Universal stand for onboard information and navigation complex assembling and testing equipment of the spacecraft «GLONASS-K2»

The article is description of the developed universal assembly stand for fixing the technological plate and carrying out installation works and acceptance testing of the equipment on-board information and navigation complex of the «Glonass-K2» spacecraft developed by JSC ISS. The spacecraft is built on the basis of an unpressurized platform «Express-1000», operating on a medium-altitude circular orbit. The «Express-1000» platform is a constructively and functionally detached module that unites all onboard service subsystems that provide payload operation and provide all necessary resources and services for it. In the process of creating and assembling a spacecraft, the platform is combined with a payload, which is also a constructively and functionally detached module. On the basis of patent research and review of existing structures of the assembly stands, the most suitable working principle of the stand is selected. Theoretical calculations of the mechanism – strength, for a given resource are carried out. A constructive study of some of the most important units and equipment systems was carried out. A key feature of the stand is the introduction of an automated drive system with the possibility of remote control, which increases the safety of work with the stand. The stand is offered as a universal mechanism with the ability to assemble with different sizes of honeycomb panels.
