This was the twenty-fourth flight of Invocon hardware on the Space Shuttle. During STS-117 mission, the Atlantis crew performed rewiring tasks to connect the new solar arrays to the power system. Two IVC systems were present on the orbiter and another was attached to the truss.

Below is a list of the IVC systems that were present on Atlantis during the mission. The EWB MicroTAU-WLE system is the IVC system used for detecting impacts on the leading edge of the Orbiter's wing.

Enhanced Wide-Band Micro-Miniature Tri-axial Accelerometer Unit

This is the fifth flight of the EWB MicroTAU system, a high-speed data acquisition network for dynamic acceleration sensing and recording. On STS-117, 44 units were used to detect, locate, and characterize impacts on the RCC panels on the wing leading edge.

Micro-Miniature Strain Gauge Unit

Twelve Invocon MicroSGU™ sensors were installed in the engine compartment to measure the stresses imparted to the trunnion arms on the Space Shuttle Main Engines (SSMEs).
