Disadvantaged Users
Across the internet, people enjoy a range of access performance, from low end analog modem
connections, to gigabit interfaces. Those with lower performance interfaces generally recognize the
limitations of their equipment and take advantage of services that are sized to fit their data handling
capacity. Content providers similarly recognize that many users will continue to access their services
through low performance connections and offer their services with options to tailor the content to meet
the user’s capability. Defense content providers have the same requirement, to make their products
accessible to the entire range of connection performance.
THE WAY AHEAD
Current UA communications capabilities must evolve into the future DoD net-centric vision. Current UA
support to the war fighter should be sustained while making the transition, but every effort must be made
to make the transition as soon as possible. This section outlines practical guidelines to enable the future
vision, including a summary of DoD written guidance, the DoD investments intended to produce common
hardware and software to facilitate communications mechanisms across UA weapon systems, and the key
leadership actions that can be taken right now to realize the net-centric vision soonest. The following
summary of direction to the Services and to industry is intended to be the roadmap to guide the UA
community’s transition to net-centricity.
DoD Guidance
There is already a body of written DoD direction that must be complied with while designing, building,
fielding and sustaining UA systems. OSD publishes policy guidance in the form of Memoranda,
Directives, and Instructions. This section provides the major policy statements that address UA
communications. It also provides sources for applicable standards. While policy establishes the “what”
of the guidance, standards establish the “how,” and support policy with implementation guidelines and
technical instructions.
Policy
Policy statements are organized into two groups. The first group directs transformation to a net-centric
force that universally operates on the GIG, providing direction for creating the GIG and the mechanisms
to enable information to flow freely across it. This includes implementation of interoperable transport

layers (IPv6), deployment of the TCA and transformation of circuit based DISN communications links to
IP based services.
Although smaller, the second group provides radio telecommunications guidance that enables wireless
connectivity to the GIG and is binding on all UA communications systems and waveforms. While current
UA systems support the warfighter through the common data link effort, implementation of common and
more flexible physical links with the JTRS program will be the next step. Guidance that implements the
GIG consist of:
􀂾 DoD Directive 8100.1, GIG Overarching Policy, dated September 19, 2002.
􀂾 DoD Chief Information Officer (CIO) Guidance and Policy Memorandum (G&PM) No. 11-8450,
DoD GIG Computing, dated April 6 2001.
􀂾 DoD CIO Memorandum, Subject: Net-Centric Data Strategy: Visibility-Tagging and Advertising
Data Assets with Discovery Metadata, dated October 24, 2003.
􀂾 DoD Memorandum, Subject: Internet Protocol Version 6 (IPv6), dated June 9, 2004.
􀂾 Chairman of the Joint Chiefs of Staff Instruction 6212.01C, Interoperability and Supportability of
Information Technology and National Security Systems, dated November 20, 2003.
Guidance that implements radio communications:
􀂾 OSD Memorandum, Subject: RF Equipment Acquisition Policy, dated June 17, 2003.
􀂾 OSD Memorandum for Secretaries of the Military Departments, Subject: JTRS, dated August 12,
2004.
􀂾 ASD Memorandum, Subject: CDL Policy, dated June 19, 2001.
􀂾 ASD Memorandum, Subject: C3I Tactical Data Link Policy, dated October 18, 1994.
Standards
Standards support policy by providing technical information in sufficient detail to guide system and
subsystem acquisition and development. These standards are mandatory for DoD weapon systems,
including UAS, and are only waived in exceptional circumstances. Table C-2 lists the key standards and
sources for standards.
The “source” column contains hyperlinks to the websites hosting the information. For detailed
information regarding a standard or source of standards, follow the respective link. Some websites will
require a user ID and password for access. Appendix E discusses standards that apply to various system
implementations.
