What is the primary operational benefit of MEO satellites used in GNSS systems like GPS over GEO satellites?
Answer
They can achieve global geometry including polar zones.
MEO systems, utilizing multiple orbital planes, are able to ensure coverage across the entire globe, including polar regions, which GEO cannot effectively serve.
