The development of the Galileo system will significantly improve the already high level of accuracy, availability, reliability and integrity provided by current satellite navigation systems. However, in urban canyon and indoor locations there's a significant performance loss due to high levels of attenuation, signal masking and multipath.
Receiver design for positioning in challenging areas like this is dependent on accurate characterization of the signal and noise environments. Effects of signal propagation into urban canyons and indoors is relatively well known. However, the noise characteristics are largely unknown, especially the effect on the noise floor, in the sensitive Galileo bands, from the increasing number of electronic devices.
The key objective of the proposed research is to characterize the man-made, unintentional, noise in the Galileo L1 and E5 bands. Two distinct hardware development projects will be initiated. One will provide a high-end measurement device with a spectrum analyzer as the key element. The other project will provide a low-cost instrument that is more suited for parallel deployment.
