Space Climate 7 Meeting Abstract
From solar maximum to solar minimum: higher order ionospheric effects on GNSS
Reza Ghoddousi-Fard (Natural Resources Canada)
Dispersive nature of ionosphere on GNSS frequencies enables the removal of most part of ionospheric delay using a combination of dual-frequency observations. The remaining ionospheric delay, usually refers to as higher order effects, can not be removed using dual-frequency combinations. As a by product of global and regional total electron content (TEC) mapping and ionospheric irregularity monitoring at the Canadian Geodetic Survey of Natural Resources Canada, higher order ionospheric effects are routinely being estimated at ionospheric pierce points observed from about 350 globally distributed GNSS stations of IGS network. In this presentation, higher order ionospheric effect during days of high and low solar activity are compared.
