Framework

What it covers

What the capability covers and what it leaves to others, and the indicators it will be measured by.

Bounds

Covers spacecraft technology and manufacture; the spacecraft on orbit register as Strategic Infrastructure's assets, their services and defence as National Security's capabilities, and constellation economics with the economic domains.

Lineage

Relocated in v0.1 from the split group (formerly Small satellites) at the same level, carrying its identifier; recast from an asset class, one size of spacecraft, to the spacecraft technology capacity, with size classes registering at the indicator layer.

Indicators

  • satellites manufactured per yearPending
  • constellations operatedPending
  • satellite export ordersPending
