COTS payload screen ยท 2026-06-16

Quote COTS paths before committing to custom fabrication.

The updated F-number-aware screen shows that some fast 640-class COTS cameras can clear the 3 cm smouldering-char SNR gate at 120 m. RFS-011 now needs product evidence and quotes: raw frames, calibration state, integration burden, false-positive performance, and unit cost.

What changed

The COTS question moved from optical plausibility to product qualification.

Model gate

Benchmark single-pixel SNR ≥ 10 for a 3 cm, 430 K char at 120 m.

Budget gate

AUD 100k (~USD 66k) spread across the payloads needed for hourly revisit.

Custom reference

Current custom recurring band is USD 22k–USD 57k per payload before quotes.

Open decision

COTS can only replace custom if raw radiometry, calibration state, payload integration, and false-positive performance clear review.

The area columns show required payload count and the maximum per-payload unit cost allowed by the AUD 100k payload budget. They are quote ceilings, not vendor prices.

Before procurement

Each surviving branch still has a product-evidence gate.

Custom Boson+ survey reference

Keep as the controlled custom reference, but do not fabricate before the COTS quote gate.

Strong: detector-level raw/pre-AGC path is part of the custom requirement.

ICI 8640 P, 35 mm lens class

Quote as the strongest COTS-adjacent surrogate for focused-zone trials.

Strong: local baseline records 14-bit raw/radiometric output and SDK/USB integration.

ICI 8640 P, 25 mm lens class

Quote beside the custom reference because coverage is similar but optical risk is lower.

Strong: local baseline records 14-bit raw/radiometric output and SDK/USB integration.

Hadron 640R fixed module

Quote only if the exact radiometric/raw data path and thermal calibration hooks are acceptable.

Conditional: radiometric Boson-family core, but exact raw/pre-AGC export must be confirmed.

45 deg 640-class radiometric camera

Do not buy generically; ask vendors for raw radiometry, calibration hooks, mass, power, and quote.

Variable: Vue Pro R / XT2 / Tau / Duet-class products differ in raw access and lifecycle status.

69 deg 640-class mapping camera

Quote only as a find-only area-survey branch; reject if raw frames or calibration state are hidden.

Variable: wide fixed-lens cameras can be radiometric, but exact raw/pre-AGC access is product-specific.

Lepton 3.1R SWaP floor

Use only as an electronics and pipeline floor; reject as the RFS-011 primary payload.

Partial: radiometric output exists, but format, frame rate, and resolution are severe limits.

RFS-011 decision reading

The next stakeholder choice is COTS quote gate versus custom package ownership.

Quote COTS now

Ask vendors for raw/pre-AGC access, calibration metadata, lens F-number, mass, power, export limits, and unit pricing for the exact payload candidate.

Keep custom alive

Custom optics remain justified if RFS needs package ownership, baffling/window control, detector placement, or a narrower false-positive/localization path.

Reject Lepton as primary

The SWaP floor is useful for electronics and pipeline work but does not clear the 3 cm target gate at the reference altitude.

Do not close RFS-011 yet

The screen reduces uncertainty but still needs quotes, product data, and stakeholder agreement on target area and altitude authorisation.
