Wether sattelit ephotos5/21/2023 The net result of this timing is that the satellite appears stationary relative to the Earth's surface, allowing them to hover continuously over one position on the surface.Įarly geostationary satellites were "spin stabilized", meaning they maintained stability by rotating and, therefore, viewed the Earth only about 10% of the time. Positioned over the equator, the satellite completes one orbit in 24 hours, meaning it orbits in sync with the Earth's rotation. Unlike polar orbiting satellite, geostationary satellites orbit at a much higher altitude of 22,236 miles (35,786 km). The first geostationary satellite was launched in 1966. Go to the Alaska Aviation Weather Unit page for images from the polar orbiting satellites and the NOAA Satellite and Information Service (NESDIS) for the the tropical regions. Limited to about six or seven images a day since, most of the time, the satellite is below the Earth's horizon and out of range of listening equipment.The path of each orbit changes due to the Earth's rotation, so no two images are from the same location.Cannot see the whole Earth's surface at any one time.The disadvantages of polar orbiting satellites: Closer to the Earth, with an orbit of about 520 miles (833 km) above the surface, thus providing much more detailed images. ![]() The advantages of polar orbiting satellites: Currently in orbit are morning and afternoon satellites passes that provide global coverage four times daily. Since the number of orbits per day is not a whole number, the orbital tracks do not repeat on a daily basis. Today, polar orbiting satellite round the Earth 14.1 times daily. TIROS was a polar orbiting satellite, meaning the satellite orbited in a latitudinal motion, which takes it over the North and South Poles. Sightings from the surface had not prepared meteorologists for the interpretation of the cloud patterns that the view from an orbiting satellite would show. TIROS showed clouds banded and clustered in unexpected ways. Named TIROS for Television Inf rared Observation Satellite, it demonstrated the advantage of mapping the Earth's cloud cover from satellite altitudes. ![]() The world's first meteorological satellite was launched from Cape Canaveral on April 1, 1960.
