Title
Modeling And Simulation Of Prolate Dual-Spin Satellite Dynamics In An Inclined Elliptical Orbit: Case Study Of Palapa B2R Satellite
Abstract
In response to the interest to re-use Palapa B2R satellite nearing its End of Life (EOL) time, an idea to incline the satellite orbit in order to cover a new region has emerged in the recent years. As a prolate dual-spin vehicle, Palapa B2R has to be stabilized against its internal energy dissipation effect. This work is focused on analyzing the dynamics of the reusable satellite in its inclined orbit. The study discusses in particular the stability of the prolate dual-spin satellite under the effect of perturbed field of gravitation due to the inclination of its elliptical orbit. Palapa B2R physical data was substituted into the dual-spin's equation of motion. The coefficient of zonal harmonics J2 was induced into the gravity-gradient moment term that affects the satellite attitude. The satellite's motion and attitude were then simulated in the perturbed gravitational field by J2, with the variation of orbit's eccentricity and inclination. The analysis of the satellite dynamics and its stability was conducted for designing a control system for the vehicle in its new inclined orbit. Keywords—dual spin, prolate dual-spin, satellite dynamics, simulation Abstrak— Sebagai reaksi atas adanya minat dari beberapa pihak untuk mengoperasikan kembali satelit Palapa B2R yang mendekati masa akhir operasinya (End of Life), suatu ide untuk menginklinasi orbit satelit telah mengemuka pada beberapa tahun terakhir. Sebagai sebuah wahana dual-spin prolate, Palapa B2R harus distabilkan terhadap efek disipasi energi internal. Paper ini berkonsentrasi pada analisis dinamik dari satelit pada orbit barunya yang terinklinasi. Studi yang dilakukan mendiskusikan secara khusus kestabilan dari satelit dual-spin prolate dalam pengaruh efek dari medan gravitasi terganggu akibat inklinasi dari orbit eliptiknya. Data fisik Palapa B2R disubstitusikan ke dalam persamaan gerak dual-spin. Koefisien harmonik zonal J2 diinduksikan ke persamaan momen gradient gravitasi yang mempengaruhi sikap satelit. Gerak dan sikap satelit kemudian disimulasikan dengan variasi eksentrisitas dan inklinasi orbitnya. Analisis dinamika dan kestabilan satelit dilakukan untuk keperluan perancangan sistem kendali wahana pada orbit barunya yang terinklinasi. Kata kunci—dual-spin, dual-spin prolate, dinamika satelit, simulasi
