FY-4A ancillary space-environment payload including charged-particle monitoring at platform level; modelled as a component because current sensor families do not cover in-situ space-weather packages.

Included in the Atlas for completeness. This is a supporting payload carried on an Earth-observation platform rather than a primary observing instrument, so it has a catalogue record but no full profile.

Where this fits, supply chain
