Satellite & remote sensing
A pass is a fact about light, not about output. The desk reads it as a coarse proxy with a stated mechanism, never as a number.
Whether a site is being worked, and whether high-temperature process equipment is running, at coarse resolution and with a known revisit gap.
Output, throughput, or which specific line is running. Cloud cover creates gaps, not zeros — an absence of a pass is not an absence of activity.
What decision-relevant condition can satellite evidence establish before a published report catches up?
- Observe
- Site activity index: Whether a site is being worked, at coarse resolution.
- Boundary
- continuity — cloud cover and revisit gaps
- Breaks the read
- A source receipt that cannot reproduce the observation, or a result that conflicts with this family’s stated boundary, is held rather than promoted into a desk conclusion.
No matching illustrated investigation is currently packaged for this record. The method remains open; a reporting card appears only when a durable article exists.
The same coordinates, pass over pass, so the comparison is honest.
A cloud gap and a real change in activity look identical until checked.
A grid, hiring, or procurement reading over the same period.
The next clear pass that would contradict the read.
- Persistent cloud cover over the site of interest
- Sites without a usable revisit cadence
- Activity that produces no optical or thermal signature
