TechTIDE

Warning and Mitigation Technologies for Travelling Ionospheric Disturbances Effects(TechTIDE). Travelling Ionospheric Disturbances (TIDs) are plasma density fluctuations that propagate as waves through the ionosphere at a wide range of velocities and frequencies. TIDs constitute a threat for operational systems using predictable ionospheric characteristics as they can impose significant disturbances in the ambient electron density and Doppler frequency shifts on HF signals. TIDs can have multiple effects in the operation of aerospatial and ground-based infrastructures and especially in the European Geostationary Navigation Overlay Service (EGNOS) and Network Real-Time Kinematic (N-RTK) services, in High Frequency (HF) communications, in radio reconnaissance operations and in Very High Frequency – Ultra High Frequency (VHF-UHF) radiowave propagation.

Because of the high occurrence frequency of TIDs (almost daily), and the variety of their characteristics regarding their velocity, propagation direction and amplitude, their identification and tracking is very complicated and has not been achieved in operational service mode. The overarching objective of the TechTIDE project is to design and test new viable TID impact mitigation strategies for the technologies affected and in close collaboration with operators of these technologies, to demonstrate the added value of the proposed mitigation techniques.
