Land Earth Station (LES) is the point on the earth’s

coordinate of a point on the surface on the earth;
expressed in angular measurement from the plane of
the equator to a line from the center of the earth to the
point of interest. Often abbreviated as Lat.
Least Squares A
technique used on data sets that attempts to find the
number that provides the ‘best fit’ to the data. It do
so by minimizing the sum of the squares of the
residuals, which are the difference between the
estimated ‘best fit’ and the data point squared. It is
carried out using an iterative process. Furthermore, it i

the relationship between expected and observed sets o
data by minimizing the sums of the squares of deviation
between observed and expected values.
