Method and device for determining estimated error information of a navigation signal

摘要

Method for determining estimated navigation signal error whereby several receivers (RU1-RU4) receive navigation signals from at least one navigation signal transmitter. At least one evaluation unit evaluates the navigation signals and transmits the error information to a user terminal (UT) via a radio navigation system (2). According to the method: the evaluation unit uses a number of error models; dependent on a defined selection standard an error model is selected; and the error signal is determined using it and transmitted. Independent claims are included for (1) a corresponding evaluation unit; and (2) a computer program for determining estimated navigation signal errors
