Abstract

Lapan-A4 is Indonesian fourth’s microsatellite after successfully launch of LAPAN-3/ LAPAN-IPB on June 2016 which is currently in 2 years operational. Continuing the previous mission, all activities such design, assembly, integration, and test are fully carried out in Indonesia. The main mission of LAPAN-A4 is an earth observation using multispectral imager and support global maritime traffic monitoring using space-based Automatic Identification System (AIS) receiver. The other missions are scientific research using space-based magnetometer and experimental thermal infrared sensor. The multispectral imager consists of four bands (R, G, B, and NIR) medium resolution and high resolution. The space-based AIS receiver is more advance compare with the AIS receiver that has been flown in LAPANA2/LAPAN-ORARI and LAPAN-A3/LAPAN-IPB. These two missions will complement previous missions of LAPAN-A2/LAPAN-ORARI and LAPAN-A3/LAPAN-IPB. Supporting these missions, several aspects of design has been defined, considered, and analyzed include the payload system, bus and electronics system, and structure. LAPAN-A4 plans to launch in the 1st quarter of 2020.

LAPAN-A4地球观测和海上监测任务的概念和设计

在2016年6月成功发射LAPAN-3/ LAPAN-IPB之后，Lapan-A4是印度尼西亚的第四颗微型卫星，目前已经运行了2年。继续之前的任务，所有的活动，如设计、组装、集成和测试都在印度尼西亚完全进行。LAPAN-A4的主要任务是使用多光谱成像仪进行地球观测，并使用天基自动识别系统(AIS)接收机支持全球海上交通监测。其他任务是利用天基磁力计和实验性热红外传感器进行科学研究。多光谱成像仪分为R、G、B、近红外四个波段，中分辨率和高分辨率。天基AIS接收机相对于已经飞行的LAPANA2/LAPAN-ORARI和LAPAN-A3/LAPAN-IPB具有更大的先进性。这两个特派团将补充以前的拉潘- a2 /拉潘- orari和拉潘- a3 /拉潘- ipb特派团。为了支持这些任务，已经定义、考虑和分析了设计的几个方面，包括有效载荷系统、总线和电子系统以及结构。LAPAN-A4计划于2020年第一季度推出。
