Mass of cables implemented on-board a spacecraft is one of the drivers taken into account during spacecraft design phase. One of the requirements is to provide a high ratio between Payload and Spacecraft mass because the contribu-tion of cable lines to spacecraft mass budget is significant, and cable lines have significant lengths, so mass of cable lines becomes a challenging issue. The article identifies and assesses major criteria considered during design of power lines belonging to telecommunication satellites harness. Major contributors to satellite mass budget has been identified, a description of major competitors among world level satellite platform manufactures is given, a comparison of masses of satellites manufactured on the basis of powerful Platforms, i. e. E3000 and Express-2000 is provided. The need to consider such generic criteria as mass and cost during selection of harness manufactures is described. Reduction of on-board harness mass is possible when new, state-of-the-art technology is used. The technology should have a flight proven heritage and shall be widely used by satellite manufacturers in Russia and worldwide. The advantage of imple-mentation of power lines ensuring reliable power distribution which are vital elements of telecommunication satellite electric power subsystem has been reviewed. Implementation of state-of-the-art Axon’ Bus Bar technology, allowing to reduce satellite harness mass and to achieve reduction of satellite mass resulting in decrease of launch cost is being justified.
Keywords: Bus Bars, on-board harness, reduction of spacecraft harness mass.
