BWI announces the selection of Anywaves and Hemeria as partners for the REVALTO mission, an ambitious project supported by CNES as part of the France 2030 program. Together, they develop a new generation of high-revisit space-based hydrological observation services.
Toulouse, September 17, 2025 – As part of the REVALTO project (REVisiting ALTimetry hydrOlogy), formerly known as H2R (High-Revisit Hydrology), the startup BWI (Blue Water Intelligence) announces that it has selected Anywaves and Hemeria as its industrial partners.
Both based in Toulouse like BWI, Hemeria and Anywaves will contribute their respective expertise to this ambitious project, which aims to develop a high-revisit hydrological constellation: Hemeria for the satellite platform, integration, and operations; and Anywaves for the design and production of the payload.
The objective of REVALTO is to produce frequent and accurate measurements of continental water levels (rivers, lakes, reservoirs) in order to advance scientific knowledge of the water cycle and to develop new innovative services, such as flood prevention and drought forecasting.
According to Jérémy Fain, CEO of BWI, « the technical challenges involved in developing satellites made it essential to work with partners whose DNA closely matches ours and whose technical expertise complements our own. We have full confidence in Anywaves’ ability to develop a miniaturized radar altimeter tailored to the mission’s objectives, and in Hemeria’s capacity to build a top-quality platform and operate satellites. It was therefore evident for us to call on these leading players in the French space ecosystem. »
As for Nicolas Capet, President of Anywaves, « This ambitious project aligns perfectly with ANYWAVES’ strategic roadmap. After having developed and delivered a full range of antennas and radio frequency products for satellites and payloads, the next logical step was to acquire the capability to provide RF radar payloads. Backed by our recognized experience and industrial expertise, we are fully committed to developing this particularly innovative payload, thereby contributing to the success of BWI’s ambitious mission. »
Finally, Nicolas Multan, CEO of HEMERIA, added: « We are delighted to support BWI in its REVALTO project. The mission’s major societal contribution brings special meaning to our participation. Moreover, it strengthens the production pipeline of satellites to be manufactured and delivered for our HP-EOS range. One more customer! »
The REVALTO project is part of the France 2030 program, jointly overseen by the Directorate General for Enterprise (DGE), the Directorate for Research and Innovation (DGRI), and the Directorate General for Armament (DGA), with the General Secretariat for Investment (SGPI), and operated by CNES (the French Space Agency) on behalf of the Ministry for Energy Transition (MTE).
