Space Shuttle Atlantis
This was the twenty-second flight of Invocon hardware on the Space Shuttle. The STS-115 mission marked the return to ISS construction after the loss of Columbia during STS-107. During this mission, the Atlantis crew attached the P3 & P4 Truss segments to the ISS. 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.
| 44 | EWB MicroTAU™ | Wing Leading Edge |
| 12 | MicroSGU™ | Aft Section |
| 1 | EWIS | Network Control Unit |
Enhanced Wide-Band Micro-Miniature Tri-axial Accelerometer Unit
This is the third flight of the EWB MicroTAU system, a high-speed, synchronized data acquisition network for dynamic acceleration sensing and recording. On STS-115, 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).
This makes the ninth consecutive flight of the MicroSGU system starting with STS-109.
