PSLV continues to be the work horse of Indian satellite launches, especially for LEO satellites.
These are the only two ground stations able to communicate with all orbits of LEO satellites.
(You will almost always be able to contact a LEO satellite, from a vehicle or elsewhere.)
LEO satellites are picking up and dropping off messages all the time.
This prolongs the operational life of a LEO satellite, as onboard battery life is prolonged.
According to Suparco, five GEO satellites and six LEO satellites will be launched in between 2011 till 2040.
This is the first optical links connection between a fixed ground station and an LEO satellite.
Many LEO satellites are needed to maintain continuous coverage over an area.
Such an orbit is also common among civilian LEO satellites, and the spaceplane's altitude was the same as that of the ISS and most other manned spacecraft.
The improved Long March 1D can launch variant of LEO satellite; the orientation of the satellite can be rotating or non-rotating.
