Low Earth orbit (LEO) constellations offer a new avenue for assuring PNT. With satellites closer to the Earth, they provide stronger signals and improved positioning accuracy with rapidly changing geometry. They complement GNSS resiliency, security and precision for PNT, making LEO an attractive alternative PNT option for the industry to pursue.
