Nuri (KSLV-II) 4th launch — secondary payload

01   The brief

One launch window, and no way to intervene after separation.

[ Draft — replace with the real brief. ] The payload had to fit a fixed mass and volume envelope, survive the launch vibration profile and the thermal-vacuum environment of orbit, and then operate autonomously.

[ Draft ] Schedule was set by the launch manifest rather than by engineering convenience, which put the qualification plan — not the design itself — on the critical path.

02   Approach

How it was built

01

Envelope lock

[ Draft ] Mass, power and volume fixed first, then the architecture built to fit inside them rather than the reverse.

02

Derated selection

[ Draft ] Every component chosen against a documented derating table, with second sources identified before layout began.

03

Qualification

[ Draft ] Vibration, thermal vacuum and EMC run against a written plan, with the report package delivered alongside the unit.

04

Integration

[ Draft ] Ground support equipment and engineers on site through payload integration and launch-site checkout.

03   Result

It passed qualification, and it flew.

[ Draft — replace with the verified outcome, including anything you are cleared to state about on-orbit performance. ]
