Satellite-to-Indoor Broadband Channel Measurements at 1.51 GHz

Thomas Jost and Wei Wang

Abstract:	Nowadays GPS is broadly applied for outdoor localisation. In indoor environments, reception of satellite signals becomes possible but still position errors caused by signal blocking, diffraction or multipath impede accurate localisation. For a later mitigation of position errors due to the propagation medium, the German Aerospace Center investigated into the satellite-to-indoor wave propagation channel for navigation applications by conducting a broadband channel sounder measurement campaign using a mobile crane as transmitter platform with the receiver being placed indoors. Using this setup, measurements were performed within L-band at 1.51 GHz using a broadband signal of 100 MHz bandwidth. Results are given in terms of power delay profile, root-mean-square delay spread and mean delay. A first coarse analysis of the impacts on a navigation receiver caused by the satellite-to-indoor wave propagation channel is given.
