Correction: The accuracy is to 927.662 metres. You are a magnitude off.Fun Fact: VT-BAM has a longitutional accuracy of 92,7662037 metres at the equator. Tell me if I'm wrong but
40075 is earth's circumference in the equator.
40075/12 because 12 panels in the longitutes
and then (40075/12)/3600 because each panel is 3600x3600.
