SOLAR SYSTEM

Detailed explanation-1: -Explanation: Spatial-division multiple access uses spatial isolation technique. Earth stations in each segment may actually use the same frequency, but because of the very narrow beam widths of the antennas, there is no interference between adjacent segments.

Detailed explanation-2: -A spot beam, in telecommunications parlance, is a satellite signal that is specially concentrated in power (i.e. sent by a high-gain antenna) so that it will cover only a limited geographic area on Earth.

Detailed explanation-3: -If the communication takes place between any two earth stations through a satellite, then it is called as satellite communication. In this communication, electromagnetic waves are used as carrier signals.

Detailed explanation-4: -Intra-satellite handover: A user might move from one spot beam of a satellite to another spot beam of the same satellite. Using special antennas, a satellite can create several spot beams within its footprint.

Detailed explanation-5: -What type of satellite TV service uses compressed data transmission to beam signals directly to every home? Explanation: The direct broadcast satellite (DBS) system is an all-digital system. Data compression techniques are used to reduce the data rate in order to produce high-quality picture and sound.

Detailed explanation-6: -Global Beam: A satellite beam with wide geographic coverage of 40 percent of the Earth’s surface, as seen from the satellite. Hemi Beam: A satellite beam with approximately half the geographic coverage of a global beam. Hertz: A measurement of satellite capacity based on cycles per second. IDU: Indoor Unit.
