Space-based sensor
Definition of space-based sensors
A space-based sensor refers to a type of sensor equipment that is deployed on artificial satellites orbiting the Earth or other celestial bodies.
These sensors are integral components of satellites and other spacecraft, and they are designed to collect data across various spectrums, including but not limited to optical, infrared, radar, and other electromagnetic spectrums.
Space-based sensors play a crucial role in a wide range of applications such as Earth observation, weather monitoring, environmental studies, military reconnaissance, and astronomical observations.
They are specifically built to withstand the harsh conditions of space, including extreme temperatures, radiation, and the vacuum environment.
By being placed in orbit, space-based sensors have the advantage of a broad field of view and the ability to collect data continuously without the interference that ground-based sensors might face from atmospheric conditions.
Role in space situational awareness and traffic management
Space-based sensors are a key input to space situational awareness and space traffic management because they can observe objects and events from above the atmosphere, improving coverage and timeliness for detecting launches, breakups, close approaches, and unusual on-orbit behaviour.
In operations, their measurements help reduce uncertainty in orbit determination and object characterization, which directly affects conjunction screening quality, maneuver planning, and post-maneuver verification.
They also add resilience to monitoring architectures by complementing ground systems, but they require robust tasking, calibration, and data fusion to turn raw observations into actionable alerts and decisions.
Operational data fusion with SYNAPSE and SORASYS
Look Up fuses space-based sensor data with ground-based observations in SYNAPSE to catalogue objects, update orbital states, and deliver alerts and risk analytics via API or interface, including secure on-premises deployment when needed.
SORASYS radars complement space-based sensors by detecting and tracking LEO objects with high reactivity to strengthen the operational space picture when atmospheric, geometry, or timing constraints limit other sources.
Together, SYNAPSE and SORASYS help operators and institutions predict conjunctions, detect orbital manoeuvres, and coordinate collision avoidance with tailored recommendations aligned to mission constraints.
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.
