An example of an elliptical footprint with a reception area of Germany, Austria and Switzerland. The ellipses indicate the necessary antenna diameter for receiving in cm. The footprint of a communications satellite is the ground area that its transponders offer coverage , and determines the satellite dish diameter required to receive each ...

[13] Satellite Passes, supports world map view, augmented reality view, satellite footprint, simulation mode and ...
Module:Location map/data/USA Tennessee is a location map definition used to overlay markers and labels on an equirectangular projection map of the U.S. state of Tennessee. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
A satellite ground track may be thought of as a path along the Earth's surface that traces the movement of an imaginary line between the satellite and the center of the Earth. In other words, the ground track is the set of points at which the satellite will pass directly overhead, or cross the zenith, in the frame of reference of a ground observer.
Metropolitan Statistical Areas are, according to the University of Tennessee Knoxville as areas "centered around counties containing a census-defined urban area with a population of 50,000 or more." [1]
In addition, the elliptical, rather than perfectly circular, satellite orbits cause the time dilation and gravitational frequency shift effects to vary with time. This eccentricity effect causes the clock rate difference between a GPS satellite and a receiver to increase or decrease depending on the altitude of the satellite.
The Johnson City Metropolitan Statistical Area, as defined by the United States Census Bureau, is an area consisting of three counties in East Tennessee, anchored by the city of Johnson City. As of the 2020 census , the MSA had a population of 207,285.
The Office of Management and Budget (OMB) has designated more than 1,000 statistical areas for the United States and Puerto Rico. [2] These statistical areas are important geographic delineations of population clusters used by the OMB, the United States Census Bureau, planning organizations, and federal, state, and local government entities.
