I. Introduction
LAPAN-A3 is a multi-mission satellite from Indonesia carrying several payloads comprising a multispectral imager, matrix camera, thermal camera, Automatic Identification System (AIS), and scientific magnetometer [1]. This microsatellite is supported by a ground station located in Rancabungur, Indonesia, equipped with a full-motion antenna and dual-band receiver to receive all the payload data from onboard. The satellite-to-ground-station data transfer occurs 3–4 times every day, acquiring up to 7 GB of data for each transmission in the X-band spectrum [2].
