The first weather satellite was TIROS-1, created by a team at NASA in 1960 without a single inventor. Weather satellites use radiometers with detectors for infrared, microwave, and visible light to take images from orbit. They provide data on clouds, temperatures, storms, and other weather patterns up to every 12 hours. Infrared satellites in particular help fishermen and farmers by detecting tropical cyclones and calculating surface temperatures. All weather satellites have exterior imaging devices like radiometers and often use solar panels to generate power.

Weather satellites
The weather satellite was invented by a group of scientists and engineers working for NASA, not a single person. On April 1, 2000, NOAA launched the first weather satellite, which was composed of GOES and POES satellites that provided full Earth coverage and processed collected data. Weather satellites use radiometers to scan the Earth and detect radiation to monitor weather, transmitting data to ground stations within a minute for meteorologists to track patterns and make forecasts. They can operate for 3 to 7 years in either geostationary or polar orbits.
Meteorological Satellites
Meteorology is a discipline concerned with observational earth sciences and theoretical physics. It has the task of providing an accurate knowledge of the state of the atmosphere. Before the advent of weather satellites the weathermen had been severely handicapped by having only a very limited knowledge of the state of the atmosphere at any given time. Meteorological satellites have to a large extent has enabled to overcome this deficiency.
Spacecraft
1) Spacecraft come in many types including manned spacecraft to carry astronauts, orbiter spacecraft that enter orbit around other planets or moons, atmospheric spacecraft that study planet atmospheres, lander spacecraft that touch down on surfaces, and observatory spacecraft that study targets from orbit.
2) Key spacecraft subsystems include power (solar cells and batteries), attitude and orbit control (propulsion and stabilization), telemetry for communication with Earth, antennas, and more.
3) Launch involves fitting spacecraft inside fairings, multi-stage rockets to achieve orbit and departure trajectories, and deployment of solar arrays and antennas after launch vehicle separation.

Satellite and its orbits
This document summarizes different types of satellites and orbits. It defines a satellite as a solid object that revolves around another due to gravitational forces. Satellites are either passive, simply reflecting signals, or active with onboard processing equipment. The first artificial satellite was Sputnik 1, launched in 1957. Satellites in low-Earth orbit have shorter lifespans but provide better signals, while geostationary satellites remain fixed over one position from the ground. The document also briefly discusses Kepler's laws of planetary motion and their application to Earth.
Space environment factors
The document discusses the key factors of the space environment that affect spacecraft design. It identifies six main factors: 1) radiation environment from solar winds, the Van Allen belts, and cosmic rays, 2) the vacuum environment and challenges of outgassing, cold welding and heat transfer, 3) spacecraft charging from plasma interactions, 4) the neutral environment including atomic oxygen and atmospheric drag, 5) the plasma environment formed by ionization and particles in the Van Allen belts, and 6) micrometeoroids and orbital debris impacts. Common spacecraft materials like Kevlar, aluminum and coatings are described that can withstand these harsh conditions.
satellite-communication
Satellite communication uses satellites in orbit around Earth to relay radio signals between Earth stations. There are three main types of satellite orbits - low Earth orbit (LEO), medium Earth orbit (MEO), and geosynchronous Earth orbit (GEO). Satellites have a payload that includes antennas and transponders to receive and transmit signals, and a bus that provides structure, power, and control. Common applications of satellite communication include satellite television broadcasting, internet access, telephony, and providing connectivity to remote areas.

Forecasting the weather powerpoint
This document discusses weather forecasting and understanding weather maps. It explains that weather maps show isobars which indicate wind patterns around high and low pressure systems. Closer isobars mean stronger winds. It describes features of high and low pressure systems including wind direction. Cold fronts are shown where cold air pushes warm air upwards, potentially causing rain. Mechanisms that can trigger rain include fronts, low pressure systems, hills and turbulence. Clouds alone do not guarantee rain as clouds need sufficient moisture and lifting of air to produce meaningful rainfall.
Gps
GPS is a global navigation satellite system developed by the U.S. Navy in the 1970s that provides reliable positioning, navigation, and timing services worldwide. It works by using a network of 24 satellites that transmit timing signals to receivers on Earth, which then use trilateration to calculate their precise location by measuring distances to several satellites. GPS consists of satellites in six orbital planes, ground stations to detect and correct satellite errors, and receivers ranging from $80-600 consumer devices to specialized equipment.
Satelite communication
Satellite communication uses satellites as relay stations to transmit radio and television signals between Earth stations. There are over 750 communication satellites currently in orbit. They provide wide area coverage, transmission regardless of distance, and a transmission delay of about 0.3 seconds. Common types are fixed satellites for point-to-point communication, broadcast satellites for television/radio, and mobile satellites for satellite phones. Satellites can be in low, medium or geostationary orbits depending on their purpose and coverage needs. Frequency bands like C-band, Ku-band and Ka-band are used depending on the satellite type and application.

