Intelligence Applications
Reconnaissance Timing
U.S. and foreign recon satellites (KH-series, Lacrosse, Yantar) follow public NORAD catalog entries. Predict their pass windows over any target to understand when overhead collection is possible.
Imagery Collection Windows
Commercial Earth observation satellites (Planet, Maxar, Sentinel-2) have predictable revisit cycles. Cross-reference pass times with known events to identify likely collection opportunities.
Signals Intelligence (SIGINT)
SIGINT satellites require line-of-sight to collect. Knowing when a satellite has your area in its footprint — and at what elevation — defines the collection window. Doppler shift data supports frequency analysis.
Denial & Deception Planning
Operational security around satellite overflight is a core military planning consideration. Pass predictions let you identify when activity at a site may be visible from orbit — and when it won't be.
Constellation Mapping
Starlink, OneWeb, and military communications constellations are visible here in real time. Pattern analysis of constellation density over a region reveals coverage gaps and surge indicators.
