摘要：In a method for optimizing the accuracy of position determination, and/or for
reducing the integrity risk, of a receiver in a global satellite navigation system having aplurality of satellites, for at least one satellite that is visible to the receiver (E), a deviationerror (AF) is determined which is a function of the geometric orientation of the satelliterelative to the receiver, and of at least one system parameter. The deviation error isdetermined based on an additional deviation error generated by an error projection intoa coordinate system of the receiver. A first or a second value, whichever is smaller of thetwo, is used as the deviation error. The first value for the at least one system parameteris determined using a respective specified parameter value. The second value isdetermined for the at least one system parameter, using a modified parameter valuewhich is modified with respect to the specified parameter value in such a way that a lowererror in the modified parameter value of the at least one system parameter is acceptedas true.
