3382. ISS Mass Properties Analysis Process

Paper

Abstract

Providing mass properties analysis of the International Space Station is one of the primary responsibilities of the Vehicle Integration & Performance (VIPER) team of Boeing IDS, Space Exploration, Program Integration. This task has evolved over the life of the ISS program to be a cooperative exchange of data between Boeing, NASA?s prime contractor for the United States On-Orbit Segment (USOS) and Energia, the Russian Federal Space Agency?s primary contractor for the Russian Segment (RS). The primary use of ISS mass properties data is for input to the Guidance, Navigation and Control (GN&C) System for both the US and Russian systems. The existence of dual GN&C systems demands that both systems are using the same set of mass properties data at all times. This duality of systems has led to the creation of Mass Properties Data Exchange Protocols between NASA and RSC-Energia. Other primary users of ISS mass properties data and analysis include Loads & Dynamics, Stowage Integration, and Logistics & Maintenance. This paper will present the process by which ISS mass properties analysis is generated and reported to the multiple users in the ISS Program.
