GNSS for environmental and atmospheric monitoring
Major sources of errors for Global Navigation Satellite Systems (GNSSs) are the signal propagation through the atmosphere, including ionospheric delay and scintillations, and the environmental natural interferences, such as multipath. If not properly modelled and mitigated, they can lead to significant errors in the positioning solution. At the same time, if the receiver is static and its position is known, it is possible to invert the problem and to process GNSS observables to characterize the effects along the signal propagation path. The systematic measurement of observables and the inversion of the typical positioning equation are the basis of GNSS atmospheric remote sensing. Algorithms for scintillations monitoring, detection and mitigation are being studied and implemented in software defined radio GNSS receivers, with the twofold objective to improve the positioning accuracy, continuity and reliability, and to investigate the physical phenomena characterizing the atmosphere.
