Integrated Truss Structure

Struktur Truss Terpadu atau Integrated Truss Structure (ITS) membentuk tulang punggung dari Stasiun Luar Angkasa Internasional, dengan mounting untuk operator unpressurized logistik, radiator, array surya, dan peralatan lainnya.

Truss components

• Z1 truss
• S0 truss
• P1, S1 trusses
• P2, S2 trusses
• P3/P4, S3/S4 truss assemblies
• P5, S5 trusses
• P6, S6 trusses

Truss subsystems

• Solar arrays
• Solar alpha rotary joint
• Power conditioning and storage
