    Noise performance of the modernized GPS and GALILEO systems
    (2010) Gerst, Sebastian
    With the modernization of GPS and the development of the new European satellite system Galileo, the noise performance of the newly introduced signals is understood insufficiently. Today, these new signals are not used operationally, but they are implemented in two satellites in the case of GPS and two Galileo test satellites. Both systems are emitting the new and conventional signals, which are recorded by a Septentrio receiver. The main goal of this thesis is to split the portion from the received signal, which is dependent on the temporal trend. On the one hand the satellite-receiver geometry, on the other hand the ionospherical runtime error. The resulting signal can be interpreted as noise, of which the correlation behavior and the power spectrum should be discussed.
