The OSD Unmanned Aircraft System (UAS) Control Segment (UCS) Architecture library was published in multiple releases from 2010 through 2015. The final release was R3.4(PR), where “PR” standards for public release. This library was handed off to the SAE AS-4UCS Committee at its inaugural meeting in April 2015. In December 2016, most of the R3.4(PR) library was republished by the SAE under AS6512™ while other documents were retired.
Here is the complete archive of R3.4(PR) configuration items, which can be viewed or downloaded. Note that each configuration item carries its own version number, which may or may not correspond with the release number of the library (depending on its update history). An overview of the library as a whole and of each configuration item is provided in the Architecture Description, UCS-INF-AD.
