Upstream and downstream in space accounting

Assembled from 25 blocks · 3 evidence · 17 related

1. Story
2. The boundary decision that determines almost every headline number about the space economy. Upstream is the part that physically goes to space or builds what does: satellite manufacturing, launch vehicles, launch services, ground stations. Downstream is everything that consumes what those assets emit — direct-to-home television subscriptions, satellite broadband accounts, imagery analytics, and, overwhelmingly, the navigation and timing functions embedded in consumer devices and infrastructure. Upstream is small and visible; downstream is large and diffuse. The consequence is that measured space-economy totals are dominated by the boundary rather than by activity: count a smartphone chipset because it contains a GNSS receiver and the total swells by hundreds of billions, exclude it and the same year shrinks by a factor of several. The OECD handbook exists precisely because national statistical offices had no shared answer, and the gap between the Satellite Industry Association series, the Space Foundation series and OECD-aligned national accounts is mostly a gap between definitions, not between observations. Not a place.

22. Evidence
23. Establishes that space-economy totals depend on an upstream/downstream accounting boundary that differs between published series, and that national statistical treatment of the sector is not standardised. V55 verification basis: the handbook was not retrieved in this session; the edition year is stated from author knowledge and should be confirmed.
24. The satellite industry's revenue is reported in four segments — satellite services, ground equipment, satellite manufacturing and launch services — with services and ground equipment together forming the large majority and launch a low single-digit share. V55 verification basis: this session had no network egress and no remaining WebSearch budget, so the report was not retrieved; the segment structure is stated from author knowledge and every figure derived from it is given as a magnitude rather than a number.
25. Supports the periodisation of commercial space activity and the scale of the global space economy including government spending. V55 verification basis: not retrieved in this session — egress blocked and the search budget exhausted — so no total is quoted from it in this pack.
