Development analysis of PNT-on-a-chip and Comprehensive PNT network management

For the construction of the Comprehensive PNT of ubiquitous navigation and location service, countries are exploring various kinds of navigation and positioning methods to supplement and enrich GNSS. PNT-on-a-Chip is an important direction. By analyzing the development trend of technology and application in the era of Internet-of-Things, this paper puts forward the concept of PNT-on-a-Chip, and analyzes that as an important means to realize ubiquitous space-time service, it will improve rapidly in function and integration with the continuous development of large-scale integrated circuit, and has the largest number and market demand due to its natural good integration ability with IOT chips. The development of Comprehensive PNT network management system assists the integration of PNT-on-a-chip to achieve high performance. In future, R＆D should be intensified in Integration of MEMS and high precision INS, support from Comprehensive PNT network management, and integration of multiple signals on-a-Chip, so as to realize market supply soon.
