Detection of the Unified Control Points for RPC Adjustment of KOMPSAT-3 Satellite Image

open access: yesKorean Journal of Remote Sensing, 2014
The KOMPSAT-3 can acquire panchromatic stereo image with 0.7 m spatial resolution, and provides Rational Polynomial Coefficient (RPC). In order to determine ground coordinate using the provides RPC, which include interior-exterior orientation errors, its adjustment is needed by using the Ground Control Point (GCP). Several thousands of national Unified

Impact of Two Radio Occultation Constellations on Numerical Weather Prediction: Polar‐Orbits Only and Mixed Polar‐Equatorial Orbits

open access: yesEarth and Space Science, Volume 13, Issue 10, October 2026.
Abstract This study explores the relative impact of two orbital configurations for Global Navigation Satellite System radio occultation (RO) observations in numerical weather prediction using observing system simulation experiments (OSSE). Three experiments are carried out: a Control experiment with no RO observations and two experiments with 14,000 RO

Assimilating GNSS Airborne Radio Occultation Bending Angles With MPAS–JEDI During a Sequence of Atmospheric Rivers

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Global Navigation Satellite System (GNSS) airborne radio occultation (ARO) observations, collected during Atmospheric River Reconnaissance (AR Recon) campaigns, enhance AR sampling beyond traditional dropsondes. Assimilating ARO bending angles requires a forward operator accounting for ARO geometry and proper integration in a data assimilation

Merge of sub-images from two PAN CCD lines of Kompsat-3 AEISS

open access: yesKSCE Journal of Civil Engineering, 2016
The Kompsat-3 Advanced Earth Imaging Sensor System (AEISS) camera contains two PAN CCD lines for a larger swath width. Merge of sub-images from individual CCD lines requires precise camera calibration before launch as well as in-flight calibration with a number of ground control points to determine the geometric relations between the CCD lines.

Implementation of the Deep Blue Aerosol Algorithm on Geostationary Satellite Data

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract National Aeronautics and Space Administration's Deep Blue (DB) aerosol project aims to produce consistent, long‐term climate data records of atmospheric aerosol properties using satellite observations. The DB algorithm has been extensively applied to low Earth orbit (LEO) sensors, including the Moderate Resolution Imaging Spectroradiometer and

Change Detection of Building Objects in High-Resolution Single-Sensor and Multi-Sensor Imagery Considering the Sun and Sensor’s Elevation and Azimuth Angles

open access: yesRemote Sensing, 2021
Building change detection is a critical field for monitoring artificial structures using high-resolution multitemporal images. However, relief displacement depending on the azimuth and elevation angles of the sensor causes numerous false alarms and ...

Orbital Decay of the Three SNIPE CubeSats During the Super Geomagnetic Storm in May 2024

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract The Mother's Day (Gannon) geomagnetic superstorm of May 2024 produced extreme thermospheric heating and expansion, resulting in enhanced atmospheric drag on low Earth orbiting (LEO) satellites. We investigate storm‐time thermospheric drag and density variability using three satellites of the Small‐scale magNetospheric and Ionospheric Plasma ...

Height‐Dependent Evolution of the Ionospheric Response to the May 2024 Superstorm: Global GNSS‐POD, GNSS‐RO, and Ground‐Based Observations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Capturing global ionospheric response during extreme geomagnetic storms remains a major observational challenge. During 10–11 May, 2024 superstorm, we investigate the height‐dependent response of the F‐region using multi‐constellation GNSS‐POD limb‐sounding measurements from COSMIC‐2, Spire, PlanetiQ, and FengYun‐3 satellites. Approximately 12,
