The YES2 Integration Manager performs more visual inspections on YES2, while connecting an Electronic Ground Support Equipment (ECSE) cable to the YES2 payload after mounting in the MIK12 Integration Hall. The EGSE is used for functional and interface testing on the final launch configuration between YES2 and Foton. This testing will test that signals can be sent and received between YES2 and Foton and between Foton and Mission Control. Power transfer systems are also tested during this phase.
