International Conference on Satellite and Space Communications November 18-19, 2019 Holiday Inn Rome Aurelia, Rome, Italy

3D printing is very useful for aerospace applications on many aspects. Indeed, it could become a major asset for space travels in the future. In aerospace many applications, challenges, innovations related to 3D printing are tuning pace at a higher rate. Step by step, researchers are looking for different applications to this cutting-edge technology in space whereas additive manufacturing is challenging and requires new technologies and resistant materials. With the two different axis of applications arises variant benefits i.e. 3D printing inside of the station and 3D printing outside of the station. Inside it will play role significantly in their daily life in orbits during space exploration, example- when something is broken, and they need to replace a part, it can be long and expensive to send them what they need so they can simply 3D Print it. It is the same thing if a tool is missing. It would be so much easier and time-saving if they could just 3D print their screwdriver when they need it! Regarding the additive technology outside of the station, A 3D printer working in orbit would allow to come up with or create satellite structures. These machines could be integrated inside Nano satellites. Nano satellites could allow to 3D print structures directly in space a

Currently Space Missions are spacecraft exploring Mercury, Mars, Venus, and Saturn, as well as a comet and an asteroid. The Voyager spacecraft are move at high speed out of our solar system, while New Horizons speeds toward a 2015 encounter with Pluto. Closer to home, we have probes in lunar orbit, a handful of solar physics missions, space telescopes, and a small army of Earth-observing satellites. In Earth orbit, the International Space Station continues to soar around the planet with a continually Space Missions staffed crew of astronauts and cosmonauts. Satellite conference covers a wide range of topics to innovative space applications while focusing on Earth observation and satellite navigation.

Satellite orbits vary greatly, depending on the purpose of the satellite, and are classified in a number of ways. Well-known (overlapping) classes include low Earth orbit, polar orbit, and geostationary orbit. A launch vehicle is a rocket that throws a satellite into orbit. Usually it lifts off from a launch pad on land. Some are launched at sea from a submarine or a mobile maritime platform, or aboard a plane see air launch to orbit .Satellites are usually semi-independent computer-controlled systems. Satellite subsystems attend many tasks, such as power generation, thermal control, telemetry, attitude control and orbit control.

A remote sensing instrument collects information about an object or phenomenon within the instantaneous -field -of-view (IFOV) of the sensor system without being in direct physical contact with it. The sensor is located on a suborbital or satellite platform. A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data.

Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Weather and forecasting is the application of science and technology to predict the state of the atmosphere for a given location. Weather forecasts are made by collecting significant data about the current state of the atmosphere at a given place and using scientific understanding of atmospheric processes to project how the atmosphere will change.

Satellite Navigation is a system of satellites that provide autonomous geo-spatial positioning with global coverage. It allows small electronic receivers to determine their location (longitude, latitude, and altitude) to high precision (within a few meters) using time signals transmitted along a line of sight by radio from satellites. The signals also allw the electronic receivers to calculate the current local time to high precision, which allows time synchronization. A Satellite Navigation system with global coverage may be termed a global navigation satellite system (GNSS).

Space weather is a branch of space physics and aeronomy concerned with the time varying conditions within the Solar System, including the solar wind, emphasizing the space surrounding the Earth, including conditions in the magnetosphere, ionosphere and thermosphere.  Space weather is distinct from the terrestrial weather of the Earth's atmosphere troposphere and stratosphere. The science of space weather is focused on fundamental research and practical applications. The term space weather was first used in the 1950s and came into common usage in the 1990s.the magnetosphere, ionosphere and thermosphere.  Space weather is distinct from the terrestrial weather of the Earth's atmosphere troposphere and stratosphere. The science of space weather is focused on fundamental research and practical applications. The term space weather was first used in the 1950s and came into common usage in the 1990s.

Aerospace engineering is the primary branch of engineering concerned with the research, design, development, construction, testing, science and technology of aircraft and spacecraft. It is divided into two major and overlapping branches: aeronautical engineering and astronautical engineering. Aerospace Engineering and Technology focusing on communications between earth communication stations and space-based communication satellites. The method involves designing Communication satellites, Space Missions, Space Applications, Space Propulsion, designing and building earth stations, Satellite Launcher Technology, repairing and installing satellite communication equipment. Aerospace Engineering deals with the design, construction, and study of the science behind the forces and physical properties of aircraft, rockets, flying craft, and spacecraft. The field also covers their aerodynamic characteristics and behaviours, air foil, control surfaces, lift, drag, and other properties.

A satellite dish is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish used by consumers to receive direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit.

Small satellites, miniaturized satellites, or smallsats, are satellites of low mass and size, usually under 500 kg (1,100 lb). While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay.

The Asteroid Impact Mission is a small ESA mission of opportunity to explore and demonstrate technologies for future missions while performing scientific examination on a binary asteroid and addressing planetary defense. Asteroids and comets are very interesting objects, being the remnants of the earliest years of the formation of our Solar System, more than four billion years ago. The word asteroid means "star-like" and these objects appear in the sky as bright, point-like stars. But, unlike stars, asteroids are rocks orbiting our Solar System: they don’t emit light on their own and are visible only because they reflect sunlight.

