USP (satellite bus)

The USP, for Universal Space Platform (Russian: Универсальная Космическая Платформа, romanized: Universal'naya Kosmicheskaya Platforma; Russian: УКП, romanized: UKP), 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] While not the most successful satellite bus, the USP is characterized by its commercial beginnings and the huge orbital flexibility.
