PITHIA-NRF services mitigating the socio-economic impacts of the upper atmosphere effects.

Many space weather phenomena perturb the upper atmosphere and influence the performance and reliability of several essential and costly space-borne and groundbased technologies on Earth, such as:

EARTH OBSERVATION (EO) SYSTEMS (E.G., LOW-FREQUENCY SAR), WHICH ARE AFFECTED BY:

  • Faraday rotation.
  • Ionospheric Scintillation.

UHF COMMUNICATIONS USED IN SATCOM THAT ARE ATTENUATED BY:

  • Ionospheric plasma bubbles.

POSITIONING, NAVIGATION, AND TIMING (PNT) WITH GNSS SATELLITES AND GROUND-BASED AUGMENTATION SYSTEMS (GBAS) THAT IS MADE INACCURATE BY:

  • Large total electron content (TEC) gradients.
  • Ionospheric plasma bubbles (leading to scintillations and ionospheric delay).
  • Travelling Ionospheric Disturbances.

ASTRONOMICAL OBSERVATION (AO) SYSTEMS (E.G., LOFAR), WHICH ARE RENDERED UNAVAILABLE BY:

  • Geomagnetic storms & auroral jets intensifications
  • Ionospheric plasma bubbles.

TERRESTRIAL RADIO SYSTEMS USING HF AND VHF COMMUNICATIONS, WHICH ARE DISRUPTED BY:

  • Polar Cap Absorption.
  • Sporadic E-layer.
  • Travelling Ionospheric Disturbances.
  • Ionization depletions.

SATELLITES IN LOW EARTH ORBIT (LEO), WHOSE ORBITS CAN BE AFFECTED BY THERMOSPHERIC DRAG.

PITHIA-NRF services will significantly contribute to predicting these effects and, thus, support the design of technologies mitigating their impacts.
