Session Abstract.</span></b></p>
<p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;text-align:justify;text-indent:35.4pt;line-height:150%;font-size:11pt;font-family:Calibri,"sans-serif""><span lang="EN-US" style="font-size:12pt;line-height:150%;font-family:"Times New Roman","serif"">The rapid advancement of GNSS technology, including new-generation
satellites, signals, and receivers, presents a wealth of new research opportunities.
These advancements, particularly the high-temporal-resolution GNSS signals, are
now more accessible to research teams worldwide. However, the full potential of
these technologies for studying the Atmosphere, Ionosphere, and other interdisciplinary
fields has yet to be fully realized. </span></p>
<p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;text-align:justify;text-indent:35.4pt;line-height:150%;font-size:11pt;font-family:Calibri,"sans-serif""><span lang="EN-US" style="font-size:12pt;line-height:150%;font-family:"Times New Roman","serif"">For a Space physicist, a GNSS receiver is often a
'black box'. Can we rely on a specific receiver manufacturer and their
expensive equipment to conduct crucial Atmospheric and Space physics studies?
Do the GNSS signals recorded with high temporal resolution truly enhance our
sensitivity and resolution for Ionosphere or Atmosphere explorations? Which
ionosphere-free combination is most effective for reconstructing TEC with
minimal noise and reliably detecting a weak earthquake or tsunami-related
ionospheric response? These are the practical questions that emerge
with the evolution of GNSS technologies.</span></p>
<p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;text-align:justify;text-indent:35.4pt;line-height:150%;font-size:11pt;font-family:Calibri,"sans-serif""><span lang="EN-US" style="font-size:12pt;line-height:150%;font-family:"Times New Roman","serif"">This section is devoted to new theories methods, and
GNSS techniques which allow looking far beyond the limitations in the Earth's
atmosphere, ionosphere and interdisciplinary fields such as geosciences, the
availability of new GNSS signals, receivers and GNSS receivers with the capability
of high sampling rate.</span></p></div>
