OPSCOM-1 Notes
• Experiment was performed using CGBA as a proxy onboard to route traffic to the METERON laptop
• Cu-Boulder’s ground site was also used to proxy DTN traffic to ESA– No ACS was used for this experiment– Custody Transfer was not used for this experiment

METERON Laptop Configuration• OPSCOM-2 will be executed in 3rd annual quarter 2014
– Custody Transfer will be enabled– ACS will also be used for this experiment
• The METERON ISS Laptop will need to be reconfigured to route directly to HOSC DTN Node– ESA has access to this load and will make the configation changes for
the onboard laptop– ESA will also need to make similar configuration changes to the DTN
node located at B.USOC – MSFC will make the necessary database modification to route the
redefined ESA bundles and data appropriately– MSFC will provide ESA with a Payload Rack Checkout Unit (PRCU) to
verify the changes in a high fidelity test environment
