sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)

Variables Used

Specific Attenuation due to Clouds - (Measured in Decibel) - The Specific Attenuation due to Clouds for a given probability value, it is necessary to know the statistics of the total content of liquid water contained in a column.
Total Content of Liquid Water - (Measured in Kilogram) - Total Content of Liquid Water is the value of liquid water in the column or the total content of precipitable water for a given site.
Specific Attenuation Coefficient - (Measured in Decibel per Meter per Kilogram per Cubic Meter) - Specific Attenuation Coefficient refers to the loss of signal power due to various atmospheric phenomena that affect the transmission of electromagnetic waves between a satellite and an Earth station.
Angle of Elevation - (Measured in Radian) - The angle of elevation in satellite communication refers to the vertical angle between the horizontal plane and a line connecting an Earth-based satellite dish or antenna to a satellite in space.

STEP 1: Convert Input(s) to Base Unit

Total Content of Liquid Water: 8 Kilogram --> 8 Kilogram No Conversion Required
Specific Attenuation Coefficient: 1.332 Decibel per Kilometer per Gram per Cubic Meter --> 1.332 Decibel per Meter per Kilogram per Cubic Meter (Check conversion here)
Angle of Elevation: 42 Degree --> 0.733038285837481 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_c = (L*b)/sin(∠θ_el) --> (8*1.332)/sin(0.733038285837481)

Evaluating ... ...

Rain Attenuation in Decibels

Go Rain Attenuation = Specific Attenuation*Rain Rate^Specific Attenuation Coefficient*Slant Length*Reduction Factor

Specific Attenuation in Clouds or Fogs

Go Specific Attenuation due to Clouds = (Total Content of Liquid Water*Specific Attenuation Coefficient)/sin(Angle of Elevation)

Regression of Nodes

Go Regression Node = (Mean Motion*SCOM Constant)/(Semi Major Axis^2*(1-Eccentricity^2)^2)

Earth Station Altitude

Go Earth Station Altitude = Height of Rain-Slant Length*sin(Angle of Elevation)

Rain Height

Go Height of Rain = Slant Length*sin(Angle of Elevation)+Earth Station Altitude

Distribution of Rain Attenuation

Go Distribution of Rain Attenuation = 1+((2*Horizontal Projection Length)/(pi*Diameter of Rain Cell))

Horizontal Projection of Slant Length

Go Horizontal Projection Length = Slant Length*cos(Angle of Elevation)

Effective Path Length

Go Effective Path Length = Total Attenuation/Specific Attenuation

Specific Attenuation

Go Specific Attenuation = Total Attenuation/Effective Path Length

Total Attenuation

Go Total Attenuation = Effective Path Length*Specific Attenuation

Effective Path Length using Reduction Factor

Go Effective Path Length = Slant Length*Reduction Factor

Reduction Factor using Slant Length

Go Reduction Factor = Effective Path Length/Slant Length

Slant Length

Go Slant Length = Effective Path Length/Reduction Factor

Plasma Frequency Terms of Electronic Density

Go Plasma Frequency = 9*sqrt(Electron Density)
