Europe's Navigation Tech Takes Off with Rocket Lab
New ZealandThu Jun 26 2025
Europe is teaming up with Rocket Lab to send two small satellites into space. These satellites are part of a bigger plan to test new navigation technology. The goal is to create a system that can help with positioning, navigation, and timing from low Earth orbit.
The satellites, called Pathfinder A, were built by two different companies: GMV and Thales Alenia Space. They are small, weighing between 20 and 30 kilograms each. The plan is to launch them from New Zealand by December. The satellites will operate for at least six months, testing key technologies and securing important frequencies.
This mission is crucial for Europe. It shows that despite efforts to become self-sufficient in space launches, Europe still relies on American companies for some missions. European rockets like Ariane 6 and Vega C are too big for these small satellites. Newer, smaller European rockets are in development but aren't ready yet.
The Pathfinder A satellites are just the beginning. Eight more satellites, called Pathfinder B, will follow by 2027. These will be larger and incorporate lessons from the first two. The ultimate goal is a full constellation of about 300 satellites. This system would augment the existing Galileo constellation and provide more resilient navigation services.
The satellites in low Earth orbit have an advantage. They are closer to Earth, so their signals are stronger. This makes them harder to jam. They could also be equipped with detectors to locate sources of jamming. This technology is important for the future of Europe's navigation system.
The full constellation is likely to be funded in the next European Union budget cycle, starting in 2028. The European Space Agency will seek funding for technology development and testing at its upcoming ministerial conference in November. This mission is a step towards securing Europe's future in space navigation.

Will the satellites need to take a detour if they encounter any space debris on their way to orbit?
How does the reliance on Rocket Lab for launching European satellites challenge the notion that Europe has resolved its launcher crisis?
What are the potential risks of depending on non-European launch providers for critical navigation technology demonstrations?
