There are already a number of existing or emerging STANAGs that are applicable to UA systems. They provide standards for interoperable data link (STANAG 7085), digital sensor data between the payload and the AV element of the data link (STANAG 7023, 4545), and for on board recording device(s) (STANAG 7024, 4575). Additionally, the STANAG 4586, unmanned control system (UCS), describes interfaces applicable to ground control stations and air vehicles, to include air vehicle control. Although somewhat limited as to broad mission area application, this STANAG contains an interface description, the DLI, which provides an excellent starting point for the development of a robust air vehicle interface, to include vehicle control functions. Thus, the approach to achieving the desired level of UA interoperability is based on compliance with existing standards or establishing new standards for a number of UA functions.
.  
An open network architecture using industry standards including internet protocol, Ethernet and generic framing procedure.

.  
A data link system(s) that provides connectivity and interoperability between the UCS and the AV(s).  The data link system(s) must accommodate legacy as well as future systems. STANAG 7085, Interoperable Data Links for Imaging Systems, specifies a data link system that would provide the required connectivity and interoperability. The data link must just provide for transmission of data over the RF link, not be the interface for the sensor and flight management functions or do routing functions.

.  
Format for payload/sensor data for transmission to the UCS via the data link and/or for recording on the on-board recording device. STANAG 7023, NATO Primary Image Format Standard, with addition for non-imagery sensors, (e.g., electronic support measures (ESM)), and STANAG 4545, NATO Secondary Imagery Format, are the required data formats for imagery. If GMTI data is to be used, STANAG 4607 defines the required format, and STANAG 4609 defines the format for digital motion imagery.

.  
Recording device for on board recording of sensor data, if required, STANAG 7024, Imagery Air Reconnaissance Tape Recorder Standard, and STANAG 4575, NATO Advanced Data Storage Interface, specify standard recording devices and interface respectively.

APPENDIX E – INTEROPERABILITY STANDARDS

.  A standard describing the interfaces and messages necessary to control an air vehicle. A starting point for this activity is the DLI segment of STANAG 4586.
PROCESS FOR SELECTING STANDARDS
UA standards are usually selected for implementation by a development program from those in the DISR.  New standards are added to the DISR periodically and existing ones updated based on technological advancement. However, the DISR is very broadly written to encompass the full range of interoperability needs. Therefore, subsets must be chosen for specific mission areas, such as UA. Additionally, some needed standards are not specifically included in the DISR, due to time lag as new technologies emerge or due to lack of specificity for lower level protocols. Currently, there is not a formal process in-place for choosing subsets of the DISR standards for UA application except during development of the UA Roadmap. The fundamental criterion for standards selection should be whether or not the proposed standard will improve UA systems interoperability.
