The ionosphere is one of the major error sources in Global Navigation Satellite System(GNSS) positioning,navigation and timing.Estimating the ionospheric delays precisely is of great interest in the G
Microporous hypercross-linked conjugated quinonoid chromophores represent a novel class of amorphous polymers, synthesized by the reaction of anthracene with di
The coefficients of the Global Gravitational Models(GGMs) define the external gravitational field of the Earth.In many geoscience applications and gravity interpretations these coefficients are routin
