Galileo relies on ground-based uplink stations (ULS) to maintain accurate positioning for users worldwide. These stations transmit essential data to the satellites, including the information required to compute the satellites’ orbits and clock corrections. Traditionally, such messages are sent using dish antennas. However, a new type of ground uplink antenna – a phased array antenna – was recently tested at the European Space Agency’s (ESA) site in Redu, Belgium. Developed under ESA’s Horizon 2020 programme for R&D, which aims to keep Galileo up to date with the latest innovations, this …
The Japan Aerospace Exploration Agency, or JAXA, and Mitsubishi Heavy Industries said Wednesday they will launch an additional Michibiki positioning satellite aboard an H3 rocket on Dec. 7.
The launch is scheduled to take place between 11:30 a.m. and 12:30 p.m. from the Tanegashima Space Center in Kagoshima Prefecture.
The Michibiki satellite system serves as the Japanese version of GPS, offering precise positioning to centimeter-level. Currently, five Michibiki satellites are in operation.
The Japanese government plans to launch another Michibiki satellite by the end of the current fiscal year, aiming to complete a …
NSG Geospatial Services, owned by Neo Space Group (NSG), a PIF Company, announced the launch of its innovative geospatial platform, “NeoMaps”. This launch underscores the company’s role in supporting the Kingdom’s efforts to develop geospatial capabilities and enhance digital sovereignty in this vital sector, contributing to Saudi Arabia’s leading position in the geospatial economy at both regional and global levels.
The NeoMaps platform serves as an integrated digital gateway, allowing users from security, civil, and commercial sectors to explore, visualize, and analyze geospatial data through a unified and easy-to-use interface. The …
Institute of Navigation awarded Dr. Jason Anderson its Bradford W. Parkinson Award on September 12, 2025, during the ION GNSS+ 2025 conference in Baltimore, Maryland, for his thesis: Designing Cryptography Systems for GNSS Data and Ranging Authentication.
Jason Anderson received his PhD from Stanford University where his research in the Stanford GPS Lab pertained to constructing efficient cryptosystems for GNSS.

Dr. Anderson has worked at SpaceX, General Atomics, and is currently working at Xona Space Systems as …
Institute of Navigation’s (ION) Satellite Division awarded Logan Scott its Johannes Kepler Award on September 12, 2025, during the ION GNSS+ 2025 conference in Baltimore, Maryland, for sustained contributions to satellite navigation signal design, recognition and mitigation of interference and spoofing threats to GPS, and advocacy for civil GNSS assurance.
Logan Scott’s seminal contributions to satellite navigation over his 45+ year career include digital receiver design; early recognition of threats to GPS from interference and spoofing; invention of location-based encryption, “J911” crowd-sourced geolocation of interference sources; and use of cryptographic signal …
The European Space Agency (ESA) has confirmed plans to launch the first two satellites in its low-Earth orbit (LEO) positioning navigation and timing (PNT) constellation in the second half of December 2025. The launch will use a Rocket Lab Electron Vehicle, marking Europe’s first venture into LEO-based satellite navigation.
The LEO-PNT in-orbit demonstrator mission, called Celeste, aims to test satellite navigation capabilities in LEO and evaluate its integration with existing medium-Earth orbit (MEO) systems.
Celeste features a constellation of ten satellites that will fly close to Earth to test innovative signals across various frequency …
The E-GIANTS (European GNSS Improved Authentication Solutions) project was commissioned by the European Commission and technically supervised by EUSPA. The project responds to the growing threat posed by quantum computing to traditional cryptographic methods, which could compromise the security of GNSS services in the coming decade. The study highlights that while quantum computers threaten classic asymmetric cryptography (like RSA and ECDSA), symmetric mechanisms—properly configured—remain secure, guiding the project’s design choices.
The project’s scope encompassed three main work objectives:
SBAS and OSNMA Key Management: Focused on developing a comprehensive authentication solution for Satellite-Based Augmentation Systems (SBAS) and the …
Verra has published a digital soil mapping (DSM) tool that facilitates the robust and verifiable quantification of greenhouse gas emission reductions and carbon dioxide removals in agricultural land management (ALM) carbon projects. VT0014 Estimating organic carbon stocks using digital soil mapping, version 1.0 provides guidance for the development, calibration, and validation of data-driven modeling methods to estimate soil organic carbon (SOC) stocks in a spatially explicit manner, including model uncertainty estimations. Because the tool is based on robust, up-to-date science and novel technologies, such as remote sensing, it enables ALM projects to …
The Department of Posts (DoP), has signed a Memorandum of Understanding (MoU) with ESRI India Technologies Private Limited (ESRI India), a Geographic Information System (GIS) software and solutions provider.
Under this MoU, DoP will be able to use Esri India’s high-resolution imagery and street basemaps for its DIGIPIN portal. The collaboration will also enable the integration of DIGIPIN with Esri India’s Living Atlas portal, thereby making it accessible to the larger GIS community. Further, ESRI India will provide technical support to the DoP for seamless integration of their services for DIGIPIN.
This …
Taiwan, highly exposed to natural disasters, has transformed its disaster management through the Taiwan National Federated Research Data Repository. Powered by the datacube engine rasdaman, this platform integrates satellite imagery, UAV data, and IoT sensor streams across agencies, overcoming long-standing silos. By enabling real-time AI analytics, 3D flood simulations, and secure inter-agency data sharing, it enhances national resilience and supports evidence-based decision-making.
Historically, government agencies collected and stored Earth observation data in isolated silos, preventing timely sharing and reducing interoperability. This fragmentation hampered rapid decision-making during emergencies. To overcome these limitations, Taiwan launched …
