The challenge remains to link disparate systems, effective in their own right, but evolving separately over time, to form a cohesive collaborative information environment. To this end, DoD has invested in its own version of the internet, the GIG. The GIG, defined as virtually all DoD information technology infrastructure, exists to provide the timely and accurate information that war fighters need to assure victory. All DoD Systems shall be able to interact with the GIG. New UA systems shall be developed to comply with the GIG architecture from the outset. At a minimum, web enabled interfaces for legacy UAV systems would need to be created for the system to be recognized as an entity on the GIG. By connecting to the network, UAS become part of that network.
Everyone on the GIG will become both a producer and a consumer of information. The concept of sensor will extend to virtually every piece of equipment capable of sensing and passing data, from orbiting satellites to an individual soldier’s gun sights. This information must flow seamlessly, with minimal human intervention, to unanticipated users as well as well defined, known users, to support both foreseen and unforeseen information requirements.
The two overarching requirements for next generation UA communications are 1) connect to the GIG, and 2) comply with spectrum utilization policy. To connect to the GIG, UA programs must take full advantage of DoD programs and initiatives to achieve net-centricity: net enabled CDL, JTRS, Transformational Satellites (TSAT), High Assurance Internet Protocol Encryption (HAIPE), and the Defense Information Systems Agency (DISA) metadata registry. UA communications must provide secure, reliable access to all UA capabilities across the entire DoD enterprise. Initially, efforts must focus on common interfaces for sensor control and dissemination via the GIG. As new payloads and weapons are introduced, such as communications relay packages, electronic warfare suites, and guided weapons, web enabled interfaces must be developed to allow control and employment from any authorized node. The vision is a ubiquitous network where every entity exists as a node and can share and use any data produced by any other node, anytime.

EXPERIENCE
A review of operations in support of recent conflicts serves to illustrate current communications capabilities for two UAS, Global Hawk and Predator. They employed a mix of dedicated point-to-point communications and networked communications. Many of the networked communications were IP based, approaching net-centric capabilities. Examples of network capabilities include posting images to an Image Product Library (IPL), which implements the Task, Post, Process, Use (TPPU) model, and the widespread use of secure internet chat.
