Good Essay About Satellite Application Engineering

Satellite application engineering is one of the interesting fields of engineering, which deals with the study of application of the satellites located in space. There are hundreds of satellites in the space whose purpose is to observe and understand the earth. Satellites aid in predicting the changes in the pattern of the earth and forecast natural calamities, such as earthquakes, storms, hurricanes, tsunamis and many others. It is very important to maintain an up-to-date data of the satellites for a wide variety of applications as it is the basis for various studies on the changes occurring on the earth. Earth system science, navigation systems and remote sensing are major satellite applications, which help to study the planet. Earth system science is essential to gain knowledge about the modeling of various complex processes happening on the surface of the earth. It imparts knowledge on the subjects, such as geophysical fluids, atmospheric physics, oceanography and several others.
Earth system science helps to understand the topography of the oceans based on the data collected from the satellites. Remote sensing, on the other hand, is a primary technology, which aids in acquiring information about the earth. It utilizes and interprets the measurements collected from various sensors. The major sensors used for collecting information are laser, radar, optical or thermal cameras. Remote sensing helps to analyze the modeling of geophysical processes, which include water cycle, climate change and many others. The technology used in remote sensing is vital for interpreting and modeling the complex processes of the earth. It also helps to monitor the environment and update the GIS or the geographic information system. Remote sensing plays an important role in resolving security-related issues, particularly in areas located in remote areas, which are difficult to access.
The specialty of remote sensing is that it imparts knowledge on various important subjects, such as photogrammetry, geo-information, image processing and advanced remote sensing. The best example of remote sensing application is the German radar satellite, which delivers various SAR images of the earth irrespective of the weather conditions. Another important aspect of satellite application engineering is navigation system. Today’s modern world is highly dependent on the navigation systems, which offer reliable information that plays a major role in modern logistics and controlling the traffic. The navigation systems contain maps in a readable format that help to analyze the traffic. The available navigation systems, such as the GPS or global positioning system or the GALILEO system are famous for their application of accurate positioning.
GNSS or global navigation systems are also crucial as they aid in the measurement of various geodynamic processes. Such processes include the monitoring of deformation, plate motion or determination of the precise orbits of the satellites. A reliable navigation system also helps to determine several aspects of moving objects, such as velocity, position and orientation. The best aspect of the navigation system is that it helps to understand advanced and complex processing techniques and various hardware prospects of precise positioning. It is essential to possess immense knowledge on the satellite systems in addition to information about the earth in order to master in the observation of earth from the space. Adequate knowledge in subjects, such as orbit mechanics, spacecraft technology and orbit control plays an equally important role in the efficient application of satellite application engineering.
