Cahya Budi Muhammad, Heroe Wijanto, Antonius Darma Setiawan

TL;DR
This paper evaluates the performance of the MUSIC algorithm for estimating the direction of arrival of signals in inter-satellite links, demonstrating its speed and effectiveness in dynamic satellite conditions.
Contribution
It introduces the application of the MUSIC algorithm for satellite AoA detection using connected satellite signals, highlighting its faster processing time compared to satellite movement.
Findings
MUSIC algorithm processes AoA in under 1 second with 50-element antenna array.
Processing time is faster than satellite movement at 830 km altitude.
Simulation confirms effectiveness for azimuth angle estimation in satellite communication.
Abstract
An attitude of satellite is not always static, sometimes it moves randomly and the antenna pointing of satellite is harder to achieve line of sight communication to other satellite when it is outage by tumbling effect. In order to determine an appropriate direction of satellite antenna in inter-satellite link, this paper analyze estimation performance of the direction of arrival (DoA) using MUSIC algorithm from connected satellite signal source. It differs from optical measurement, magnetic field measurement, inertial measurement, and global positioning system (GPS) attitude determination. The proposed method is characterized by taking signal source from connected satellites, after that the main satellite processed the information to obtain connected satellites antenna direction. The simulation runs only on the direction of azimuth. The simulation result shows that MUSIC algorithm…
