Whois & Analysis for esa.int

The European Space Agency (ESA; ASE) is an intergovernmental organisation of 22 member states, dedicated to the exploration of space.

Established in 1975 and headquartered in Paris, France, ESA has a worldwide staff of about 2,000 and an annual budget of about €5.25 billion / US$5.77 billion (2016).

Human spaceflight (also referred to as manned spaceflight) is space travel with a crew or passengers aboard the spacecraft.

Spacecraft carrying people may be operated directly, by human crew, or it may be either remotely operated from ground stations on Earth or be autonomous, able to carry out a specific mission with no human involvement.

Space exploration is the ongoing discovery and exploration of celestial structures in outer space by means of continuously evolving and growing space technology.

While the study of space is carried out mainly by astronomers with telescopes, the physical exploration of space is conducted both by unmanned robotic space probes and human spaceflight.

Telecommunication is the transmission of signs, signals, messages, writings, images and sounds or intelligence of any nature by wire, radio, optical or other electromagnetic systems.

Telecommunication occurs when the exchange of information between communication participants includes the use of technology.

It is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation.

Such transmission paths are often divided into communication channels which afford the advantages of multiplexing.

The term is often used in its plural form, telecommunications, because it involves many different technologies.

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 metres) using time signals transmitted along a line of sight by radio from satellites.

The system can be used for providing position, navigation or for tracking the position of something fitted with a receiver (satellite tracking).

The signals also allow the electronic receiver to calculate the current local time to high precision, which allows time synchronisation.

Satnav systems operate independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the positioning information generated.
