RPO activity monitoring
Definition
RPO (Rendezvous and Proximity Operations) activity monitoring refers to the capability to observe, track, and analyze the activities of satellites and spacecraft conducting close-approach maneuvers to other space objects. This involves tracking the position and motion of the observed objects as they execute movements near other satellites or debris, ensuring precise data collection for space situational awareness. The monitoring activities are crucial for understanding the behaviors of various space assets, preventing potential collisions, and identifying any anomalous or potentially threatening maneuvers. RPO activity monitoring is an intelligence capability that supports space traffic management by providing critical data that informs operational decision-making and strategic assessments.
Why RPO activity monitoring matters
RPO activity monitoring matters because close-approach maneuvers compress decision timelines and increase the consequences of orbit and attitude uncertainties. It supports safer operations by detecting and characterizing approach patterns, distinguishing benign servicing or inspection from anomalous behavior, and providing evidence to coordinate responses with operators and authorities.
At constellation scale, it underpins space traffic management and space security by improving attribution, reducing collision risk during proximity events, and enabling timely protective actions.
How Look Up supports RPO activity monitoring
Look Up supports RPO activity monitoring by detecting and tracking proximity events with SORASYS radars and fusing those observations with external data in SYNAPSE to build a timely, coherent space picture. SYNAPSE helps catalogue and characterize behaviors, generate object ID cards, and issue real time alerts to support rapid operational decisions.
Together, they help operators predict risk and recommend protective actions, including collision avoidance support and tailored maneuver recommendations that account for 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.
