In plain terms

A 2024 Chinese satellite design concept plans to beam down microwaves twice as strong as CASSIOPeiA's own typical figure, and its designers do not appear to have considered the upper-atmosphere stability question at all.

The claim as recorded

A 2024 Chinese Academy of Space Technology concept (Modular Multirotary Joints SPS) models a peak ground power density of about 460 W/m2 at 5.8 GHz for a 1 GW-class system with a 10.5km x 100m transmit array from GEO, with first and second sidelobes at 22 and 7.5 W/m2, and does not mention the ionosphere anywhere in the paper.

Scope and limits

A simulated design concept, not a flown or independently reviewed system; the absence of ionospheric discussion could reflect the paper's own scope choice rather than a considered judgement that the constraint does not bind.

What it assumes

No assumptions are recorded against this claim.

Where it comes from

SRC-169 Modular Multirotary Joints SPS Concept - Challenges and Design Considerations. IEEE...
PDF p8: with 5 m x 5 m elements, M = 2000 and N = 20, the simulated ground distribution (Fig. 9) has a main lobe of about 30 km x 300 m with the highest power density about 460 W/m2 and first and second sidelobes of about 22 and 7.5 W/m2 (sentence read verbatim at VER-716); 1 GW class at PDF p5, GEO at PDF p6; "ionosph" returns zero occurrences over all 14 pages.

Basis: W/m2, simulated peak ground beam intensity, 5.8 GHz, 1 GW-class system
