Global ionospheric maps (GIM) are commonly used ionospheric products in high-precision Global Navigation Satellite System (GNSS) applications. To meet the increasing demand for real-time (RT) applications, the International GNSS Service (IG...
Performance of ambiguity-resolved detector for GNSS mixed-integer model [0.03%]
GNSS混合整数模型无模糊度检测性能研究
Chengyu Yin,P J G Teunissen,C C J M Tiberius
Chengyu Yin
Teunissen (J Geod 98(83):1-16, 2024) proposed the ambiguity-resolved (AR) detection theory for GNSS mixed-integer model validation. In this contribution, we study the performance of the AR detector through analysis and simulation experiment...
Detection of ionospheric disturbances with a sparse GNSS network in simulated near-real time Mw 7.8 and Mw 7.5 Kahramanmaraş earthquake sequence [0.03%]
模拟近实时Mw 7.8和Mw 7.5卡赫拉曼马拉什地震序列中，利用稀疏GNSS网络检测电离层扰动
F Luhrmann,J Park,W-K Wong et al.
F Luhrmann et al.
On February 6, 2023 the Kahramanmaraş Earthquake Sequence caused significant ground shaking and catastrophic losses across south-central Türkiye and northwest Syria. These seismic events produced ionospheric perturbations detectable in Gl...
Prospects for meteotsunami detection in earth's atmosphere using GNSS observations [0.03%]
基于GNSS观测的地球大气中气象海啸检测前景研究
Panagiotis Vergados,Siddharth Krishnamoorthy,Léo Martire et al.
Panagiotis Vergados et al.
We study, for the first time, the physical coupling and detectability of meteotsunamis in the earth's atmosphere. We study the June 13, 2013 event off the US East Coast using Global Navigation Satellite System (GNSS) radio occultation (RO) ...

The Galileo High Accuracy Service (HAS) is a GNSS augmentation that provides precise satellite corrections to users worldwide for free directly through Galileo's E6 signal. The HAS service provides free PPP corrections from the Galileo cons...
The GUARDIAN system-a GNSS upper atmospheric real-time disaster information and alert network [0.03%]
GUARDIAN系统-GNSS高层大气实时灾害信息和警报网络
Léo Martire,Siddharth Krishnamoorthy,Panagiotis Vergados et al.
Léo Martire et al.
We introduce GUARDIAN, a near-real-time (NRT) ionospheric monitoring software for natural hazards warning. GUARDIAN's ultimate goal is to use NRT total electronic content (TEC) time series to (1) allow users to explore ionospheric TEC pertu...

Giancarlo Cerretto et al.
Extreme Energy Events (EEE) is an extended Cosmic Rays (CRs) Observatory, composed of about 60 tracking telescopes spread over more than 10 degrees in Latitude and Longitude. We present the metrological characterization of a representative ...
Bandwidth correction of Swarm GPS carrier phase observations for improved orbit and gravity field determination [0.03%]
改进轨道和重力场确定的SWARMGPS载波相位观测带宽校正
Lucas Schreiter,Oliver Montenbruck,Franz Zangerl et al.
Lucas Schreiter et al.
Gravity fields derived from GPS tracking of the three Swarm satellites have shown artifacts near the geomagnetic equator, where the carrier phase tracking on the L2 frequency is unable to follow rapid ionospheric path delay changes due to a...
