The 6U nanosatellite (measuring 20 cm × 10 cm × 34.05 cm) will transmit remotely sensed data from Hungary once in orbit, focusing on monitoring and forecasting drought-prone areas.

Funded by an EU grant, the project addresses the increasing need for digital agro-meteorological data driven by the rapid growth of precision agriculture in Hungary. The primary objective of WREN-1 is to forecast areas at risk of drought by providing frequently updated data, aiming to mitigate drought-related damages in the country.

WREN-1 will assess topsoil moisture content and monitor vegetation development using its onboard multispectral imaging system. The system will capture data with a ground resolution of 16 x 16 meters over nearly 10,000 square kilometers in a single pass. It will collect data in visible, near-infrared, and short-wave infrared wavelengths, providing detailed insights into vegetation growth. The satellite’s ability to photograph areas sideways in addition to directly below its path will enable more frequent imaging of specific areas.

After processing, the satellite images will provide high-resolution biophysical and biochemical data, which will be analyzed using automatic learning algorithms. WREN-1 is designed to orbit at an altitude between 515 and 520 km from the Earth’s surface, circling the Earth 15 times a day. The satellite, with an expected operational life of three years, will be operated by C3S Ltd. throughout its mission.

Upon reaching orbit, the satellite’s first task will be to establish communication with the ground station, followed by the activation of onboard subsystems. The subsystems will generate necessary power, control cameras, and establish required connections. The position stabilization subsystem will align the cameras, after which the first images will be captured and transmitted to the ground station for further analysis by the research team.

The WREN-1 CubeSat is scheduled for launch as part of Falcon 9’s Transporter-11 mission to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California on Friday, August 16.
