Some airlines and military aircraft, including the Australian commercial airline Qantas, are receiving radio interference and GPS jamming from alleged Chinese warships in the Asia Pacific, report Australia Aviation and The Guardian.
The International Federation of Air Line Pilots’ Associations (IFALPA) released a statement acknowledging the reports of interference and recommended that pilots carry on, not respond to the warships and report all incidents to air traffic control.
“IFALPA has been made aware of some airlines and military aircraft being called over 121.50 or 123.45 by military warships in the Pacific region, notably South China Sea, Philippine Sea, East of Indian Ocean. In some cases, the flights were provided vectors to avoid the airspace over the warship. We have reason to believe there may be interferences to GNSS and RADALT as well,” the statement noted.
Further recommendations from IFALPA include notifying company dispatchers of the attempted contact and completing an ASAP report or other company safety report for non-ATC communication or GNSS interference.

Thales Alenia Space has signed a €43 million contract for the Euro High-Altitude Platform Systems (HAPS) demonstration project. EuroHAPS was selected by the European Commission on July 20, 2022, for collaborative defense research and development projects from the European Defense Fund.
EuroHAPS aims to develop several stratospheric demonstrators for missions designed to improve intelligence, surveillance and reconnaissance and communications capabilities. Project partners include companies from Italy, Spain, Germany and France.
The project will conduct flight demonstrations for three types of complementary stratospheric platforms: A reduced-scale Stratobus from Thales Alenia Space, a solar-powered airship designed for long-endurance missions and offering large payload capacity, Hybrid High Altitude Airship from the Italian Aerospace Research Centre capable of generating extra lift with a wing airfoil, and autonomous stratospheric balloon system from ESG and TAO consisting of a series of three altitude-controllable balloons.
These three types of platforms are complementary and feature different operating times, capacity and operational restrictions. They will give Europe a broad spectrum of solutions to meet a variety of different requirements.
The platforms will test a range of missions, including lidar observation to detect and classify targets at sea or on land and the ability to detect them in environments with vegetation cover. Communications intelligence and electronic intelligence missions will also be tested, as well as a meshed broadband communications network for air and land players.
HAPS offer a new opportunity to complement ground-based, satellite-based or airborne assets with unique capabilities tailored to operational requirements. These flight demonstrations of HAPS will enable demonstrations of different platforms and address the main technical risks associated with these new technologies while refining operational requirements to ultimately enable development of future HAPS systems.
An MQ-9 Reaper UAV has collided with a Russian Su-27 fighter jet after it tried to spray the UAV with jet fuel, reports ABC News. The U.S. European Command has released a video that was taken from a camera the bottom of the UAV and shows the moment the collision occurred.
The Russian fighter jet took two passes at the UAV. During the second attempt to spray the UAV with jet fuel, they collided. Communication with the UAV was lost momentarily after the collision.
From the video, one of the propeller blades of the UAV seems to be damaged.
GMV has been selected by the European Space Agency (ESA) and the European Union Agency for the Space Programme (EUSPA) to develop the Galileo second-generation system test bed (G2STB). The G2STB will provide ESA with a key system verification and validation facility in support of its role as Galileo system development prime, enabling a wide range of Galileo system monitoring, troubleshooting, prototyping and experimentation activities.
GMV will deliver four G2STB versions over five years. Among these modules, the G2 high accuracy service (HAS) data generator and monitor aims to improve the Galileo HAS that was declared operational in January.
Other early capabilities of the G2STB include an upgraded orbit determination and time synchronization facility — capable of processing inter-satellite link data, a time service monitoring module, an integrity support message generator, a signal authentication service, an authentication validation module, an emergency warning service module, an ISL simulator and a G2G message composer.
The G2STB project aims for a smooth transition from the Galileo first-generation to the second-generation, building onto the G1G legacy system tools. The G2STB is one of the key infrastructure elements that ESA is developing for the correct functioning of the Galileo second-generation satellites.
The G2STB will eventually replace and upgrade the capabilities of the two first-generation facilities, the Galileo system evaluation equipment and the time and geodetic validation facility (TGVF-X). The latter, developed and operated by GMV over the last decade, has played a key role in monitoring the Galileo signals and system validation activities during the Galileo exploitation phase. The TGVF-X is also contributing to the early validation of new capabilities and elements being rolled out in recent and upcoming Galileo System updates.
In parallel to the development phase, the G2STB will help upgrade the network of Galileo experimental sensor stations to process new signals and capabilities to ensure the availability of a G2-capable, worldwide, multi-constellation network of receivers and bit-grabbers — independent from the operational Galileo sensor stations.
The Navigation Support Office at the Mission Control Centre of the European Space Operations Center (ESOC) has been tasked with providing independent precise orbit determination for European space missions. ESOC, which is based in Darmstadt, Germany, is a part of the of the European Space Agency (ESA). ESA aims to use high-quality signals from Galileo alongside GPS to sharpen the orbital positioning levels for future space missions.
The Navigation Support Office has used the positive results of the Copernicus Sentinel-6 mission — one of the first missions to fly a joint Galileo-GPS capable receiver, which improved positioning capabilities — to prove to ESA mission teams that future missions can harness the power of Galileo to improve positioning accuracy.
Missions in the works
Proba-3 is a precision formation flying mission that aims to launch in 2024. The mission consists of two small satellites launched together that will separate to fly in tandem to prepare for future multi-satellite missions flying as one virtual structure. This mission will require millimeter-scale positioning precision and use a variety of positioning methods, including optical, radio and laser links and GNSS such as Galileo.
The ESA-supported Lunar Pathfinder will be launched into lunar orbit in 2024 with the intent of using it as a communication satellite for future moon missions. The spacecraft will incorporate a specially designed GPS- and Galileo-capable receiver that aims to demonstrate the feasibility of positioning fixes from 400,000 km away.
The future of Galileo
Galileo serves Europe and the world with accurate and reliable navigation services as well as a catalyst for future space missions — making it a critical aspect of both everyday life and the enhancement of accurate navigation. The constellation will continue to grow with 10 more Galileo first-generation satellites planned for launch in the next few years. Second-generation Galileo satellites with enhanced capabilities are being built for testing and qualification at ESA’s European Space Technology and Research Centre as well.
The University of New South Wales has developed an advanced GNSS receiver that can receive signals from GPS and Galileo satellites across multiple frequencies. The Australian Space Agency provided funding for the project via the International Space Investment initiative.
The receiver may play a key part in the future for Australian space missions.
Professor Andrew Dempster, director of the Australian Centre for Space Engineering Research (ACSER), led the development of the receiver and notes that it is an upgrade of Kea, a receiver made in Australia and New Zealand.
“The idea was to take that work (on Kea) and upgrade it for this multi-frequency, multi-system solution,” Professor Dempster said. “We needed to scale up the performance of many of the components on the boards – in particular, where the digital processors and hardware live.”
ACSER aims to have the receiver support upcoming satellite missions. The receiver can provide precise positioning, timing and velocity information. It enables satellites to produce higher quality images from space with better pointing.
Inertial Labs has launched its inertial measurement unit-P (IMU-P).
