The USP, for Universal Space Platform (Russian: УКП, Универсальная Космическая Платформа), also known as Viktoria (Виктория), is a highly flexible satellite bus designed and manufactured by RSC Energia.[1][2][3][4][5][6] It is called universal because it has been designed to be operated from LEO to GEO.[1] It is a three axis stabilized platform with electric propulsion for station keeping, but chemical propellant is offered as an option.[1] The bus can offer up to 3000 W of power and a payload capacity up to 1,000 kg (2,200 lb) for Low Earth orbit or HEO an up to 300 kg (660 lb) for geostationary orbit.[1]

The platform is designed for direct orbital injection, and thus lacks orbit raising propulsion.[3] It does however, support dual launching on Proton-M, which can enable cheap launching, or the use of smaller vehicles like the Soyuz-2.1b/Fregat-M or even the Dnepr for low energy orbits.[1]

## List of USP bus satellites

While not the most successful satellite bus, the USP is characterized by its commercial beginnings and the huge orbital flexibility.
