A New Ground-based High-precision Local Positioning System for Indoor and Outdoor Positioning

The Ground-based High-precision Local Positioning System (GH-LPS) proposed in this paper is used as a supplement, backup and enhancement of the satellite positioning system. Its main feature is that it can work with the space-based system, and overcome the shortcomings of satellite navigation system in terms of accuracy, reliability, availability and anti-interference in the condition that satellite navigation system is interfered, blocked or unusable. The system can independently provide, high-reliability, low-cost, centimeter-level positioning and navigation means in the area where the spatial signal is missing, and solve the last one-kilometer problem of high-precision positioning and navigation services.
