東亞地區多站與多系統電離層不規則體聯合觀測與研究(1/2&2/2)

Project Details

Description

Accurate and precise real-time specification and modeling of the ionospheric electron density (Ne) and irregularity are important to radio sky-wave communications and satellite navigation. Due to the success of FS3/COSMIC on remote sensing the ionosphere using the radio occultation (RO) technique, the joint U.S. and Taiwan RO team have moved forward with a COSMIC follow-on mission (called FS7/COSMIC2) that launched six low-inclination LEO satellites (24° inclination) in June of 2019. The FS7/COSMIC2 RO payload can receive multi-channel GPS and GLONASS satellite signals and be capable of tracking more than 5,000 RO observations per day. It is expected that denser RO observations will be used to accurately structure and model the Earth’s equatorial and low-latitude ionosphere. Further optimization analyses on regional ionospheric Ne and irregularity and corresponding validation works are also proposed. The supporting systems include a Vertical Incidence Pulsed Ionospheric Radar (VIPIR) network located in east Asia and more than 150 local ground-based GPS/GNSS receivers in Taiwan. The East-Asia VIPIR network includes nine systems allocated in Japan (four systems), Korea (two systems), Taiwan (two systems), and Philippines (one system). This study will address new objectives and results of GNSS RO remote sensing in the ionosphere as well as new opportunities for future ionospheric weather and/or space weather missions. Generally, 3D ionospheric Ne, F-layer scintillation and ionospheric weather and climatology, namely, its variations with each identified zone, altitude, season, and local time are proposed to be documented.
