Principles of Dynasonde Navigator

Abstract

Dynasonde is an ideology of precision ionospheric radio sounding based on rigorously taking into account phase characteristics of a radio echo. Unique products of phase ionosondes intended for various Space Weather-related applications include: echo recognition and noise discrimination, echo classification into traces, scaling of standard ionospheric parameters, 3-D plasma density inversion (NeXtYZ) including true vertical profile with error bars, small-scale irregularity diagnostics, and vector velocities, all obtained directly and autonomously from ionogram data. Our report describes details of implementation of Dynasonde principles in operation of the web portal Dynasonde Navigator (http://dynserv.eiscat.uit.no) hosted by EISCAT.
