Technical foundations for a shared airspace intelligence model.

Different technical foundations, working inside one model for understanding the airspace.

From sensing to a shared state

Five foundations, three jobs. Sources observe, time alignment makes them comparable, and correlation relates what they saw.

  1. Sense and receiveRadio, reflected signals, images and cooperative messages each arrive as their own family of evidence.
  2. Align and qualifyEvery observation is brought to one clock and given a statement of its quality.
  3. Correlate and fuseObservations that may belong together are related, and the link back to each source is kept.

What each foundation adds, and what it cannot prove alone

A comparison in words, with no scores. The third column names the conditions that change the answer.

Technical foundations: what each adds, what it cannot prove alone, and the conditions that change it
FoundationWhat it addsWhat it cannot prove aloneConditions that change it
Passive RF SensingEvidence of emissions where nothing else is lookingWhat the emitter is, or who sent it.Terrain, buildings and the local radio environment
Passive Coherent Location (Passive Radar)Continuous watch of an area from signals already in the airA single position from one pair of transmitter and receiver.Which transmitters are present, and the paths between them
Electro-Optical & Infrared PerceptionThe class and surroundings of an object in viewAnything outside the view, in the dark or in poor weather.Light, haze, rain, glare and background
Cooperative & External Aviation DataIdentity and intent that senders choose to shareObjects that do not report, or reports that are wrong.Feed delay, completeness and local rules on who broadcasts
Time Alignment & Data QualityA common clock and a visible measure of data qualityThat an aligned observation is true.Network delay, clock drift and loss of a reference

How far to trust each page

Each foundation is described at the evidence level of the projects that implement it. A foundation that is sound on paper is still a design until it has been tested in the field.
