Abstract

The space environment critically impacts human space activities and ground-based hi-tech systems.
Disturbances and irregularities in this environment,such as those affecting satellite navigation, necessitate large-scale, continuous monitoring asigni cant challenge over vast oceanic regions.
Supported by the Meridian Project II, we have developed the Low-latitude long range Ionospheric Radar (LARID). LARID enables the over-the-horizon detection of space environment over the Indian Ocean-West Pacific, providing a powerful means to monitor disturbances. This report will introduce LARID’s technical features and present its key findings in detecting equatorial plasma bubbles and traveling ionospheric disturbances.
