Abstract
A device, system and method for an update system for updating a digital map for a vehicle. The update data is sent from a control center via a satellite navigation system to the individual receivers. The update data is received by the receivers in parallel with the position data from the satellites. For this purpose, a subchannel is provided. This allows large portions of the worldwide population to be supplied with the update data.
