Hardware Command Panel (HCP)
The ISS crew can control the HTV during its final approach to the ISS
using the Hardware Command Panel (HCP) for immediate critical
operations, in addition to using their command/monitor laptops (PCSs).
The key functions of the HCP are “ABORT”, “RETREAT”, “HOLD”, and
“FREE DRIFT”.
The HCP will be deployed temporarily on the robotics workstation in the
Destiny laboratory module during HTV’s Proximity Operations. After
Tranquility (Node 3) arrives at the ISS, the HCP will be deployed in the
“Cupola” of Tranquility.
