Satellite & Space Missions

Department of Aerospace & Mechanical Engineering will invest in state-of-the-art manufacturing technology and address the issue of energy in the context of the global energy environment. The current focus is on the globalised competitiveness and increased awareness of the environment which made the manufacturing significantly different with more emphasis on competitive technologies and management approaches. The control includes outlining Communication satellites, Space Missions, Space Applications, and Space Propulsion, planning and building earth stations, Satellite Launcher Technology, repairing and introducing satellite communication.

Remote sensing satellites can provide accurate and timely information of the disaster affected areas. Since the earthquake of 2005, SUPARCO has provided satellite imagery, damage assessment reports and other information to the disaster management and mitigation agencies. The turnaround time from a disaster occurring in Pakistan to the provision of imagery is less than two days. SUPARCO has also been involved in contingency planning in collaboration with UN agencies.

Space Missions are spacecraft exploring the outer space by the use of astronomy and space technology. The Satellite Conference is entirely helpful for new research on space mission design. Just as space technology has advanced, the way we learn and work has changed dramatically in recent years. This conference combines the best research work and reference to cover the entire field, among the many features of this new approach are: Completely rewritten, updated, and expanded of Space Mission Analysis and Design, the most widely used text and reference in astronautics, covering a many topics. Such as human spaceflights, Missions to the Moon, Missions to Mars, Space Shuttle missions, Solar System probes.

Space exploration, the investigation, by means of crewed and uncrewed spacecraft, of the reaches of the universe beyond Earth’s atmosphere and the use of the information so gained to increase knowledge of the cosmos and benefit humanity. The exploration of Mars has been an important part of the space exploration programs of the Soviet Union (later Russia), the United States, Europe, Japan and India. Dozens of robotic spacecraft, including orbiters, landers, and rovers, have been launched toward Mars since the 1960s. These missions were aimed at gathering data about current conditions and answering questions about the history of Mars. The Satellite Conference offers key insights into cutting-edge applications from global experts, start-ups, and the winners of Europe's major innovation competitions for space applications.

An artificial satellite is an object that people have made and launched into orbit using rockets. There are currently over a thousand active satellites orbiting the Earth. The size, altitude and design of a satellite depend on its purpose. Satellites vary in size. Some cube satellites are as small as 10 cm. Some communication satellites are about 7 m long and have solar panels that extend another 50 m. The largest artificial satellite is the International Space Station (ISS). The main part of this is as big as a large five-bedroom house, but including solar panels, it is as large as a rugby field.

A communication satellite is a microwave repeater station in a space that is used for telecommunication, radio and television signals. A communication satellite processes the data coming from one earth station and it converts the data into another form and sends it to the second earth station. There are about 2,000 communications satellites in Earth's orbit, used by both private and government organizations.

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 centimetres to meters) 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). Satellites communication is utilized for TV, phone, radio, web, and military applications. There are more than 2,000 correspondences satellites in Earth's circle, utilized by both private and government associations

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.

A weather satellite is a type of satellite that is primarily used to monitor the weather and climate of the Earth. These meteorological satellites, however, see more than clouds and cloud systems. The idea of observing weather on earth from space was first introduced in the 1940s. Weather satellites can record a variety of weather and other phenomena including clouds, cloud systems, fire, pollution effects, dust storms, sand storms, snow, ice caps, ocean currents, volcanic ash in the air, smoke and much more.

A military satellite is an artificial satellite used for a military purpose. The most common missions are intelligence gathering, navigation and military communications. The military role of space satellites has increased continuously over the past three decades. In the early 1960s, the first reconnaissance satellites were launched by the United States, and the Soviet Union followed within a few years. In addition, military communications, navigation, meteorology and other satellites were developed during this period.

Satellites are the height of modern communications technology. They provide global wide access to information by transmitting radio signals from orbit around the earth. Communication satellites are used in networks by retransmitting signals from a ground base to a large area of the earth. Unlike most terrestrial alternatives, satellite networks can be rolled out quickly and inexpensively to hundreds or thousands of locations, connecting cities or remote locations across a large landmass, where copper or fibre is cost prohibitive. Since satellite networks can be set up quickly, companies can be fast-to-market with new services.

Mobile satellite services are set to change with the imminent launch of satellite personal communication services (S–PCS), through the use of non–geostationary satellites. This new generation of satellites will be placed in low earth orbit or medium earth orbit, hence, introducing new satellite design concepts. 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.

A satellite communication consists of mainly two segments. Those are space segment and earth segment. So, accordingly there will be two types of subsystems namely, space segment subsystems and earth segment subsystems. Satellites subsystems are used for many purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and space telescopes. Space stations and human spacecraft in orbit are also satellites.

Satellite Radiance is the radiant flux emitted, reflected, transmitted or received by a given surface, per unit solid angle per unit projected area. Assimilation of satellite radiance data in limited-area, rapidly updating weather model/assimilation systems poses unique challenges compared to those for global model systems. Principal among these is the severe data restriction posed by the short data cut-off time. Also, the limited extent of the model domain reduces the spatial extent of satellite data coverage and the lower model top of regional models reduces the spectral usage of radiance data especially for infrared data. These three factors impact the quality of the feedback to the bias correction procedures, making the procedures potentially less effective.

A satellite dish is just a special kind of antenna designed to focus on a specific broadcast source. The standard dish consists of a parabolic (bowl-shaped) surface and a central feed horn. To transmit a signal, a controller sends it through the horn, and the dish focuses the signal into a relatively narrow beam.
