Determination of Mass Properties for the VX-SAT Communication Satellite
The determination of a spacecraft’s mass properties is critical during its conceptual design phase. Obtaining reliable mass property information, early in the design of a spacecraft, could prevent design mistakes that can be extremely costly in the development process. The process of the determination of the mass properties consist in a systematic work, that include the taking part of all the sub systems or design teams that conforms the preliminary tasks for the design of the communications satellite. The VX-SAT project is a system engineering exercise, realized in the China Academy of Space Technology (CAST) like training for the future designs in communication satellites for the Bolivarian Agency of Space Activities (ABAE) in Venezuela. This paper aim to show an analysis of the procedures in the calculation of the mass properties in communication satellite using suitable software’s and the importance of the process to collect the mass budget information to get the more reliable results. Also includes an overview of the VX-SAT system, the preliminary design of the structure requirements and finally the methods used to the analysis of the general determination of the mass properties with its results.
