Satellite Forensics: Analysing Sparse Beacon Data to Reveal the Fate of DTUsat-2

Figure 15

The left graph (a) shows an uneventful power-up sequence with an operational battery. Time division is 200 mSec and voltage division is 2.5 V. The right graph (b) shows a power-up sequence with only a solar cell panel as power source. The panel is rotated into the sunlight with a rate of approximately 36°/sec. Time division is 500 mSec, and voltage division is 2.5 V. Inset below both graphs are the subsequent beacon patterns recorded with the DTUsat ground station.
