Abstract: Low Earth Orbit (LEO) satellites, with their unique advantages in constellation and signal, are gradually gaining attention and favor in the world's satellite navigation field, and are expected to become a new increment in the development of the new generation of satellite navigation systems.With the low orbit constellations represented by the Starlink program in the United States becoming a new battlefield for global competition for space strategic resources, the development direction of satellite navigation enhancement is also gradually tilting towards the low orbit field, becoming a new growth and empowerment point for the next generation of satellite navigation.This article first introduces two major types of low orbit navigation enhancement technologies, namely information enhancement and signal enhancement; Summarized the current development status of global low orbit satellite navigation; Explained the key technologies for enhancing low orbit navigation; The focus was on discussing the new development opportunities brought by low orbit navigation enhancement technology for building a Global Navigation Satellite Systems (GNSS) global space-based monitoring network, providing global quasi real time high-precision services, and providing global high integrity monitoring services; Finally, the inspiration and suggestions for the development path of low orbit navigation enhancement technology were summarized.
