Summary

SKAISEN is an on-board AI-based cloud detection solution designed for optical EO missions. 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.

Seamlessly supports a range of commonly used sensors and data processing units, currently tested with Simera Sense cameras and boards equipped with Xilinx® ZynqTM SoC. More configurations and options will be added in the near future.

SKAISEN is available in three variants, giving customers the choice of a single component up to a comprehensive full mission Onboard Data Processing (OBDP) solution. The three variants are as follows:

SKAISEN Edge: It is a Standalone FPGA IP Core with AXI interface or a CPU-optimized binary to a specific embedded
processor. This powerful solution offers on-board cloud filtering capabilities that effectively identify cloudy imagery and significantly reduce downlink costs.

SKAISEN OS: Customized operating system designed to work seamlessly with SKAISEN Edge on Xilinx® ZynqTM 7000 and Xilinx® ZynqTM UltraScale+TM boards. SKAISEN OS offers flexibility and compatibility, allowing customers to easily update it with their own packages and software within the Linux environment.

SKAISEN Payload: SKAISEN OS delivered together with one of the Data Processing Units (DPU) available on the market. Zaitra has connections with numerous suppliers throughout the global supply chain. We have the ability to procure and configure a DPU specifically tailored to meet your mission requirements.

SKAISEN is available in multiple configurations. To ensure clear pricing, Zaitra has designed two types of licenses:

  1. SKAISEN spacecraft licensing
  2. SKAISEN instrument licensing

Key features

SKAISEN is available in three configuration variants:

  • SKAISEN Edge
  • SKAISEN OS
  • SKAISEN Payload

Flight heritage

SKAISEN Edge: The SKAISEN Edge running on Xilinx® ZynqTM Ultrascale+TM will be deployed on the TROLL 6U mission,
with a hyperspectral camera as the main mission payload. The mission launch is planned for Q4 of 2024. Additionally, there are more scheduled missions for 2024 that will utilize SKAISEN technology on board.

SKAISEN OS: Its compatibility currently extends to a satellite bus utilizing the Cubesat Space protocol. Thorough testing
and integration of drivers for the control and data readout of the SimeraSense xScape camera have been conducted. TRL 9 is expected to be reached on the mission in Q4 2024.

SKAISEN Payload: The SKAISEN payload, utilizing the board with the Xiphos Q8S module, will be deployed on the TROLL 6U mission with the hyperspectral camera as the main mission payload. The mission launch is planned for the Q4 of 2024.
