Communication satellites are those satellites which are being used for all sorts of communication(mobile phone, DTH or Internet facilities).
They are usually geostationary satellites (they take 24 hours for one complete revolution around the earth, they are at approx 36000 km altitude from the surface of earth). They are 3 in number, making 120 degrees with respect to each other. They have equatorial orbits.
Remote sensing satellites are being used for Defense related purposes to detect enemy planes and aircrafts. They send radio waves to earth and after being reflected by the enemy planes they are detected.
