Abstract

Method for operating a vehicle navigation system, wherein: a) vehicles of a vehicle fleet are divided into vehicle groups (112, 114) according to an antenna characteristic related to a terrestrial radio network (106); b) the vehicles (104, 108, 110) of the vehicle fleet determine the position of the measurement location and the signal strength and / or signal quality of the radio network (106) at various measurement locations; c) the vehicles (104, 108, 110) of the vehicle fleet generate signal data for each of the measurement locations, corresponding to the position of the measurement location, the vehicle group (112, 114) of the transmitting vehicle, and the signal strength and / or signal quality of the radio network (106) at the measurement location, and transmit the signal data to a backend (116); d) the backend (116) processes the signal data to generate a to generate a network coverage map that is specific to the antenna characteristics of the respective vehicle group (112, 114);unde) a navigation system (102) of at least one of the vehicles (104, 108, 110) of the vehicle fleet performs a navigation function based on the network coverage map assigned to the vehicle group (112, 114) of the at least one vehicle (104).
