Welcome to the website of the Mistrale project. The Mistrale project aims at providing soil moisture maps using GNSS Reflectometry, to decision makers in water management, like farmers and water boards and nature management. The project develops a prototype sensor embedded on a dedicated RPAS platform. Mistrale wants to integrate various technologies to reach commercialisation with these GNSS-R based soil moisture maps.

Stabilized antenna for Mistral

For the Mako drone a stabilized antenna is designed and test, see the video below. With this stabilized antenna the GNSS-R signals are always picked up straight under the drone, even in a turn.


Cyclone demonstration

Mistrale produced a video about the field demonstration of the cyclone. A fixed wing drone with the ability of vertical take-off and landing.


Measurement campaign December

Last Friday (9-12-2016) Mistrale held a measurement campaign. With excellent effort and team-work a lot of data is collected for the validation of the sensor and system. This will forms the basis for the next year measurements. Now all the data from the ground measurements and the different airborne sensors has to be compared.

Mid-Term Review (MTR)

On 7 July 2016 the consortium held its Mid-Term Review (MTR) in Toulouse hosted by our partner GET. This means that the project is now halve way. In the meeting the overall project status is reviewed.

8 July test flight

On the 8th of July the Mistrale consortium had a test day. The new prototype of the sensor was tested. The long range Boreal operated by L’Avion Jaune is used for that test flight. The Boreal is the RPAS that Mistrale will use in future for the larger Missions like research flights and mapping large areas for nature and water management. The boreal is able to flying for 10 hours while carrying the heavier Mistrale sensor of 1.5kg.
