SKAISEN is a complete end-to-end decision intelligence service capable of delivering actionable insights directly from orbit. SKAISEN is designed to support Earth Observation missions and the data end-users at the same time. Regardless of the sensor and processing unit integrated onboard the satellite, SKAISEN optimises bandwidth and reduces latency by effectively filtering out non-relevant data. The system eliminates up to 90% of noisy data and ensures information delivery to the decision makers in minutes rather than hours or days.
Objectives of the Product

Earth Observation missions generate a vast amount of data, which often presents key information for decision makers. These missions commonly collect hundreds of gigabytes per day, making it impossible to download back to Earth in a cost-effective way. However, up to 90% of this data is noise lacking any added value and thus cannot be further utilised by the end users. SKAISEN has the capability to detect, analyse, and prioritise objects of interest within non-cloudy images. This enhancement addresses two critical challenges in satellite operations:

  1. Bandwidth Optimisation: By identifying both unusable (cloudy) data and non-relevant clear imagery, the system will dramatically reduce unnecessary downlink volume, preserving precious bandwidth for truly valuable data.
  2. Latency Reduction: By performing object recognition directly onboard the satellite rather than waiting for ground processing (which typically occurs hours or days later), SKAISEN will significantly reduce the time between image capture and delivery of actionable intelligence to end users.

SKAISEN is designed to be highly reusable and independent of the sensor and processing unit selected for the mission. This ensures its availability for any Earth Observation mission and its highly competitive price. By leveraging the AI-driven SKAISEN solution, customers can significantly reduce their costs associated with the ground segment infrastructure while maximising the valuable data downlink, as well as reducing the time to get to actionable data to the end-users.


Customers and their Needs

The key customer segments targeted by SKAISEN are Mission Owners, System Integrators, Payload Developers and Mission Operators, Governmental and Commercial Terrestrial Customers, and Maritime Security Operators.

The main challenges of these customers in data access are:

  1. Downlink capacity is wasted with unusable data instead of transmitting actionable information
  2. Wasted downlink resources increase latency and delay end-user access to valuable data
  3. Raw data from optical sensors is often contaminated by unusable pixels or scenarios, which could be mitigated
  4. Mission managers and operators spend significant time on human-centric operations that could be automated
  5. Slow access to critical data
  6. If the AIS system is turned off, it is not simple to perform checks on illegal, security or unregulated activities.

SKAISEN aims to bring a customer-friendly solution for acquiring valuable data only, reduce mission costs and time to delivery.ly solution for acquiring valuable data only, reduce mission costs and increase mission profits.


Targeted customer/users countries

Mission Owners, System Integrators, Payload Developers and Mission Operators all over the world, focusing on Earth Observation missions, as well as Governmental and Commercial Terrestrial Customers, together with Maritime Security Operators.


Product description

SKAISEN is a comprehensive decision intelligence service for satellite operations, transforming raw imagery into actionable insights directly in orbit. The system combines advanced AI algorithms with optimised hardware implementation to enable real-time data analysis and selective transmission, addressing critical challenges in bandwidth optimisation and latency reduction for Earth Observation missions.

SKAISEN operates as an integrated system with focus on processing data in real-time aboard satellites and providing infrastructure for receiving, decrypting, and integrating the resulting insights. This dual architecture enables flexible deployment across diverse satellite platforms and ensures access to relevant information in minutes.


Added Value

The principle of how SKAISEN works is described in the picture below. After the satellite collects imagery, SKAISEN processes the data and extracts valuable data only, which is then sent to Earth. This approach optimises downlink by minimising unnecessary data transmission and reducing latency.

There are several views on how to optimise data transfer to Earth. The most common approach is processing data before transportation. There are already available onboard data processing products in the market. The difference between them and SKAISEN lies in their reusability.

SENSOR INDEPENDENCE: While the existing products are operable, e.g., in the visible spectrum, SKAISEN is sensor independent, regardless of whether the optical sensor operates as monochromatic, RGB, multispectral or hyperspectral. The flexibility in choosing the right camera for the mission remains with the customer.

DPU INDEPENDENCE: Whether a single software solution or the entire payload is needed, SKAISEN offers both.

HERITAGE: SKAISEN demonstrated its first capabilities during the VZLUSAT-2 mission in the summer of 2022.


Current Status

SKAISEN has completed the first phase, focusing on onboard cloud detection, and achieving Initial Release Status with validation in laboratory environments with two strategic validators. In the next phase, the product will be developed to present a comprehensive decision intelligence solution, addressing the growing demand for real-time actionable insights in latency-sensitive applications.
