Five SaudiSat fly in the space now. Three SaudiSat-1a, SaudiSat-1b, and SaudiSat-1c of those gets Oscar Number like SO-41,42,50. But SaudiSat-2 and SaudiSat-3 does not get Oscar number. As for the reason, the other satellites are not the amateur radios satellite, so the earth observing satellite and the commercial satellite. The purposes of the satellite are different. I JE9PEL wrote in the weight of the satellite at the yellow character of the chart below for the reference. You may judge the size of the satellites.
