Analysis of automatic identification system (AIS) data LAPAN-A2 satellite acquired by S-band receiver at Rancabungur ground station

Abstract

LAPAN A2 is an Indonesian microsatellite built by Indonesia National Institute of Aeronautics and Space (LAPAN). It carries an Automatic Identification System (AIS) receiver as one of its payloads for ship monitoring with capability to record identity and position data of ships around the world along LAPAN-A2 satellite track. AIS data recorded by this satellite is acquired through S-Band frequencies using a S-Band receiver at Rancabungur Ground Station. An analysis is needed to determine the performance of the S-Band receiver. This paper provides quantity analysis of S-Band receiver by analyzing the AIS data that was acquired by the S-Band receiver. From this study, it can be concluded that the difference in the amount of data is not significant because the elevation used is also spread evenly from the smallest to the largest in terms of satellite elevation and acquisition duration.
