Summary, etc | "As positioning/navigation/timing (PNT) based applications continue to expand strongly<br/>in consumer and commercial segments, demand is also growing for uninterrupted, and ubiquitous<br/>access to position/location information in all environments, indoors and outdoors. The<br/>standard ‘global navigation satellite system (GNSS)’ receiver works well in outdoor line-of-sight<br/>environments. However, in dense urban settings and indoor environments, due to signal<br/>multipath, shadowing, noise and interference caused by communication system operating in<br/>adjacent frequency bands, the accuracy of GNSS receivers is severely degraded rendering PNT<br/>solutions useless for many applications.<br/>For obtaining the position solution, the signal coming from the satellite is correlated with<br/>the reference signal available at navigation receiver. Standard receiver takes the advantage of<br/>triangular shape of the correlation function, but in case of multipath it is effectively the some of<br/>many such triangles each corresponding to a multipath component. The disturbance caused in<br/>correlation function leads to an error in position solution. In urban and indoor environments,<br/>along with multipath, shadowing and interference are additional problems that are responsible<br/>for low received signal power. In such a case of weak signals, receiver acquisition fails and no<br/>position solution is obtained.<br/>In the presented work we provide novel algorithmic solutions to mitigate signal multipath<br/>and interference effects on PNT solutions in dense urban settings and indoor environments. The<br/>performance improvements of the proposed solutions are demonstrated using recorded GNSS<br/>satellite signal and MATLAB based software defined GNSS receiver and the results show that<br/>these methods perform within desired accuracy limits in very general multipath and interference<br/>environments. The comparison shows that performance of these algorithms is far better than the<br/>existing state of art solutions."<br/> |
