Each dot is one product. Shape encodes technology (see the "i" button next to the Technology selector for definitions). Color encodes sourcing region. Border thickness encodes how many independent sources verify the row: hairline = 1, medium = 2, heavy = 3+.

• datasheet — vendor datasheet URL was directly verified at scrape time.
• FCC brand — manufacturer holds at least one FCC grantee code (US-marketed RF gear).
• FCC equipment — a specific FCC ID was matched, with grant-level frequency band & output power.
• FAA DOC — manufacturer has an accepted FAA UAS Declaration of Compliance (Part 89 Remote ID or Part 107 OOP).

Confidence tier in the detail panel (same field as the open dataset): Tier 0 Anchor = complete provenance, direct observation; Tier 1 Verified = complete provenance from an authoritative government source (FAA DoC, FCC grant, DCMA list); Tier 2 Triangulated = multiple corroborating sources; Tier 3 Inferred = single-source or inferred. Use the Evidence-tier filter above to restrict to any tier.

Caveat: only 86 of the 1,627 rows in this explorer have ≥ 2 independent sources. Treat single-source rows as preliminary, and weight aggregate/share statistics by tier and source health.
