How many km high are satellites?
The majority of satellites orbiting the Earth do so at altitudes between 160 and 2,000 kilometers.
How do you calculate the swath of a satellite?
For the satellite problem above, what is the maximum swath width that can be viewed by the satellite? D = (2 x 500 x 6378)1/2 = 2525 km, so the swath is about equal to the maximum area of the Earth that can be viewed from horizon to horizon at the altitude of the satellite.
How many satellite operators are there?
Space is Open for Business As highlighted in the chart above, The Union of Concerned Scientists (UCS), determined that 2,666 operational satellites circled the globe in April of 2020.

How fast does a satellite travel?
around 17,000 miles per hour
They complete an orbit in about 90 minutes because they are close to the Earth and gravity causes them to move very quickly at around 17,000 miles per hour. Many satellites need to be used for communication relay because the area they cover on Earth’s surface is small and they are moving so quickly.
What is swath of a satellite?
As a satellite revolves around the Earth, the sensor “sees” a certain portion of the Earth’s surface. The area imaged on the surface, is referred to as the swath.
How wide is a swath?
The swathe width depends on the blade length, the nature of the crop and the mower but is usually about 1.5 metres wide. Mowing may be done by a team of mowers, usually starting at the edges of a meadow then proceeding clockwise leaving a series of staggered swathes and finishing in the middle.
