PSLV and GSLV

I just had a quick search on the Polar satellites and Geo stationary satellites. 
PSLV is used to launch satellites to Polar orbits. That means the satellite passes above or nearly above both the poles. Also, these satellites passes over a point in earth at the same local time. for eg:, the satellite passes over any point in earth at 1 P.M local time. They are usually used for earth mapping, observation and some weather data collection.
GSLV is used to launch satellites to Geo stationary orbits.  Geo stationary orbits means the satellite's orbit will be directly above the equator and will have a period or revolution equal to the period of rotation of earth. The orbit will be roughly 35,786 km above equator. They are usually used for Satellite communications, weather data collection and GPS.
