Smartphone Carrier Phase TEC: A Study Across Ionospheric Spatio‐Temporal Scales
Space Weather, Volume 24, Issue 5, May 2026.Abstract This study explores the potential of dual‐frequency smartphones as accessible tools for citizen science in ionospheric research. While prior work by Smith et al. (2024, https://doi.org/10.1038/s41586‐024‐08072‐x) demonstrated global ionospheric monitoring using aggregated pseudorange Total Electron Content (TEC) data from millions of Android ...
