COSMIC-2 Precise Orbit Determination [PDF]

, 2019
We present initial results for post-processed GNSS orbit and clock estimation for the FORMOSAT-7/COSMIC-2 (Constellation Observing System for Meteorology, Ionosphere, and Climate) constellation. The six COSMIC-2 satellites launched on June 25, 2019 into a 24 deg inclination, ~725 km circular orbit. The primary Tri-GNSS Radio-occultation Receiver System

Cancer-associated mutations in endometriosis reframe a benign disease through molecular oncology. [PDF]

Mol Oncol
This review aims to comprehensively analyse cancer‐associated somatic mutations (CAMs) present in endometriotic lesions, emphasizing their biological roles, spatial distribution and implications for translational applications in medicine. By contextualizing a benign state within a genomic framework, this analysis seeks to establish its value as a ...

Observation of Deep Occultation Signals in Tropical Cyclones With COSMIC-2 Measurements [PDF]

IEEE Geoscience and Remote Sensing Letters, 2022
Global navigation satellite system (GNSS) signals in the radio occultation (RO) technique using new measurements from constellation observing system for meteorology, ionosphere & climate (COSMIC-2) mission were observed very deep below the Earth's limb. Selected occultations collocated with severe tropical cyclones showed the existence

An Analysis Study of FORMOSAT-7/COSMIC-2 Radio Occultation Data in the Troposphere [PDF]

Remote Sensing, 2021
This study investigates the Global Navigation Satellite System (GNSS) radio occultation (RO) data from FORMOSAT-7/COSMIC-2 (FS7/C2), which provides considerably more and deeper profiles at lower latitudes than those from the former FORMOSAT-3/COSMIC (FS3/C).

Comparative Analysis of Binhu and Cosmic-2 Radio Occultation Data

Remote Sensing, 2022
Global Navigation Satellite System (GNSS) radio occultation (RO) technology has been widely used in Earth atmospheric detection and has a significant impact on numerical weather prediction (NWP), climate detection, and other fields. Cosmic-2 LEO-1 (C2E1) is a well-known RO data provider; however, its observations are confined to 45°S and 45°N. Recently,
