The results of considerations regarding the system architecture and the final design of the mobile measurement station are described.1. INTRODUCTION
This article describes the results of research conducted as part of a scientific project, the scientific goal of which was to develop an autonomous method for monitoring GNSS reliability in urban agglomerations. This method would ensure an appropriate level of protection against gross positioning errors, thereby enabling the use of satellite positioning in public safety systems. As is well known, tall buildings in cities cause radio shadowing and signal reflection effects, which on one hand lead to large coordinate determination errors, and on the other, prevent the use of receiver-level navigation solution assessment methods, i.e., RAIM (Receiver Autonomous Integrity Monitoring), designed for aviation. The essence of the addressed problem was to investigate the possibility of using digital image analysis of the environment surrounding a moving object to verify the correctness of coordinate determinations using GNSS in urbanized areas.
