KONINKLIJKE STERRENWACHT VAN BELGIE

Their core work

The Royal Observatory of Belgium (ORB) is a federal research institution specializing in Earth sciences, solar physics, and planetary research. They study Earth's rotation, gravity, and magnetic fields, model planetary interiors, and contribute to space weather forecasting and asteroid defence. They also operate as a node in European research infrastructure networks for solid Earth science and astronomical observations, providing data services and access to specialized instruments.

What they specialise in

How they've shifted over time

In the early H2020 period (2015–2018), ORB focused on fundamental geophysics (Earth rotation via RotaNut), Mars science, and contributed to SWIR detector development and satellite navigation timing. From 2019 onward, the emphasis shifted strongly toward research infrastructure governance (EPOS SP, ESCAPE), space weather modelling, asteroid planetary defence, and open science data services — reflecting a move from pure observational science toward applied services and infrastructure sustainability. Their two most recent coordinated grants (MERCURYREFINEMENT, GRACEFUL) show continued strength in deep planetary and Earth interior physics.

ORB is evolving from a traditional observatory toward an infrastructure and data services hub, increasingly engaged in operational space weather forecasting and planetary defence — areas with growing policy relevance and commercial applications.

How they like to work

ORB primarily joins large consortia as a specialist partner (13 of 16 projects), but has demonstrated coordination capability on focused research topics where they hold deep domain expertise — Earth interior dynamics and planetary science. With 190 unique partners across 35 countries, they operate as a well-connected node in European astronomy and geoscience networks rather than a closed group with repeat partners. This makes them easy to integrate into new consortia where geophysics, planetary science, or space weather expertise is needed.

ORB has collaborated with 190 distinct partners across 35 countries, placing them at the centre of pan-European astronomy and Earth science networks. Their partnerships span major ESFRI facilities (CERN, ESO, JIVE) and research institutions across virtually all EU member states.

What sets them apart

ORB sits at a rare intersection of Earth interior geophysics, planetary science, and operational space weather — few European research centres cover all three. Their long heritage as a national observatory gives them access to century-long geophysical data records that are irreplaceable for validation and calibration work. For consortium builders, they bring both scientific depth and infrastructure experience, able to contribute precision measurements, modelling, and data services in a single partnership.

Highlights from their portfolio

• GRACEFUL
  Their largest grant (EUR 2.89M) as coordinator, using synergistic gravity and magnetic field observations to probe Earth's deep interior — a flagship project for the institution.
• RotaNut
  EUR 2.5M ERC Advanced Grant as coordinator, studying Earth's rotation and nutation — demonstrates world-class leadership in fundamental geophysics.
• NEO-MAPP
  Planetary defence project combining asteroid modelling with payload development — connects ORB's planetary science to a high-profile applied domain with growing policy and commercial interest.
