[e2e] Satellite networks latency and data corruption

[alok]

Hi,

Is there any standard and are there any figures available on:

a. latency in satellite based networks and losses associated?
b. error correction techniques used (those which are used on a hop by 
hop bases, if any)
c. a general measurement of latency in the absence of hop by hop error 
correction techniques (assuming zero message corruption).

Is the general deployment on satellite based networks based on hop by 
hop error correction techniques?

-thanks
