STANAG 4586–Standard Interfaces of UCS for NATO UAV Interoperability 
 
 
 The NSIF standard alone does not guarantee interoperability. Other aspects of the interface between systems 
(e.g. recording media, transmission protocols, etc.) must be considered based on other standards [2]. 
3.2 
STANAG 4575: NATO Advanced Data Storage Interface (NADSI) 
NATO Advanced data storage interface defines the standard for an interface to allow cross-servicing of ISR 
platforms by NATO nations´ground stations. The NADSI defines a multiple layer protocol for the lower 
levels of  the interface channel as defined in the International Standards Organizations – Open Systems 
Interconnection model (ISO/IEC 7498-1) [10].  
The interface is a high data rate port to allow direct download of the imagery and auxiliary data, either at the 
air platform or at the ground station. Once the memory has been transferred to a reconnaissance exploitation 
ground station, it can be exploited using normal tools [2]. 
This STANAG also defines the physical, electrical data/control, and power interface as well as the connector 
specifications [10]. 
The NADSI standard alone does not guarantee interoperability. Compatibility must also be assured at other 
protocol layers. Certifiable implementation of the NADSI for support of interoperability is subject to 
constraints not specified in this STANAG [10]. 
3.3 
STANAG 4607: NATO Ground Moving Target Indicator (GMTI) format 
The NATO Ground Moving Target Indicator Format (GMTIF) defines a standard for the data content and 
format for the products of ground moving target indicator radar systems and a recommended mechanism for 
relaying tasking requests to the radar sensor system [11]. 
The GMTIF is a binary, message-oriented format for the prompt dissemination of Moving Target Indicator 
(MTI) data. It may be sent as a stand-alone format or it may be embedded in a frame-oriented format, such as 
the NATO Secondary Imagery Format (NSIF, STANAG 4545) or the National Imagery Transmission 
Format (NITF, Military Standard-2500) for the dissemination of secondary imagery, or in a message 
oriented format such as the NATO Primary Imagery Format (STANAG 7023) for the dissemination of 
primary imagery [11].  
This STANAG includes a notional employment concept for using the GMTIF, a suggested technique for 
embedding GMTIF data into NATO imagery formats, suggested groupings of GMTIF data fields to support 
three data exploitation classes, and tutorial information pertaining to the GMTIF [11]. 
The format provides a flexible format for target information, such that simple GMTI systems can use a small 
subset of the format with limited bandwidth channels, while robust systems can encode all aspects of the 
output data for use with wideband channels, including high range resolution (HRR) and pulse Doppler 
modes. It is also configured to be used as a stand-alone format, or can be encapsulated in either STANAG 
4545 or 7023 data streams. Target reports include such information as target location and radial velocity. 
Further value-added processing of the target movement can produce track histories of the individual targets 
[2].  
3.4 
STANAG 4609: NATO Digital Motion Imagery Standard 
Motion Imagery (MI) is a valuable asset for commanders that enable them to meet a variety of theatre, 
operational and tactical objectives for intelligence, reconnaissance and surveillance. STANAG 4609 is 
intended to provide common methods for exchange of MI across systems within and among NATO nations 
[12].
