The invention relates to a radio navigation device for receiving, evaluating, and processing faulty navigation signals, containing at least one receiving apparatus and at least one evaluating apparatus, wherein the radio navigation device has or is connected to a database, which provides substantially statically stored positioning data of defined, predictable regions or areas, which positioning data can be predetermined, and the database sends error information of the received radio navigation signals to the evaluating apparatus and/or a user terminal in dependence on predefined location information with regard to predictable regions or areas of deficient or lacking radio navigation signal reception. The invention further relates to a method for receiving, evaluating, and processing navigation signals, in particular by using the radio navigation device. |
