SKAISEN is an onboard cloud detection solution designed for Earth Observation missions and a wide range of optical sensors.

SKAISEN can save costs associated with data transfer while empowering mission autonomy and supporting its purpose for space missions.

Powered by AI algorithms, SKAISEN detects pixels polluted by clouds directly onboard the spacecraft. SKAISEN offers multiple benefits, such as cost reduction by avoiding the download of unnecessary pixels, saving communication bandwidth for more valuable data, and faster access to critical data through prioritization.

SKAISIEN is currently compatible with any Simera Sense Camera and supports deployment to hardware units with an ARM CPU and FPGA. The full product will be demonstrated on the upcoming TROLL mission in Q4 2024, incorporating a hyperspectral camera and DPU payload provided by Zaitra. Additionally, there are scheduled missions for 2024 utilizing SKAISEN technology onboard.
