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

Figure 16

A map of magnetic field declination produced from historical data available at the National Centers for Environmental Information under NOAA. The yellow isogonic line indicates a shift in magnetic declination. Blue lines indicate western declination, and red lines indicate eastern declination. Whenever DTUsat-2 is west of the yellow line over Europe, we have observed lesser performance. The left CAD rendering shows the attitude effect of western declination. When DTUsat-2 is east of the yellow line, we see better performance. The right CAD rendering shows the attitude effect of eastern declination. Likewise, Michael Williams, Indiana, USA, has reported lesser performance during DTUsat-2 passes east of the yellow line over the USA.
