Satellites are objects that orbit around planets. There are natural satellites like the Moon, and artificial satellites created by humans. The first artificial satellite was Sputnik 1, launched by the Soviet Union in 1957. Now there are over 2000 satellites orbiting Earth that provide communication signals, take photos from space, and help determine locations. While satellites offer fast connectivity even in rural areas and can share vast amounts of data, they are also expensive to launch and maintain, have limited data plans, and cannot reach some remote locations.

SATELLITE COMMUNICATION 🛰️.pptx
Satellite communication uses satellites orbiting Earth to transmit signals for telephones, radio, television, and the internet. A satellite receives a signal from an uplink station on Earth, amplifies and changes the frequency of the signal, and transmits it back to equipment on Earth. There are different types of satellite orbits including geostationary, low Earth, and medium Earth orbits. Satellites are used for applications like telephone calls, television, radio broadcasting, internet access, GPS, weather forecasting, and more. Future developments may include smaller satellites, greater use of AI, and transmission at super high and extremely high frequencies.

Introduction to satellite communication
Satellite communication allows people to communicate across long distances. Arthur C. Clarke first proposed the idea of communication satellites in 1945. The first satellite launched was Sputnik 1 by Russia in 1957, though it did not have communication capabilities. Commercial satellite communication began with the launch of Early Bird in 1965. Satellites can be in low, medium or geostationary orbits and operate in different frequency bands like C-band and Ku-band. They provide advantages like global coverage and reliability over terrestrial networks.
satellite communications introduction
This document discusses the key aspects of satellites including what they are, why they are important, their components and different types of orbits. It begins by defining satellites as objects that orbit larger bodies in space, either naturally like the Moon around Earth, or man-made. Satellites are important as they allow signals like TV and phone calls to be transmitted across long distances and areas via relaying signals. The main components of satellites are antennas and power sources. The document then describes the first satellites launched by the Soviet Union and United States and India's space program. It outlines the different types of satellite orbits and concludes with various applications and advantages and disadvantages of satellite communication.
2.5 rockets and satellites
Rockets use Newton's third law of motion to lift satellites into orbit. As the rocket exhaust is ejected downward, an equal and opposite force pushes the rocket upward. If the upward thrust is greater than gravity, the rocket will accelerate. Multistage rockets drop off empty containers as new stages ignite to continue the journey. Once in orbit, satellites require no fuel as they continuously fall toward Earth but their inertia keeps them moving horizontally, falling but never hitting the ground.

lec-gps (2).ppt
GPS has revolutionized navigation by providing an accurate global positioning system accessible to all. It quietly solved the centuries-old problem of determining location at sea or on land. GPS works by precise timing signals from 24 satellites in orbit, which allow receivers to calculate their position by comparing arrival times. This overcame historic issues like navigating without landmarks at sea and inaccuracies accumulating over long journeys. GPS receivers are now inexpensive and provide location within meters, even synchronizing clocks worldwide. This ubiquitous technology was preceded by heroic efforts to solve longitude through celestial navigation and mechanical clocks, culminating in John Harrison's chronometers that enabled the first practical global navigation system.

Satellite communication systems use satellites as relay stations to transmit radio and television signals between two points on Earth that are too far apart for direct terrestrial communication. A communication satellite receives signals on the uplink frequency from an Earth station and retransmits them on the downlink frequency to another Earth station. Satellites orbit Earth in different types of orbits depending on their altitude - geostationary orbit (GEO), low Earth orbit (LEO), and medium Earth orbit (MEO). Kepler's laws and Newton's laws of motion and gravitation explain how satellites can maintain stable orbits around Earth.
12.3 space exploration
Telescopes and space-based observation tools allow humans to observe and study objects in space. Telescopes use lenses and mirrors to collect electromagnetic radiation and produce magnified images. The largest optical telescopes are in Hawaii, with an even larger one currently under construction. Space-based tools like satellites, probes, and rovers have been launched to observe space without atmospheric interference and visit other celestial bodies. The Voyager probes left our solar system, carrying messages about humanity. The International Space Station is an orbiting laboratory built from parts delivered by shuttles and rockets.

