Abstract
A device for handling multipath of a G.N.S.S. signal, is configured to: determine a spatial position, a clock time and measured multipath parameters comprising a relative delay and relative amplitude; communicate to a remote server the spatial position, clock time and multipath parameters; and receive processed multipath parameters as determined by the remote server. Systems comprising a plurality of such devices and their variants are described. Further aspects are described, in particular the exclusion of one or more satellites, the use of threshold schemes, pull/push modes, configurable refresh rates, quantization of positions, activation of additional sensors, filtering options, determination of merit factors for example as a function of the number of satellites in view and/or of signal-to-noise ratio, peer-to-peer schemes, as well as graphical display, audible sound or haptic feedbacks.
