EGS On-Boarding


$60 USD each


Thursday – February 23, 2023


8:00 AM – 10:30 AM PT


EGS has developed an onboarding package that has been through multiple rounds of review culminating in a collection of documents, templates, and criteria to further mission partner knowledge of transitioning to EGS. These artifacts provide guidance and instruction on accessing EGS repositories, high-level outlook of the program, and outlines for tailoring memorandums and service level agreements with external partners. EGS has also defined levels of compliance for the physical layer, space-to-ground communications layer, platform/host layer, application layer, and enterprise support layer to include threshold and objective requirements to achieve a minimum level of EGS-compliance. In support of these compliance criteria, established messaging standards in the form of Interface Specification Documents (ISDs) are also available that identify the messages available for use to communicate between services via the Enterprise Message Bus.