Characteristics of satellite systems include different orbital heights, weights, coverage footprints, and latencies depending on the type of satellite and orbit.
Satellites and spacecrafts
This document discusses satellites and spacecrafts. It provides definitions of spacecraft as vehicles designed for travel outside Earth's atmosphere and satellites as spacecraft that orbit Earth or other celestial bodies. The document then covers the history of spacecraft from Sputnik being the first artificial satellite launched by the Soviet Union in 1957. It also discusses different types of manned spacecraft, spaceplanes, satellites in orbit, the services provided by satellites, types of satellites, and the role of NASA.
GPS (GLOBAL POSITIONING SYSTEM)
The GPS system uses a constellation of 31 satellites operated by the U.S. Department of Defense to provide location and timing information worldwide. Each satellite continuously transmits radio signals containing unique identifying codes, precise orbital data, and timing information. GPS receivers triangulate their position by measuring the travel time of signals from at least three satellites, determining distance through speed of light calculations. A fourth satellite measurement is needed to correct for differences between satellite and receiver clocks. The system provides navigation to both military and civilian users globally, any time, and in all weather conditions.
About satellite

CW4609 - Child Labour.pptx
Child labour refers to work performed by children under the age of 18 for long hours. Over 105 million children engaged in child labour historically. Parents often relied on child labour due to financial needs to support their families. Child labour began during the Industrial Revolution in the 1800s, when some children performed dangerous work such as in glass factories where they faced burns and heatstroke. While some children still perform light work that allows school attendance, hazardous and illegal forms of child labour like working in mines or as drug dealers remain problems due to health risks and denying children education. Efforts to address child labour focus on children's rights, supporting impoverished families, education access, and government responsibility.
Child Labour
Child labor involves the employment of young people in various industries. Historically, child labor was common in many parts of the world but faced opposition due to potential negative impacts on children's health, safety, and education. While some argue child labor provides income, others believe it prevents children from properly developing and receiving an education.

Dinosaurs
Dinosaurs lived on Earth for over 140 million years, first appearing around 230 million years ago. They came in many different types and sizes, some as big as the largest land animals and others smaller. Around 66 million years ago, a meteorite impact caused dust to block the sun's rays, removing dinosaurs' food sources and air to breathe. This likely caused the extinction of all dinosaurs except some bird dinosaurs. Fossils of dinosaurs have been discovered and studied for over 17 centuries, increasing our understanding of the prehistoric creatures. Dinosaurs continue to fascinate people through movies, toys, and other media portrayals.

It contains the largest ice sheet on Earth at 1.2 million square miles and its tallest mountain, Mount Vinson, stands at 4,892 meters. While no countries own Antarctica, increasing ice melt could raise water levels globally by 60 meters and flood coastal areas by displacing Antarctic wildlife and eliminating their sea ice habitat.

10Role of the monarch
Monarchies are countries ruled by a king, queen, or other hereditary leader. In a monarchy, leadership is passed down through families, going from the current ruler to their children or other close relatives. There are different types of monarchies that can be tribal, noble, dictatorial, religious, constitutional, or bureaucratic based on how the ruler attains and maintains power. Some key aspects of monarchies are that the monarch acts as the head of state and represents the country, though they may only hold nominal or ceremonial power instead of absolute rule, depending on the type of monarchy.
Elections.pptx
Elections are a group decision-making process that began in the 17th century where citizens in democratic countries choose people to hold public office through voting. Voters must be 18 years or older, citizens, and know how to vote. Candidates campaign and are nominated, then voters registered in that area go to polling places on election day and follow instructions to cast ballots that are counted to determine the winner with the most votes. While elections allow citizen participation and opportunities for leadership, some criticize that some votes do not matter or feel unfair.

Food Safety
This document discusses food safety. Food poisoning can occur when germs enter the human or animal body through food. Food safety aims to prevent this by ensuring germs and other contaminants like chemicals, bugs or metal fragments are not in food. Those most at risk for food poisoning are pregnant women, young children, the elderly and sick individuals. To promote food safety, it is important to prevent germs from entering food through practices like proper cooking, storage, cleaning, and handwashing and using safe water and materials. Some countries and laws focus on regulating food standards and safety.
