LEO Navigation Augmentation

LEO navigation augmentation is a technology that uses navigation signal transmitters aboard low Earth orbit (LEO) satellites to enhance the positioning accuracy, signal strength, and convergence speed of existing medium Earth orbit GNSS systems such as GPS and BeiDou. Due to the low orbital altitude of LEO satellites (200–2,000 km), the signal path loss is significantly reduced, greatly improving navigation performance in weak-signal environments such as urban canyons and indoor settings. This represents a key development direction for next-generation PNT architectures.
