説明

Ionospheric tomography is a technique to reconstruct ionospheric density profiles from various measurements. We have developed a real-time 3-D ionospheric tomography system over Japan by using total electron contents (TECs) derived from dual-frequency Global Navigation Satellite System (GNSS) signals measured by 200 receivers of GEONET over Japan [1]. The algorithm of the tomography is a constrained least-squares [2, 3]. The real-time 3-D tomography system has been running since March 2016 and produces 3-D ionospheric density profiles over Japan every 15 minutes with a latency of 6 minutes.
