Comparative Study on Various Modulation and Coding Techniques Relevant to Bangabandhu Satellite-2

Abstract

Bangladesh's dream project is the Bangabandhu Satellite 1. Bangladesh Telecommunication Regulatory Commission (BTRC) is implementing the project in collaboration with Space Partnership International, LLC of the United States. This satellite's primary goal is to ensure that telecommunications and internet services in remote areas run smoothly. However, the biggest issue with this benefit is recouping the amount of money that our country has loaned. Because the HSBC bank has loaned roughly $188.7 million. The financing would be extended again if we want to launch Bangabandhu Satellite 2 in 5 years using the same approach. As a result, we must consider how to gain a positive business and technical outcome from this. We may easily employ Bangabandhu Satellite 2 as a good potential for our satellite communication by using private TV channels and lending transponders to other countries sensibly. For the communication window, the modulation and coding technique should be as smooth as feasible. These aspects should be careful because it will be a hybrid satellite. Ground station scheduling is also a challenge for communication. We can dream of launching another satellite in 15 years if we can ensure both the technical and financial aspects of the Bangabandhu satellite. Because, in this technological age, having three satellites floating above our heads without incurring debt is a significant achievement for a developing country like ours. As a result, the theoretical focus of our analysis is on how we might achieve the milestone by examining the aspect of Bangabandhu Satellite 2.
