The fluxgate magnetometer equipment of LAPAN up to now does not have a supporting system to monitor geomagnetic anomaly in real time. For that reason it is necessary to build and develop such a system. In this system that we will develop a system, so that the analog data received by the fluxgate magnetometer (H component, D component and Z component) parallelly will be procceed to be a digital data integrated trought a card interface. This real time data monitoring system will be by the software to do data acquisition and visualization
