what is Atmospheric drag in satellite communication?

 Atmospheric drag
For near-earth satellites, below about 1000 km, the effects of atmospheric drag are significant. Because the drag is greatest at the perigee, the drag acts to reduce the velocity at this point, with the result that the satellite does not reach the same apogee height on successive revolutions.
The result is that the semimajor axis and the eccentricity are both reduced. Drag does not noticeably change the other orbital parameters, including perigee height.  
In the program used for generating the orbital elements given in the NASA bulletins, a pseudo-drag term is generated, which is equal to one-half the rate of change of mean motion.  
An approximate expression for the change of major axis is

where the “0” subscripts denote values at the reference time t0, and n0 is the first derivative of the mean motion. The mean anomaly is also changed, an approximate value for the change being:

Atmospheric Losses in satellite communications

 Atmospheric Losses
Losses occur in the earth’s atmosphere as a result of energy absorption by the atmospheric gases. These losses are treated quite separately from those which result from adverse weather conditions, which of course are also atmospheric losses. To distinguish between these, the weather-related losses are referred to as atmospheric attenuation and the absorption losses simply as atmospheric absorption.
The atmospheric absorption loss varies with frequency.  
For an elevation angle of 90° at the earth-station antenna, denoting this value of absorption loss as [AA]90 decibels, then for elevation angles down to10°, an approximate formula for the absorption loss in decibels is
 

Where El is the angle of elevation. An effect known as atmospheric scintillation can also occur. This is a fading phenomenon, the fading period being several tens of seconds. It is caused by differences in the atmospheric refractive index, which in turn results in focusing and defocusing of the radio waves, which follow different ray paths through the atmosphere. It may be necessary to make an allowance for atmospheric scintillation, through the introduction of a fade margin in the link power-budget calculations.

Orbital Elements

 Orbital Elements:

• Earth-orbiting artificial satellites are defined by six orbital elements referred to as the keplerian element set.  

• Two of these, the semimajor axis a and the eccentricity e, give the shape of the ellipse.  

• A third, the mean anomaly M0, gives the position of the satellite in its orbit at a reference time known as the epoch.

•  A fourth, the argument of perigee, gives the rotation of the orbit’s perigee point relative to the orbit’s line of nodes in the earth’s equatorial plane.  

• The remaining two elements, the inclination i and the right ascension of the ascending node, relate the orbital plane’s position to the earth

Apogee and Perigee Heights:

• The length of the radius vectors at apogee and perigee can be obtained from the geometry of the ellipse: 

• In order to find the apogee and perigee heights, the radius of the earth must be subtracted from the radii lengths, as shown in the following example.
