A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator). [1]
A satellite whose orbital period is an integer fraction of a day (e.g., 24 hours, 12 hours, 8 hours, etc.) will follow roughly the same ground track every day. This ground track is shifted east or west depending on the longitude of the ascending node , which can vary over time due to perturbations of the orbit.

Deep Space Climate Observatory (DSCOVR; formerly known as Triana, unofficially known as GoreSat[ 3 ]) is a National Oceanic and Atmospheric Administration (NOAA) space weather, space climate, and Earth observation satellite. It was launched by SpaceX on a Falcon 9 v1.1 launch vehicle on 11 February 2015, from Cape Canaveral. [ 4 ]
GOES-17 (designated pre-launch as GOES-S) is an environmental satellite operated by the National Oceanic and Atmospheric Administration (NOAA). The satellite is second in the four-satellite GOES-R series (GOES-16, -17, - T, and - U). GOES-17 supports the Geostationary Operational Environmental Satellite (GOES) system, providing multi-spectral ...
e. GPS signals are broadcast by Global Positioning System satellites to enable satellite navigation. Receivers on or near the Earth's surface can determine location, time, and velocity using this information. The GPS satellite constellation is operated by the 2nd Space Operations Squadron (2SOPS) of Space Delta 8, United States Space Force.
It was the first satellite to capture colour images from space and acted significantly as a medium of communications. [ 1 ] After the success of TIROS-1 and ATS-3, NASA in conjunction with United States Geological Survey (USGS), progressed forward in Earth observation through a series of Landsat satellites launched throughout the 1970s and 1980s.
The first working group report of the IPCC Sixth Assessment Report – published in 2021 – assessed that the global occurrence of rapid intensification likely increased over the preceding four decades (during the period of reliable satellite data), with "medium confidence" in this change exceeding the effect of natural climate variability and thus stemming from anthropogenic climate change.
