BAUMANENTS spacecraft which is being developed by Bauman Moscow State Technical University in association with Federal Unitary Enterprise NPO Mashinostroenie is considered. Several options of satellite layout, considered at concept design stage are shown. Influencing factor is mutual influence of heat control system, structural elements and set of equipment on board of the satellite. Peculiarities of connection of the satellite with rocket launcher at launch facility are shown. Selection of major design decision is justified. Additional peculiarities of creation of the satellite is the fact that working drawings and documentation was developed immediately after concept design stage. Stages of experimental realization of the satellite are described. Detailed description of thermo-vacuum and electrical tests are shown: autonomous, connection, complex. Corrections implemented in documentation and construction at the stages of creation of systems and their implementation and tests are shown.
