and Timing (PNT) services for regional and global
applications. Building on our previous work, which introduced
a Low Earth Orbit (LEO)–PNT optimization framework for
Africa, we extend this framework to the European and Arctic
region and demonstrate that well-designed regional constellations
with only 65-85 satellites can match the performance of
much larger LEO-PNT systems, such as those comprising 240-
282 satellites. We evaluate both regional and global LEO-PNT
performance in outdoor and indoor environments for several
constellations: three newly designed configurations optimized for
European coverage, a previously optimized African constellation,
and seven benchmark constellations.
