The Universal Space Platform was developed by S.P. Korolev
RSC Energia within the Yamal project. It has gone flight
qualification as a part of the Yamal-100 communication satellite
launched on September 6, 1999.
Using the Universal Space Platform as the basis, RSC Energia
provides activities in any scope:
- development and turn-key of communication systems and
Earth remote sensing (ERS) systems as a whole;
- development and launch of different-purpose satellites;
- platform adaptation as a part of specific space vehicle
of another developer.
Yamal-100 spacecraft unit
The Corporation manufacturing plant allows to build up to
6-8 spacecraft of this type per year. The production facilities
meet Russian and international requirements and standards.
For this purpose, a High-Cleanliness Industrial Room was
deployed in the Assembly-and-Test Center of the company,
which is unparalleled in the Russian rocket and space industry.
Key features of the Multi-purpose Satellite
- No pressurized compartments traditionally used in satellites.
- Compartments, solar array panels, on-board antennas
made of sandwiched honeycomb structures based on composite
- Power supply system based on solar arrays and Ni-H
- Passive thermal control system using heat pipes.
- Motion control system based on optical sensors, high-precision
angular rate meters and momentum wheels
- Electrical propulsion unit operating on xenon (liquid-
and gas-based are also possible)
- A single on-board control system based on an advanced
computer system which provides a functional unity for
all on-board systems is redundant, and is easily adapted
to the requirements of the specific payload installed
on the bus through the use of specialized software
The key feature of the design is a pronounced
modularity assuring high manufacturability and ease of the
integration and testing of the Multi-purpose Satellite Bus-based
