Russia fired six foreign satellites into orbit, from the Baikonur space centre in Kazakhstan, Russian military spokesman Alexander Vovk said.
"Six satellites, namely the DubaiSat-1, Deimos 1, UK-DMC 2, Nanosat 1B, AprizeSat 3, AprizeSat 4 were put in orbit yesterday by the Russian launcher Dnepr," Vovk said, according to the Interfax news agency.
The rocket was launched at 10:46 pm Moscow time (0016 IST Thursday), he added.
The emirates' satellite DubaiSat-1 has been designed for soil surveys, said Interfax. Spain's Nanosta 1B will be used for experiments in nanotechnology.
Britain's Deimos-1 and UK-DMC 2 are part of a constellation of satellites to be used for disaster monitoring, built by the British company SSTL.
Spain's Deimos will be used for agricultural and environmental research.
Argentina's satellites, AprizeSat 3 and Aprizesat 4, were both for telecommunications, said the agency.
