Orbit determination process
Definition
The Orbit Determination Process is a critical analytical procedure used in the field of astrodynamics and space operations to accurately estimate and predict the orbital path of an object in space, such as a satellite or a piece of space debris.
The process involves collecting observational data from various sources, such as radar and optical sensors, and using it to calculate the object's current trajectory, velocity, and future positions.
This involves sophisticated mathematical models and algorithms to process and analyze the data, accounting for various forces affecting the object's motion, such as gravitational pulls from Earth and other celestial bodies, atmospheric drag, and solar radiation pressure.
The outcome of an orbit determination process is essential for several key activities, including space situational awareness, collision avoidance, satellite navigation, mission planning, and maintaining the safety and sustainability of space operations.
It ensures that space assets are operating in their intended orbits and helps mitigate the risks associated with space debris and other potential threats in the orbital environment.
Why orbit determination matters for operations
Orbit determination underpins every operational decision that depends on knowing where an object is now and where it will be in the next minutes, hours, and days.
Higher-quality orbit estimates reduce uncertainty in conjunction assessments, improve maneuver timing and fuel efficiency, support reliable tasking and rendezvous, and help operators maintain control of large fleets while meeting coordination and sustainability expectations.
In congested LEO, robust orbit determination is also essential for rapidly characterizing newly observed objects, updating catalogs, and limiting false alarms that can overload operational teams.
How Look Up supports orbit determination
Look Up supports orbit determination by detecting and tracking objects with SORASYS radars and combining these observations with external data sources.
SYNAPSE fuses multi-source measurements, maintains object catalogues and ID cards, and delivers timely alerts and collision avoidance support, including maneuver recommendations aligned with mission constraints.
For security-sensitive users, SYNAPSE can be deployed on-premises to keep orbit determination workflows and operational decisions under controlled infrastructure while benefiting from Look Up analytics.
We deliver space situational awareness (SSA) and space domain awareness (SDA) solutions that help secure active satellites and ensure safe operations in the ever-growing expanse of space.
