<p>Dear Colleagues,</p>
<p>We are pleased to invite you to contribute to a Special Issue of Remote Sensing entitled “GNSS in Real-Time Ionospheric Scintillation Monitoring”.</p>
<p>Message from the Guest Editors: Ionospheric scintillation represents a major challenge for Global Navigation Satellite Systems (GNSS) across all latitudes. Ionospheric scintillation directly impacts high-precision navigation users, demanding robust risk mitigation strategies. The growing demand for robust GNSS services in navigation, communication, and monitoring further underscores the urgent need for real time detection. Traditionally, specialized receivers measure signal fluctuations and compute scintillation indexes, but their limited coverage restricts global monitoring. Recent advances demonstrate that networks of geodetic GNSS receivers, combined with robust detrending techniques and real-time correction products, can provide reliable global monitoring. These developments are crucial for practical applications, offering operational support to industry and enhancing the safety of critical systems. This Special Issue invites contributions on innovative methods, datasets, and applications for real-time monitoring, including GNSS based techniques, modeling, and forecasting, with the aim of advancing both the understanding and mitigation of scintillation impacts worldwide.</p>
<p>Submission Deadline: 15 April 2026</p>
<p>Submit Online: http://mdpi.com/si/255980</p>
<p>We look forward to receiving your contributions.</p>
<p>Guest Editors:</p>
