Communication is the lifeline that connects the satellite with the ground. The ground station that receives radio waves from INVADER is set up at Tama Art University. In order to establish wireless communication that is elemental for sending commands from the ground to the satellite, or transmitting data from the satellite down to the ground, ARTSAT team developed and implemented a flexible client-server web-based ground station system as an open-source software (https://github.com/ARTSAT/ground_station).
