摘要

The modernization of existing satellite navigation systems like GPS,GLONASS and the construction of new systems such as Galileo or COMPASS raises the question for interoperability and interference between these navigation systems.The constant growing number of applications based on satellite navigation systems especially safety critical ones like airplane landing or applications on railways require highest precision and robustness of the positioning solution also available under rough conditions. rnIn order to guarantee undisturbed operation with sufficient performance a detailed measurement and analysis of different aspects is necessary.Next to an initial and fundamental verification of the Signals in Space(SIS),an accurate and comprehensive interference measurement of unwanted and possible perturbing emissions and a clear separation of the different sources are necessary since they can degrade the performance and integrity of safety critical applications. rnThis paper gives a short overview of the used facility and the previous work which was necessary for the paper. This includes a short description of the measurement setup and the performed calibrations which describes the gain determination of the 30m antenna and the calibration of the receiving system.In the next step an analysis of the performed ground based interference measurements at the antenna location is given.Finally a detailed overview of the accomplished interference measurements on different GNNS and other L Band satellites is presented and discussed in the end of the paper.
