1
00:00:00.000 --> 00:00:12.000
One common starting state. Nominal 500 km SSO. Twelve 4 kg 3U payloads. Generic host: 500 kg wet bus, including 20 kg fuel once; Isp 220 s.

2
00:00:12.000 --> 00:00:24.000
Twelve scheduled releases. Actual computed Gen5 host history, uniform-2 target family. Markers identify the frozen release epochs; the inertial X/Z projection preserves the numerical trajectory.

3
00:00:24.000 --> 00:00:36.000
Host manoeuvre. Point. Release. Host burns provide the departure state and direction. The launcher adds the coupled release contribution. The propagated state depends on both.

4
00:00:36.000 --> 00:00:48.000
Frozen full-state targets. Uniform synthetic 2 m/s or alternating 1/3 m/s along-track target families. All payloads and retained host are compared at t = 91800 s: 24 h after the final release.

5
00:00:48.000 --> 00:01:00.000
Coast for loading and safe release. Gen5 reserves 400 s of zero-force loading coast per payload for the declared 355 s cycle. Both architectures keep 5 s pre-release and 20 s post-release zero-force guards.

6
00:01:00.000 --> 00:01:12.000
Command flexibility and installed cost. The ideal ground-pretrimmed spring closes both target families at the 1 N and 5 N gates. Preplanned targets give no established Gen5 propellant or initial wet-mass advantage.

7
00:01:12.000 --> 00:01:24.000
Independent replay of target states. Native Orekit 13.1.6 replay and 60→30 s refinement agree within the declared numerical residuals. Numerical agreement is not physical delivery accuracy.

8
00:01:24.000 --> 00:01:36.000
Mission model and applicability. Fixed-axis J2 point masses and constant inertial force. Drag, higher gravity, attitude/plume allocation, navigation and finite exit geometry are outside this study.

9
00:01:36.000 --> 00:01:48.000
Twelve releases. One resource account. Twelve commanded releases share one coupled resource account: payloads, retained device, host burns, source energy and carrier recovery. Inspect the frozen target states and same-input policies.
