Design and analysis of satellite’s ground station / Yiap Joo Zheng
Reka bentuk dan analisis stesen bumi satelit merupakan satu tesis project yang menumpu pada pembinaan stesen bumi untuk satelit LEO, MYSat, yang dipersedia oleh USM Makmal Sistem Angkasa (USSL). Stesen bumi terdiri daripada pengawal azimut dan aras tinggi, pengawal stesen nod (TNC), penguatkuasa dan pra-penguatkuasa, mesin pemutar, reka bentuk, antara muka mesin pemutar-komputer serta sepasang antena VHF dan UHF yang beroperasi dengan dwi-frequensi setinggi 145.8 MHz dan 437.45 MHz. Projek ini mengkaji tentang reka bentuk dan penghasilan antara muka mesin pemutar-komputer, reka bentuk antena-antena dengan pemegang, serta reka bentuk stesen bumi yang memberikan pembayangan tentang penggabungan antara perisian dan perkakasan. Antara muka pemutar-komputer merupakan sistem yang terbuka dimiliki oleh syarikat Yaesu. Satu antara muka yang beroperasi dengan kegunaan Arduino Mega telah direka bentuk serta dihasilkan dalam projek ini. Kaedah ini memudahkan penyambungan antara komputer dan antara muka tersebut melalui bas bersiri semesta (USB). Kod akan dimuat naik dalam antara muka/Arduino merupakan kod yang bersesuian dengan GS232 dan membenarkan perisian menjejak dan mengesan satelit untuk mengawal pemutar azimut dan aras tinggi. Antena telah direka bentuk dan prestasinya telah ditiruan dengan penggunaan kod elektromagnet berangka (NEC). Akhir sekali, stesen bumi yang lengkap telah direka bentuk untuk memberikan bayangan atas penggabungan antara perisian dan perkakasan, termasuk talian penghantaran antena. _______________________________________________________________________________________________________ Design and Analysis of Satellite’s Ground Station is a thesis project based on the development of the ground station for LEO satellite, MYSat, which is going to be launched by USM Space System Lab (USSL) in near future. The ground station consists of azimuth & elevation controller, terminal nodes controller (TNC), amplifier and pre-amplifier, rotator, a fabricated rotator-computer interface and VHF & UHF antennas that operated at dual frequencies which are 145.8 MHz and 437.45 MHz. This study investigated on the design and fabricated of rotator-computer interface, design of antennas with its supporting holder and design of ground station that includes visually integration between software and hardware. Rotator-computer interface is origin from Yaesu and is an open source device. An interface operated by Arduino Mega was designed and fabricated in this study, which allows the connection to computer simply through USB port. Coding is uploaded to the interface/Arduino that is compatible with GS232 command and allow the satellite tracking software to control both the azimuth and elevation rotators. The antenna was designed, and its performance was optimized and simulated using numerical electromagnetic code (NEC). At the end of the study, a complete ground station was designed to give vision on the integration between software and hardware, including the transmission lines used.
