Telkom University has once again produced an innovative product namely the Over The Horizon (OTH) Rocket. The development of the innovative product was initiated by the Center for Excellence in Science and Technology of Higher Education (PUI-PT), The University Center of Excellence for Advanced Intelligent Communications (AICOMS) at Telkom University. The OTH Rocket was produced to create a security system capable of effectively and rapidly protecting areas around Indonesia.
Director of AICOMS, Dr. Eng. Khoirul Anwar, S.T., M.Eng. explained that the rocket is one of the security systems that is capable of operating with a far-reaching range that is expected to address military threats through an automated control system.
“The Republic of Indonesia has a vast territory, which includes both land and sea. To protect sovereignty over such a large area, an innovative product that can be operated remotely and quickly is needed. The OTH rocket is capable of transmitting coordinate data and multimedia such as images, videos, and sound in real-time, wirelessly.” explained Khoirul.
Technically, Khoirul explained that the research proposed a narrowband communication system for high-speed aircraft communication using Low-Density Parity-Check (LDPC) with a structure based on the second generation digital terrestrial television broadcasting system (DVB-T2) as its channel coding.
“The communication system uses single-carrier technique because it has an excellent ability on a high-speed aircraft. Over The Horizon (OTH) communication technique is also utilized to broaden radio signal range because the rocket needs to travel a great distance.” said Khorul.
This project with the output of a rocket has been started since 2019 and it is expected to be completed in 2024. The project, which is funded by National Research and Innovation Agency (BRIN), is developed by National Rocket Consortium with its members consisting of National Institute of Aeronautics and Space (LAPAN) as the program coordinator, Research and Development Agency of Ministry of Defense (Balitbang Kemhan), Indonesian Institute of Sciences (LIPI), Agency for The Assessment and Application of Technology (BPPT), Puslit Karet, PT. PINDAN, PT. DI, Dahana, PT LEN, PT INTI, Telkom University, and Indonesia Defense University.
“The expected outcome in developing the communication system for the rocket is to minimize errors and lower the error-floor that occurs in the rocket, enabling it to achieve turbo-cliff effect performance for real-time multimedia data transmission from a moving transmitter or receiver.” expected Khoirul.
