Satellite Systems Ict

Ict or information and communications technology or technologies is the infrastructure and components that enable modern computing.

Satellite systems ict. For example a satellite fitted with radio equipment is a communication satellite. Ict is an umbrella term that includes any communication device encompassing radio television cell phones computer and network hardware satellite systems and so on as well as the various services and appliances with them such as video conferencing and distance learning. Communication satellites send and receive data from one point on the earth to another point on the earth. Satellites surrounding the earth transmit signals to the.

Satellite communications can provide communication capabilities spanning long distances and can operate under circumstances or. A satellite navigation or satnav system is a system that uses satellites to provide autonomous geo spatial positioning. It allows small electronic receivers to determine their location longitude latitude and altitude elevation to high precision within a few centimeters to metres using time signals transmitted along a line of sight by radio from satellites. The world s first satellite sputnik was successfully lunch by the soviet union in 1957 and since then the number has increased to over 1 100 operational satellites together with over 2000 obsolete satellites.

Satellite systems this course gives an overview of specifics advantages and limitations and areas of applicability of satellite communication systems for the purposes of telephony services data transmission and location services. Describe global positioning satellite gps systems and satellite navigation global positioning satellite gps systems are used to determine the exact location of a number of modes of transport e g airplanes cars ships etc. Ict is a broad subject and the concepts are evolving. On the other hand a satellite fitted with weather measuring instruments is a weather satellite.

One of the most compelling benefits of satellite communication is the fact that the signal from satellite can cover large geographic areas. Satellites are both military and private and orbit the earth either a geo stationary they stay in a fixed. Ict information and communications technology or technologies. However whilst satellite communication could provide the needed telecoms connectivity there are a few pros and cons associated with that medium that ought to be considered.

The services provided by satellite communications are voice and video calling internet fax television and radio channels. An insight is provided into availability accuracy and service portfolio that are specific to satellite technologies.
