[e2e] Satellite networks latency and data corruption

[Jon Crowcroft]

geo is easy to compute from the eqn in Arthur C Clarke's paper on
comsats in Wireless World in 1945

See for example
http://lakdiva.org/clarke/1945ww/

a typical british invention/discovery (like steam engines, dna, the
genome, jet engines) that was more succewfully exploited by other countries...
lucky for them we didnt patent it:)

oh, its .72 secs RTT - see for example sigcomm 88 paper on satnet 
by Seo et al

 >>Dear Alok,
 >>
 >>The link delay in a satellite network depends on whether it is a
 >>geostationary orbit (GEO) or a lower earth orbit (LEO) network. The
 >>GEO satellite link has roughly a delay of 300 ms (one way). The LEO
 >>satellite link has a one way delay that varies from [40,400] ms
 >>depending on whether the LEO network has one satellite hop or multiple
 >>hops and
 >>how far each of these satellite hops are placed.
