| description | Due to the strong dependency of our societies onGlobal Navigation Satellite
Systems and their vulnerability to outages, there is an urgent need for
additional navigation systems. A possible approach for such an additional
system uses the communication signals of the emerging LEO satellite
mega-constellations as signals of opportunity. The Doppler shift of those
signals is leveraged to calculate positioning, navigation and timing
information. Therefore the signals have to be detected and the frequency has to
be estimated. In this paper, we present the results of Starlink signal
measurements. The results are used to develope a novel correlation-based
detection algorithm for Starlink burst signals. The carrier frequency of the
detected bursts is measured and the attainable positioning accuracy is
estimated. It is shown, that the presented algorithms are applicable for a
navigation solution in an operationally relevant setup using an omnidirectional
antenna. |
