Abstract
Navigation and location services are critical to national security, economic development and social livelihood, and play a pivotal and indispensable role in the new generation of information technology strategic emerging industries. Global Navigation Satellite System (GNSS) cannot provide reliable positioning and navigation services for indoor environments because the signals are blocked by buildings. Pseudolites can overcome the shortcomings of GNSS. By simulating similar navigation signals in an indoor environment and using commercial receivers to achieve seamless indoor and outdoor positioning, it has gradually become a research hotspot in the field of indoor positioning. This article systematically discusses the basic framework, signal system design, positioning algorithm and application of several typical scenarios of pseudolite indoor positioning system, and summarizes the advantages and disadvantages of pseudolite indoor positioning and the future development direction.
