The aim of this thesis is to show that Global Navigation Satellite Systems (GNSS) positioningcan play a significant role in future automotive applications. Which can be achieved by usingstate-of-the-art GNSS positioning technology and by exploring more the rapidly developingconcepts of high-precision correction services. The combination of the state or the arttechnology and correction services will enable higher performance in terms of precision andaccuracy in positioning than can be achieved today. In this thesis, benchmarking a highprecision GNSS system with latest correction services is focused and the feasibility of deployingthese technologies in the real automotive environment.Global Navigation Satellite System (GNSS) has become very important to the modern world,and we generically see this with different versions of it found in nomadic devices, dedicatedGPS navigation devices, and built-in vehicle navigation. These systems use a positioning GNSSchipset, which allows position information to be obtained from satellite anywhere in the worldwith an accuracy of about 2-10 meters, depending on the performance of the chipset.However, there are few limitations in terms of accuracy, and sometimes they provideincorrect navigation but generically they are quite stable, and further improvements have beenmade with the integration of motion sensors and map matching algorithms to solve deadreckoning problems and improve positioning accuracy.However, with the development of advanced automotive applications that require a high-performance positioning system, these systems have become obsolete. Due to the strictrequirements of such applications, including high positioning accuracy (in the centimeterrange), high solution availability and continuity (100%), and high position data integrity.Traditional low-cost GNSS receivers generally do not meet these requirements. There is agrowing need for positioning solutions in the automotive industry to meet Advanced Driver-Assistance Systems (ADAS) in autonomous vehicles. GNSS-based vehicles require lane-levelresolution to navigate safely and reliably.This paper investigates and compares the high precision GNSS system and what is required toachieve the same using different correction service methods. We have seen there are severalintroductions of Virtual Reference Stations (VRS) across the world, which uses Network RealTime Kinematic (N-RTK) principle and thus absolute vehicle positioning is made possible byable to exchange information between vehicles to VRS. Thesis has also investigated the pseudo-VRS which improves the positioning performance of high-precision vehicle GNSS systemsthrough the increased availability of GNSS correction messages and through the fast resolutionof the N-RTK solution. 4It is shown that SSR a global N-RTK positioning is one such technique. N-RTK can provideabsolute positioning solutions with centimeter level accuracy and high availability, continuityand integrity. A key component of N-RTK is the availability of real-time GNSS correction datadelivered to the GNSS receiver via the mobile Internet (for a mobile receiver) or a telematicsunit.
