To keep GPS constellations from drifting, look to the moon
Global positioning systems are essential for everyday life, guiding everything from maritime shipping to daily commutes. Maintaining the extreme accuracy of these satellite constellations requires constant adjustments and innovative solutions. Recent scientific discussions propose using the moon as a stable reference point to prevent GPS constellations from drifting over time. This celestial approach could significantly enhance navigation reliability and reduce reliance on ground-based corrections.
