Abstract

Nasional Institute Aerounautics and Space (LAPAN) has two satellites (LAPAN-A2 and LAPAN-A3) that are carry Automatic Identification System (AIS) sensors. It can be use for monitoring Indonesian maritime. The altitude of the satellite about 642 Km and 500 km so it has a wide area covered and receive big data. The problem is the AIS technology use the Time Division Multiple Access (TDMA) system that has limitations in handling big data so that some data received can be damaged due to collision. Therefore, in this research has been done the analysis and correction data using interpolation and extrapolation methods. The results is improvements of valid data about 22,6 % for LAPAN-A2 satellite and 20,8 % for LAPAN-A3 satellite.

Abstract

Pada tanggal 10 Januari 2009 LAPAN telah mengoperasikan satelit LAPANTUBSAT selama dua tahun. Pada tahun kedua pengoperasian satelit ini, star sensor, salah satu sensor kendali sikap mengalami kegagalan. Beberapa prosedur dan metode baru dilakukan untuk melanjutkan misi satelit dalam pengamatan permukaan bumi. Salah satu metode yang digunakan adalah menggunakan panel surya untuk menentukan orientasi sikap satelit. Panel-panel surya tersebut terpasang pada setiap sisi satelit. Sikap satelit kemudian ditentukan berdasarkan perbandingan distribusi arus listrik dari semua panel surya. Setelah orientasi satelit diketahui, operator dapat mengendalikan satelit agar mengarah ke target. Dengan memanfaatkan cara ini, LAPAN-TUBSAT masih mampu menghasilkan data video dengan baik.
