PassPatch

PassPatch is a web app (with optional desktop wrapper) for generating accurate, shareable coverage maps for satellites and constellations without needing a GIS team. Users upload TLEs/ephemeris, define sensors (beamwidth, min elevation, swath, duty cycle), and instantly see time-windowed coverage, revisit, and gap maps over any AOI. It outputs clean artifacts decision-makers actually use: PNG/PDF maps, GeoJSON layers, and a simple “coverage report” with assumptions clearly stated. It’s not trying to be a full mission analysis suite; it focuses on fast, defensible coverage visuals for proposals, ops planning, and customer reporting. An AI assistant helps translate plain-English requirements (“cover Kenya daily at 10am local”) into parameters, but all results remain deterministic and auditable. Pricing targets small teams who can’t justify STK licenses or custom tooling.
