Power budget
Balance computed from measured power consumption
| Condition | Value |
|---|---|
| Start | From eclipse |
| Sunlight / eclipse | 55 min / 35 min |
| Case 1 | Scenario with the most overlapping missions |
| Case 2 | Long APRS operation, 1200 min of digipeating |
Case 1 scenario
| Pass | Activity |
|---|---|
| 1 | GMSK / Chat Bot / CIGS / bus |
| 1.5 | Cho Lab camera / Bhutan camera / bus |
| 2 | GMSK / digipeat / bus |
| 2.5 | Chibany camera / bus |
| 3 | GMSK / digipeat / bus |
| 4 | GMSK / digipeat / bus |
| 5 onward | Bus only |
In case 1 the SOC recovers to 100% after 806 min. Case 2 also meets the operating time requirement; the power budget closes in both conditions
