The European Space Agency (ESA) low Earth orbit (LEO)-PNT satellite program, approved at last year’s (2022) ESA ministerial conference, will soon begin testing a mini-constellation of at least ten satellites, placed in orbit some hundreds of kilometers above the Earth’s surface. Conventional GNSS systems, like those used by Europe’s Galileo program, utilize medium Earth orbit (MEO) satellites, about 23,000 kilometers from Earth.

Safran Electronics and Defense (France) is leading the ACHILE consortium (‘Augmented capability for high-end soldiers’), aimed at designing advanced soldier systems with enhanced capability suites. In June, 2023, the European Commission awarded ACHILE a €40-million grant, making it one of the main projects funded under the European Defense Fund 2021.

Interference, both intentional and unintentional, is a major concern for those who rely on PNT. Space weather is among the natural threats that can result in GNSS errors and disruptions, and should be top of mind with Solar Cycle 25 on its way, shaping up to be the most active cycle in 20 years. It will disrupt GNSS operations—we just have to be ready for it.

ION’s JNC brings industry together to solve PNT challenges
Reliable access to PNT is critical for the warfighter, but that’s becoming more difficult as threats like jamming and spoofing continue to grow.

GMV NSL Ltd and Thales Alenia Space have presented the results of the NAVISP EL1 034 project, ‘AI-Enabled Baseband Algorithms For High-Fidelity Measurements’ (AlnGNSS). Using selected AI-enabled algorithms, the project demonstrated some significant improvements in PVT performance compared to conventional GNSS PVT methods. However, the overall impact of AI was not substantial.

Low Earth orbit (LEO) constellations offer a new avenue for assuring PNT. With satellites closer to the Earth, they provide stronger signals and improved positioning accuracy with rapidly changing geometry. They complement GNSS resiliency, security and precision for PNT, making LEO an attractive alternative PNT option for the industry to pursue.
