Interactive simulation tool for earth observation satellites
Under the Space Data Lab 3 initiative, we are currently working on a new demonstration tool, developed using the PASEOS Python package, designed to make the science of Earth observations more comprehensible and engaging for a broad audience. This tool will soon be available for hands-on exploration at AI Sweden's offices (in Stockholm and Gothenburg), providing an opportunity to engage directly with the principles of satellite-based Earth observation.

Understanding earth observations
Earth observations involve the systematic collection of data about the Earth's systems—land, oceans, and atmosphere—using satellite-based remote sensing technologies. These observations are critical for understanding climate processes, tracking environmental changes, and informing decision-making in fields such as agriculture, disaster management, and urban planning.
Our tool will illustrate these concepts by simulating the operation of Earth observation satellites, enabling users to gain insights into how orbital dynamics and data acquisition strategies influence our understanding of the planet.
The tool will offer a detailed graphical representation of a virtual satellite constellation, where users can configure and experiment with various orbital parameters. Key features include:
Satellite constellation design: Users will be able to deploy and customize virtual satellites, adjusting orbits and configurations to study their impact on data coverage and observation capabilities.
Real-time visualization of satellite operations: The simulation tracks satellite positions, observation footprints, and data acquisition in real time, providing a clear understanding of spatial and temporal data coverage.
Performance metrics analysis:
- Energy Management: The tool will model satellite power consumption, accounting for solar energy recharging and battery dynamics, to demonstrate the challenges of maintaining satellite functionality over long durations.
- Observation efficiency: Users will be able to analyze how satellite orbits and observation strategies maximize or limit the time spent observing specific regions of interest.
- Data transmission and communication: The simulation will visualize how satellites interact with ground stations and each other, illustrating the complexities of data transmission and storage management, including communication latencies and bandwidth limitations.
The simulation tool emphasizes the critical considerations in designing and operating Earth observation missions. Users will learn about:
- Trade-offs in satellite design: How energy constraints, observation requirements, and communication needs shape satellite and constellation design.
- Data quality and coverage: The relationship between orbital parameters and the quality and completeness of Earth observation datasets.
- Knowledge generation: The process of transforming raw remote sensing data into actionable information, highlighting the role of spatial and temporal resolution in different scientific applications.
Our demonstration tool is perfect for:
- Students and researchers: As a learning resource that bridges theoretical concepts with practical applications in satellite and Earth observation science.
- Policy analysts and environmental scientists: To gain a clearer understanding of how Earth observation data can inform research and policy decisions.
- General science enthusiasts: Offering a hands-on way to explore the scientific principles underlying satellite remote sensing and data generation.
This tool will soon be available for hands-on exploration at AI Sweden's offices in Stockholm and Gothenburg.
The demo tool will be available soon!
