Patent ID: 10151587

Abstract:
In a method for determining navigation data, positional angle measurement values are determined using a first navigation device (310). A second navigation device (320) is then initialized using the positional angle measurement values determined by the first navigation device (310). Both navigation devices are supplied with rotational rate and acceleration measurement values from a common sensor unit in order to determine the positional angle measurement values. In the process, the first navigation device (310) produces erroneous measurements of the positional angle measurement values with a probability which is lower than as specified positional angle error rate, and the second navigation device (320) produces erroneous measurements of the positional angle measurement values with a probability which is higher than the specified positional angle error rate. An erroneous measurement of the positional angle measurement values is present if one of the determined positional angle measurement values deviates from a corresponding positional angle reference value by more than a specified positional angle tolerance value.
