Why is the life span of a LEO satellite less than that of a GEO satellite?
LEO satellites are cheaper and so they are typically not designed for as long a lifetime - they will also encounter more drag, but if that were a concern then propulsion and attitude/orbit control would … LEO costs ~\$5000/kg to place in orbit, whereas GEO is still ~\$30,000/kg.
The environment lifetime at GEO is very long, as others have stated, mostly due to the more sparse atmosphere. …

Determine orbit type from TLE
The TLE gives mean motion ($n$) in $\frac{rev}{day}$. This needs to be converted to $\frac{rad}{s}$ which can be accomplished by multiplying the $n$ TLE value by $\frac{2\pi}{86400}$.
Therefore, to …
