  • GNAO announcements:

  1. All documents provided on this webpage under the "Additional Reference Documentation" section are reference documents only. The information contained in these documents should not be taken as guidance by the AOB teams to design the AOB sub-system.
  2. The AOB teams are free to choose whichever optical design that will, as per their assessment, satisfy and optimize the AOB specifications, as specified in the document "2_GNAO-AOS-SPE-002-GNAO-AOB-Subsystem-Specification-Document-SSD-v2.0.pdf" (provided in the RfP package). Unlike the first RfP (released in 2020), this RfP does not request for the competing teams to assess and use one of the two design options that were originally proposed by the GNAO team at the Conceptual Design Review held in 2019.
  3. For the downselect to Phase B, the evaluation of everything related to the AOB to RTC interface implementation will be based solely on the information provided by the GNAO project to the AOB teams. This is also applicable for everything related to the AOB to GIRMOS interface implementation.
  4. During Phase A, direct or supervised interaction between the AOB teams and the other sub-system contractors cannot be allowed. However, during Phase B, the GNAO team, the AOB contractor and the other sub-system contractors will be able to collaborate more openly.

  • GNAO request:

The AOB teams are asked to create and update an "Action Item/Question Tracker" document. This document should reference all the requests for additional documentation and all the questions that the AOB team has asked to the GNAO project. The AOB teams are asked to provide an up-to-date version of this file before each monthly meeting.
