HRC Command Sequences

This page contains a list of the identified command sequences for HRC operations. These can be pieced together to perform higher-level sequences of HRC activities or to handle contingency operations. The HRC team reserves the right to add to, delete from, and change this list as operational needs are identified.

Note: Multiple implementations (stored command sequences and scripts of ground commands) of some of these sequences may be required to accomplish the activities during different mission phases.

Power and Configuration

• Power Configure HRC to use CEA A
• Disable HRC Mechanism Failsafes