GPS uses a constellation of 24 satellites orbiting Earth to provide location and time information to GPS receivers. The satellites circle the planet every 12 hours across multiple orbital planes inclined at 55 degrees to the equator, ensuring signals from 8-10 satellites are visible from any point on Earth. GPS receivers triangulate their position by measuring the time delay of signals from 3 or more satellites, determining distance based on the time required for signals to travel. Factors like ionosphere delays, multipath signals, and satellite geometry can introduce errors, but parallel channel receivers maintain locks on satellites to provide accuracy within 15 meters.

Gps ppt
GPS is a satellite-based navigation system consisting of 24 satellites operated by the US Department of Defense. It provides positioning anywhere in the world without subscription fees. GPS determines location by measuring the time it takes signals from satellites to reach a receiver and using that to calculate the distance to the satellites, whose locations are known. Combining distance measurements to multiple satellites triangulates the receiver's position.

Remote Sensing - by Ashwini
Remote sensing involves collecting information about an object or area without physical contact using devices like satellites and aircraft. There are two main types: passive sensing which detects natural radiation like sunlight, and active sensing which emits energy like radar. The first weather satellite, TIROS-1, was launched in 1960 and used cameras to scan wide areas, revolutionizing remote sensing. Satellites provide an extended view of Earth and allow data collection in dangerous or inaccessible places without disturbing the environment. Remote sensing is used in fields like natural resource management and agriculture.

Remote sensing involves obtaining information about an object through sensors without direct contact. It is used in meteorology to detect weather systems like clouds and storms. There are passive sensors that detect emitted or reflected radiation and active sensors that emit radiation and detect what is reflected. Remote sensing is used from both ground-based and spaceborne platforms like satellites to monitor weather patterns and conditions. Weather satellites in particular provide remotely sensed data that can be converted into meteorological measurements and used to analyze and predict weather.
Weather satellites period 3
Weather satellites can be either geostationary or polar orbiting. Geostationary satellites orbit above the equator at high altitudes and rotate with the Earth, while polar orbiting satellites circle the poles at lower altitudes. Weather satellites detect data using visible and infrared spectrums to measure cloud cover, temperatures, and weather systems to aid forecasting. Some of the first experimental satellites included Vanguard-2 and TIROS-1, though TIROS-1 was the first successful weather satellite launched by NASA.
Satellite Applications
Satellite applications can be categorized into four main types: communication satellites, navigation satellites, observation satellites, and weather satellites. Communication satellites allow for radio, television, and telephone transmissions globally. Navigation satellites like GPS use timing signals from satellites to precisely determine location. Observation satellites are used for non-military purposes like environmental monitoring and map making. Weather satellites scan Earth with instruments to form images of cloud cover, temperatures, and weather systems.
Envisat
Envisat was a large Earth observation satellite launched by the European Space Agency in 2002. It carried 10 instruments to observe the land, oceans, ice, and atmosphere. Envisat had a sun-synchronous polar orbit at an altitude of 790 km, with an orbital period of 101 minutes and a repeat cycle of 35 days. It was designed for a 5 year mission but operated for over 10 years, until contact was lost in 2012. Envisat's observations were used to study topics like atmospheric chemistry, ocean temperatures, winds, hydrology, agriculture, natural hazards, and more.

Shreyas S. Patil(Science).ppt
The theory of satellites was simple enough - shoot something out into space at the right speed and on the correct trajectory and it will stay up there, orbiting Earth, for years - if not forever. If the orbit is the right distance in space the satellite will keep pace with the rotation of the Earth.
Early in October 1957 communications stations started picking up a regular beeping noise coming from space.
The signals were coming from Russia's Sputnik 1, the world's first man-made satellite.
It was January 1958, before a Jupiter rocket successfully launched Explorer 1, the first American satellite

When air rises and expands, it cools through adiabatic processes. This cooling can cause water vapor in the air to condense into clouds and precipitate out as rain, snow, sleet or hail depending on temperature levels. Clouds are classified based on their height and physical structure into cirrus, altostratus and nimbostratus clouds that form at high, middle and low altitudes respectively.

Unequal heating of the Earth's surface causes air temperatures to change without a change in energy. This leads some parts of the Earth to be warmer or cooler than others. When warm air rises and is blocked or forced upward by cooler air, various cloud types can form through condensation. Precipitation occurs through processes like collision-coalescence in warm clouds or Bergeron process in mixed-phase clouds, forming rain, snow, sleet, hail, or freezing rain depending on temperature.
