COSMIC-2 RFI Prediction Model Based on CNN-BiLSTM-Attention for Interference Detection and Location. [PDF]
Sensors (Basel)As the application of the Global Navigation Satellite System (GNSS) continues to expand, its stability and safety issues are receiving more and more attention, especially the interference problem. Interference reduces the signal reception quality of ground terminals and may even lead to the paralysis of GNSS function in severe cases.

Ionospheric scintillations studies using Spire and COSMIC-2 radio occultation and GOLD satellite data [PDF]
, 2023 Low-earth orbits (LEO) satellites have been harnessing the concept of GNSS radio occultation (RO) for several atmospheric applications. With the advent of CubeSat technology, many space companies are now extending the GNSS-RO for ionospheric and space weather studies.

Modeling impact of FORMOSAT‐7/COSMIC‐2 mission on ionospheric space weather monitoring [PDF]
Journal of Geophysical Research: Space Physics, 2013 For the past decade, the paucity of ionospheric observations has made it almost impossible to reconstruct the three‐dimensional structures of global ionospheric electron density.

Improving topside ionospheric empirical model using FORMOSAT-7/COSMIC-2 data
Journal of Geodesy, 2023 The precise description of the topside ionosphere using an ionospheric empirical model has always been a work in progress. The NeQuick topside model is greatly enhanced by adopting radio occultation data from the FORMOSAT-7/COSMIC-2 constellation.

Templates for Fitting Photometry of Ultra-high-redshift Galaxies
The Astrophysical Journal Letters, 2023 Recent data from the James Webb Space Telescope allow a first glimpse of galaxies at z ≳ 11. The most successful tool for identifying ultra-high-redshift candidates and inferring their properties is photometric template fitting.
