GNSS and PNT security deployed at World Economic Forum

Dimetor is providing its NAVSentry airspace situational awareness system to the World Economic Forum annual meeting, in support of the Austrian Armed Forces. The meeting is taking place this week in Davos, Switzerland, close to the Austrian border. NAVSentry is an AI-powered platform for detecting GNSS disruptions in real time, combining different technology layers and securing position, navigation and timing (PNT) data across autonomous and crewed systems from multiple data sources.

The system is providing insights into the integrity of GNSS signals to strengthen the Austrian Armed Forces’ ability to monitor, secure and protect the airspace against threats, including including jamming and spoofing attempts targeting the airspace and critical PNT infrastructure. The enhanced situational awareness strengthens the ability to detect anomalies, assess potential threats, and coordinate protective measures across both the physical and cyber domains. www.dimetor.com

Upgraded AI for GPSdenied drone operations

Safe Pro Group has announced the deployment of upgraded artificial intelligence algorithms to its patented Safe Pro Object Threat Detection technology. The enhanced capabilities enable rapid battlefield image analysis, including 2D and 3D modeling and explosive threat detection from virtually any drone video feed, and were developed following real world exercises in Ukraine based on end user feedback. safeprogroup.com

Advance NTN integration and interoperability

The Mobile Satellite Services Association (MSSA) has released its Reference Architecture document, offering strategic recommendations to accelerate the development, deployment, and global integration of open and interoperable NonTerrestrial Network (NTN) solutions.As satellite communications advance, NTN systems are increasingly vital to extending connectivity to remote and underserved regions, while complementing terrestrial networks. MSSA’s Reference Architecture emphasizes the importance of systemlevel design to ensure consistent device performance and seamless user experiences.

Developed by the MSSA Technical Committee’s Reference Architecture Work Group, the document addresses key challenges and outlines best practices across the entire service delivery chain, from satellite constellations and ground infrastructure to mobile devices, to meet growing demands for high-speed, reliable, and secure connectivity. www.mss-association.org

Anello launches Aerial INS

Anello Photonics has launched the Anello Aerial inertial navigation system (INS), a compact, high-performance inertial navigation system built around the company’s Silicon Photonics Optical Gyroscope technology and integrated with multi-band GNSS receivers. The Anello Aerial INS is built for demanding aerial platforms, including BVLOS UAS, maritime/shipborne VTOL UAS, ISR/ special-mission aircraft, heavy-lift and cargo drones, and other autonomous aerial vehicles. www.anellophotonics.com

Space Force ends Resilient GPS program

The U.S. Space Force has ended an exploratory effort to add smaller, lowercost navigation satellites to bolster the GPS, shelving a program that had been identified as a priority. The effort, known as Resilient GPS, or R-GPS, began in 2024 and funded three industry teams to develop designs and early prototypes for alternative navigation satellites. The Space Force confirmed it does not plan to move forward with deployments or on-orbit demonstrations.

In September 2024, the Space Force selected Astranis, L3Harris Technologies and Sierra Space to develop concepts for smaller, more cost-effective navigation satellites based on commercial designs. spacenews.com
