Accuracy and the use of GNSS sensors in a mobile navigation system for inland shipping
Abstract
Characteristic issue in mobile systems is dynamic presentation of information, depending on the continuously changing observer's position (a boat in case of MOBINAV). Thus, the key issue is to consider the own ship position in the system. Usually it is obtained from satellite systems with commonly used GNSS receivers built in mobile devices.
Proposing MOBINAV, the original, mobile navigation system for inland shipping, the authors attempted to verify the accuracy of GNSS sensors built in selected mobile devices. Two testing scenarios have been proposed. The first one has assumed the comparison of the HDOP index and the number of traced satellites during the passenger car test. In the second scenario the GNSS data from mobile devices has been compared to reference data.
