Azur (also called GRS-A) was West Germany's first scientific satellite. Launched on 8 November 1969 it studied the Van Allen belts, solar particles, and aurorae.[2] [3]
The construction of the satellite was carried out by Ludwig Bölkow, one of the aeronautical pioneers of Germany, and with the participation of other German companies.[4]
