RECORD OBSERVATORY · 2026
Optical & Satellite Communications Record Observatory
A sourced map of communication at the edge of light
From 200 Gbit/s in low Earth orbit to photon recovery across 460 million kilometres, this observatory does not force incompatible achievements into a false leaderboard. Every result is read in its own link class, distance, rate, precision and evidence context.

POWER programmeVerification rule
“Best” is used only when the evidence supports it.
An official source or technical paper must explicitly support a record or world-first claim. Otherwise, the result is classified as a public benchmark. Range, data rate, tracking precision, power, orbit class and quantum trust model are never compared without context.
- Verified record: a primary source explicitly supports the claim.
- Benchmark: the number is credible, but a universal ranking is not defensible.
- Future target: announced programme or capacity, not achieved performance.
