What is propogation delay in satellite?
A propagation delay is the amount of time it takes radio waves to travel from the surface of the Earth to the satellite and then back down to the Earth. The calculation of the delay is based upon the altitude and position of the satellite systems.

Does skype offer a good quality satellite phone?
Skype phones are not satellite phones. They are phones which connect to Wi-Fi and then run the Skype program to communicate with other phones. You can use them to call satellite phones, but they do not offer satellite phones.

What do satellite engineers do?
If the company has to communicate with satellites up in space, then the engineer would be the one to help it happen. They are the ones who access the satellite and make sure that all of the information that is relayed is correct and what they are after.
Why are ground stations in continuous contact with satellite in geostationary orbit?
Since the satellite appears fixed in the sky, antennas can also stay in a fixed position to communicate with it, and don't need to be continuously guided.
