Simulink® block that models noise acting on four different timescales

This block models multiband noise by adding four different band limited white noise signals, each one with its own power and time scale, with three of them being also filtered by a lowpass first order filter.

NOTE: I made this around 2005 in an effort to model the noise typically observed by a gps receiver. But it is a toy model and a very uneducaded guess. So it might be OK for a start but otherwide I do suggest you look at more authoritative sources as for example this one.
