Accurate orbit determination of space debris is the foundation of Space Surveillance.
SpaceDyS develops advanced software solutions for processing radar and optical observations to build and maintain reliable debris catalogues.

DEBORB: Advanced Space Debris Cataloguing Software

Our proprietary library DEBORB is designed for high-precision orbit determination and data correlation.
Key capabilities include:

• Cataloguing “From Scratch”: DEBORB is capable of generating a complete database of orbiting objects starting from zero. By utilizing sophisticated Initial Orbit Determination (IOD) techniques, it can identify and characterize new objects that are not yet registered in existing databases.
• Processing Optical Survey Data: The library is optimized to process large volumes of data acquired by networks of optical survey telescopes. It excels at handling “tracklets” (short sequences of optical observations), transforming raw angular data into precise orbital information.
• Advanced Data Association: One of DEBORB’s core strengths is its ability to perform complex correlation and link-up tasks. It can accurately associate new observational data with known objects or recognize when multiple independent observations belong to a previously undiscovered debris fragment.
• High-Fidelity Dynamical Models: To ensure long-term tracking accuracy, the library incorporates advanced perturbative models. These include atmospheric drag, solar radiation pressure, and Earth’s non-spherical gravitational potential, which are essential for predicting the evolution of debris orbits.

DEBORB enables accurate debris tracking and long-term orbit prediction, supporting collision avoidance and SSA operations.

Re-entry Predictions
Uncontrolled decay of large LEO objects into the atmosphere poses a risk for people and infrastructures on ground. SpaceDyS can provide reliable predictions of re-entry time and location with the most accurate models available.
The team has successfully provided prediction campaigns for major satellites, including GOCE, using radar and GPS data to refine location accuracy.
