Breizh Reconnaissance Orbiter

Breizh Reconnaissance Orbiter (BRO) is a low Earth orbit satellite constellation developed by the French company Unseenlabs,[1] headquartered in Rennes, Brittany,[2][3][4] with the support of the French Ministry of Research and Innovation.[5] BRO is focused on radio frequency spectrum monitoring and signal intelligence for maritime and aerial traffic surveillance.[5][6][7][8][9][10] The 6U and 8U CubeSat-type small satellites[11] are built by the Danish company GomSpace.[12][13] The first BRO satellite, BRO-1,[14] was launched in August 2019 on a Rocket Lab Electron rocket.[15][11][16][17][18]