Electronic communication can take place in one-way or two-way transmission mode. One-way communication mode is a simple communication wherein a receiver lacks the ability to communicate back. The two-way communications may be half duplex or full duplex communication wherein a receiver can communicate with the transmitter. A Satellite communication is a technology that is used to transfer the signals from the transmitter to a receiver with the help of satellites. It can be used in different mobile applications that involve communication with the ships, vehicles and radio broadcasting services. The power and bandwidth of these satellites depend on the specifications like complexity, size and cost.

LTE (Long-Term Evolution) commonly marketed as 4G LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements. LTE is the natural upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries will mean that only multi-band phones will be able to use LTE in all countries where it is supported.

A military satellite is an artificial satellite used for a military purpose. The most common missions are intelligence gathering, navigation and military communications. The first military satellites were photographic reconnaissance missions. Some attempts were made to develop satellite based weapons but this work was halted in 1967 following the ratification of international treaties banning the deployment of weapons of mass destruction in orbit. As of 2013, there are 950 satellites of all types in Earth orbit. It is not possible to identify the exact number of these that are military satellites partly due to secrecy and partly due to dual purpose missions such as GPS satellites that serve both civilian and military purposes.

Earth system science (ESS) is the application of systems science to the Earth sciences. In particular, it considers interactions between the Earth's "sphere atmosphere, hydrosphere, cryosphere, geosphere, pedosphere, biosphere and, even, the magnetosphere as well as the impact of human societies on these components. At its broadest scale, Earth system science brings together researchers across both the natural and social sciences, from fields including ecology, economics, geology, glaciology, meteorology, oceanography, paleontology, sociology, and space science. Like the broader subject of systems science, Earth system science assumes a holistic view of the dynamic interaction between the Earth's spheres and their many constituent subsystems, the resulting organization and time evolution of these systems, and their stability or instability. Subsets of Earth system science include systems geology and systems ecology, and many aspects of Earth system science are fundamental to the subjects of physical geography and climate science.

A large number of satellites are used today to explore the earth's atmosphere, the oceans, the earth's structure and the biosphere. Satellites employ a large variety of instruments and techniques from remote sensing and inverse problems to monitor and visualize physical, chemical and biological processes taking place above, in or on the surface of our planet earth.

Earthquake defines a structure's ability to sustain its main functions, such as its safety and accessibility, at and after a particular earthquake exposure. A structure is normally considered safe if it does not endanger the lives and well-being of those in or around it by partially or completely collapsing. A structure may be considered serviceable if it is able to fulfill its operational functions for which it was designed. Basic concepts of the earthquake engineering, implemented in the major building codes, assume that a building should survive a rare, very severe earthquake by sustaining significant damage but without globally collapsing. On the other hand, it should remain operational for more frequent, but less severe seismic events.

Satellite Radiance Measure up welling radiation at top of atmosphere. Measure New IR instruments and deep layers generally implies large horizontal scale. Weather satellites do not measure temperature directly but measure radiances in various wavelength bands. Since 1978 Microwave sounding units (MSUs) on National Oceanic and Atmospheric Administration polar orbiting satellites have measured the intensity of upwelling microwave radiation from atmospheric oxygen, which is proportional to the temperature of broad vertical layers of the atmosphere.

Orbital mechanics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft. Orbital mechanics focuses on spacecraft trajectories, including orbital maneuvers, orbit plane changes, and interplanetary transfers, and is used by mission planners to predict the results of propulsive maneuvers.

Materials science is a syncretic discipline hybridizing metallurgy, ceramics, solid-state physics, and chemistry. It is the first example of a new academic discipline emerging by fusion rather than fission. The accuracy of the materials science portrayed spans a wide range – sometimes it is an extrapolation of existing technology, sometimes it is a physically realistic portrayal of a far-out technology, and sometimes it is simply a plot device that looks scientific, but has no basis in science. This is also the theme of many technical articles, such as Material By Design: Future Science or Science Fiction? found in IEEE Spectrum, the flagship magazine of Institute of Electrical and Electronics Engineers.

The main applications of satellites are mainly categorized as, Weather forecast used to observations from which to analyses the current state of the atmosphere. Broadcasting services include radio and television delivered directly to the consumer and mobile broadcasting services. Earth observation satellites are used for observing the earth's surface, possible to see many features that are not obvious from the earth's surface, or even at the altitudes at which aircraft fly. The Global Positioning System (GPS) is the first core element of the satellite navigation system widely available to civilian users.

Wireless communications are the transfer of data or power between two or more points that are not connected by an electrode. The most common wireless technologies use radio waves. Other examples of applications of radio wireless technology include garage door openers, keyboards and headsets, wireless computer mice, GPS units, headphones, radio receivers, satellite television, cordless telephones, and broadcast television.

Satellite Communications is telecommunications to use of the artificial satellites to provide the communication links between many points on Earth. It is the use of Satellite Technology in the field of Communications. Satellite Communications play a vital role in the global telecommunications system. Approximately 2,000 artificial satellites orbiting Earth relay analog and digital signals carrying voice, video, and data to and from one or many locations worldwide.

The number of mobile subscriptions has been increased over the past years. It will influence the impact on CO2 emissions of telecommunication and e-commerce system. Green communication is the selection of energy capable communications, networking technologies and products. It reduces resource to use whenever possible in all categories of communications.
