Introduction

In the world of satellite communication, especially for the Point to Point Very Small Aperture Terminal (VSAT) system, Link Budget calculation is an important step to ensure optimal communication performance. The Link Budget is an analysis used to determine the amount of power needed in the communication system to achieve certain goals, such as reach, signal quality, and reliability. In the context of vsat communication, the link budget considers several factors, including transmitting power, antenna gain, distance, and atmospheric influence. In this article, we will discuss the design of the calculator specifically designed to calculate the communication budget vsat vsat to point using the Java programming language.

What is the Link Budget?

The Link Budget is a critical component in the design and implementation of VSAT systems. It is an analysis used to determine the amount of power needed in the communication system to achieve certain goals, such as reach, signal quality, and reliability. The link budget considers several factors, including:

Transmitting power: The amount of power transmitted by the VSAT terminal.
Antenna gain: The gain of the antenna used to transmit and receive signals.
Distance: The distance between the VSAT terminal and the satellite.
Atmospheric influence: The effects of the atmosphere on the signal, such as attenuation and scattering.

Main Components in Budget Link Calculator

Calculators designed in this thesis rely on several major parameters to do calculations, including:

Up-link Parameter

The up-link parameter includes:

Transmitting power: The amount of power transmitted by the VSAT terminal.
Transmitter antenna gain: The gain of the antenna used to transmit signals.
Losses: The losses that may occur during the transmission, such as cable losses and connector losses.

Down-link Parameter

The down-link parameter focuses on signal reception, including:

Gain antenna receiving: The gain of the antenna used to receive signals.
Receipt loss: The losses that may occur during the reception, such as cable losses and connector losses.

C/N Parameter (Carrier-to-Noise Ratio)

The C/N parameter is a ratio between signal power and noise power in the system. This calculator will count C/N for up-link, down-link, and total C/N.

Implementation and Testing

By using Java as a programming language, this calculator is designed to calculate relevant values easily. Users can enter the parameter values needed based on C-Band standards, which are general standards in vsat communication. After the parameters are entered, the calculator will automatically calculate C/N Up-Link, C/N Down-Link, and C/N Total.

Testing conducted on the calculator shows that the resulting calculation results are more efficient than manual calculations. The advantages of using this calculator include:

Speed: Reducing the time needed to do the calculation.
Accuracy: Minimizing human errors that often occur in manual calculations.
Ease of access: Users who are not accustomed to technical calculations can easily use this calculator.

Conclusion

The design of the calculator to calculate the vsat point to point communication budget link not only increases efficiency in the calculation process, but also provides accessibility for various groups, ranging from technicians to students. With the results of testing that shows good performance, this calculator is expected to be a useful tool in the satellite communication industry, especially in the design and implementation of the vsat system. Through advances in technology and appropriate design, we can better utilize the potential of satellite communication for the future.
