Some satellites exist to monitor electromagnetic signals from the ground or other spacecraft. Orbital mechanics has things to say about why certain orbit regimes suit this mission — and we can teach that without revealing operational specifics.

SIGINT satellites detect, collect, and characterize radio frequency emissions from the ground — communications, radar signals, telemetry, and other electronic emissions.
Space-Track and commercial catalogs contain orbital elements for most SIGINT satellites.
When analysing satellites in sensitive mission categories, specific language discipline applies.
Understanding that SIGINT satellites exist and how orbital geometry serves their mission is legitimate educational content. Specific collection activities are beyond what public tracking data can support.
