Value chain · CLM-0886
In plain terms
One design builds its satellite from six hundred pieces put together in orbit. The other says it needs no assembly in orbit at all. Nothing in between is recorded.
The claim as recorded
The two space-based solar power architectures in the register that state how their structure is divided disagree completely about whether in-orbit assembly is required at all: CAST's MMR-SPS divides a 2.4 GW array into 600 solar array modules launched to low Earth orbit, moved to geostationary orbit and assembled there, which is 4.0 MW per module, while CASSIOPeiA asserts the possibility of single payload deployment requiring no on-orbit assembly for a baseload system. The register holds no intermediate value between 600 modules and none.
Evidence behind this: Derived from three other claims. Tier follows the weakest input; all three are T2.
Scope and limits
THIS IS A DISAGREEMENT BETWEEN TWO STATED DESIGN CHOICES, NOT EVIDENCE THAT EITHER IS ACHIEVABLE. Neither count is demonstrated: CAST's is a design parameter in a summary table, CASSIOPeiA's is a possibility asserted in a concept paper and CLM-0661 records it alongside a separately asserted mass figure. THE CAST-AGAINST-SETV COMPARISON DOES NOT HOLD AND MUST NOT BE QUOTED FROM ANYWHERE, INCLUDING FROM ANY COPY TAKEN BEFORE 2026-09-14. It set CAST's 4 MW module against a 50 kW-class module from a Solar Electric Transfer Vehicle, which is not a solar power satellite, producing a factor of 80 between quantities that are not the same kind. The figure to discard is that factor of 80. Only architectures that state their own division may be compared here. The register holds exactly two.
What it assumes
That CAST's 600 solar array modules are the unit assembled, which Table IV lists as a count but does not describe as an assembly unit. That the two architectures are comparable in delivered scale - CAST states 1 GW to grid and CASSIOPeiA is quoted at 2 GW AC elsewhere, so they are within a factor of two and not identical.
Where it comes from
This is the project's own working, shown in full:
CLM-0692, from SRC-169 Table IV read from a rendered page image: array output approximately 2.4 GW, 600 solar array modules. 2.4e9 W / 600 = 4.0 MW per module. CLM-0687 (SRC-169 PDF p.10): modules launched to LEO, then moved to GEO, "where assembly takes place". CLM-0661: CASSIOPeiA's paper asserts "the possibility of single payload deployment requiring no on-orbit assembly".
Basis: count of modules assembled in orbit
