LAPAN A5 Satellite Maps - Potential Disasters in Indonesia

The head of the National Agency of Aeronautics and Space (LAPAN), Thomas Djamaluddin, said that his party is currently developing the A5 satellite for potential disaster mapping needs in Indonesia.

Thomas said that currently his staff is working with a commercial entity to build an A5 satellite. If it goes as planned, the A5 satellite will be launched in 2022.

"The need for disaster satellites has been urgent, so far we only rely on commercial satellites to send data of potential disaster," said Thomas after Depok's national seminar on remote sensing. West Java, Wednesday, July 17th.


This low-orbit communications satellite will be equipped with a constellation of nine satellites capable of transmitting satellite data to a monitoring center on Earth.

He further explained that this satellite would be used later with ministries, institutions and the private sector, to which policy makers in the region would have access. Later, in case of a potential disaster, the police and the local government can quickly alert the community.

"The target data communication aspect can be faster and more efficient, for example buoy data developed by BPPT can be sent by the satellites to the center, so in the event of a potential tsunami, the data can be analyzed quickly. and issued quickly, "he added.

For the development process, Thomas said he collaborated with the Surabaya Institute of Technology (ITS) and Chiba University, Japan.

The technology developed for the LAPAN A5 satellite is a mickrosatelit based on a synthetic aperture radar (SAR) in the form of a radar used to draw objects in two or three dimensions, such as landscapes.

The SAR has a frequency of 1.40 Giga with wavelengths produced 1 cm to 1 meter higher than the water droplets in the clouds. With this capability, Thomas said the LAPAN A5 satellite can monitor every hour in every region of Indonesia.

"Regions will be able to access future use with ministries, institutions and the private sector, plan will be launched one-on-one with the private sector to collect data on disasters and early warning throughout Indonesia" , did he declare.
