Slant Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Slant Length = Effective Path Length/Reduction Factor
L_slant = L_eff/r_p
This formula uses 3 Variables

Variables Used

Slant Length - (Measured in Meter) - Slant Length refers to the length of path followed by the radio wave signal as it travels from the transmitting satellite to the receiving satellite ground station.
Effective Path Length - (Measured in Meter) - Effective Path Length refers to the total distance that a radio signal travels between a transmitter and a receiver, taking into account the effects of multipath propagation.
Reduction Factor - The reduction factor represents the factor by which the effective path length is reduced compared to the straight-line distance between the observer and the satellite.

STEP 1: Convert Input(s) to Base Unit

Effective Path Length: 12 Kilometer --> 12000 Meter (Check conversion here)
Reduction Factor: 0.85 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_slant = L_eff/r_p --> 12000/0.85

Evaluating ... ...

L_slant = 14117.6470588235

STEP 3: Convert Result to Output's Unit

14117.6470588235 Meter -->14.1176470588235 Kilometer (Check conversion here)

FINAL ANSWER

14.1176470588235 ≈ 14.11765 Kilometer <-- Slant Length

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)

Slant Length Formula

Slant Length = Effective Path Length/Reduction Factor
L_slant = L_eff/r_p

Why reduction factor is used?

The strength reduction factor is used to decrease the estimated strength of structural members, i.e., to compute the design strength of concrete elements. It is used to account for uncertainties in materials, possible design, and construction errors.
