Problems solved by technology

[0006] However, the above existing technologies still have the problems of high dependence on fixed reference stations and too small service area coverage, and cannot effectively avoid the "urban canyon" and "multipath" effects

Abstract

The invention provides a system for cloud-based generation and distribution of GNSS signal correction data. The system comprises at least one first vehicle, a second vehicle and a rear-end server. Thefirst vehicle transmits the obtained accurate position and the GNSS signal observation value to the rear-end server. The rear-end server calculates the GNSS signal correction data based on the received data and transmits the correction data to the second vehicle. The second vehicle calculates its own accurate position based on the received GNSS signal correction data and the GNSS signal observation value. The rear-end server can also receive reference GNSS signal correction data of the DGPS reference station for verification. The invention also provides a method for generation and distribution of the GNSS signal correction data. The system and method described above can enhance or supplement the performance of the DGPS system.

Description

technical field [0001] The present disclosure relates to navigation systems and methods, and more particularly to systems and methods for generating and distributing Global Navigation Satellite System (GNSS) signal correction data. Background technique [0002] Global Navigation Satellite System (GNSS) can provide location and time information to devices anywhere on the earth. In recent years, the rapid development of vehicles with autonomous driving functions has led to a sharp increase in the demand for vehicles using GNSS signal positioning. [0003] For the positioning error of the GNSS signal, the Differential Global Positioning System (DGPS) is usually used for correction. An existing DGPS system for correcting GNSS signals includes user equipment (such as a vehicle with a GPS receiving unit), GPS satellites, and a DGPS correction data reference station (referred to as a reference station). The verified reference station will compare the GNSS signal observation value...
