Link Budget Analysis in Designing a Web-application Tool for Military X-Band Satellite Communication

Abstract

In satellite communication, Link Budget analysis is the most important part todeterminegainsand lossesof signalsfrom the transmitter to the receiver. Most importantly, it investigates system performance and optimum power which must be received at the receiverchannel. In some cases, this information could be generated, saved for past data analysis, and share with peer users which are not found in existing web tools. Thus, it is obvious to design a newLink Budget calculator with users, database, and data retrieval support. This work focuses on designingaLink Budget web tool for X-band satellite communication through literaturestudy and comparative analysis. The X-Band calculatoris designed based on HTML, PHP, Javascript, and MySQLby ensuring several security issues, andcan be accessedthrough mobile devices.This paperalso focuseson the necessary equations of Link Budget forUplink (푇푥);Satellite;Downlink (푅푥); Azimuth, Elevation,Distance analysis; andRain attenuation. Though, comparative assessments among various web tools show some fluctuations, overall outputs show satisfactory results with small% of Errors (PoE) ensuringreliability and viability of the proposed X-Band tool for practical use.
