[FONT=Arial CE,sans-serif]The Project[/FONT]
[FONT=Arial CE,sans-serif][SIZE=-1]The MAROC-TUBSAT project is a cooperation between CRTS Morocco and the Institut für Luft-und Raumfahrttechnik in Berlin, where the Moroccan side is responsible for payload and launch and the German side for the satellite bus.[/SIZE][/FONT]
[FONT=Arial CE,sans-serif][SIZE=-1]The main tasks of the satellite are Earth remote sensing and vegetation detection with a medium resolution of about 300 m, store and forward communications for mobile localization and developing attitude control strategies for high resolution earth observation.[/SIZE][/FONT]
