Mass data storage. Onboard storage of sensor data in the terabyte class should be a goal to exploit manned and unmanned sensor data. Storage of complex imagery or phase history of radar data onboard can substitute for the extremely wideband data links required for near-real-time relay. Similarly, storage of the full output of a hyperspectral sensor will allow transmission of selected bands during a mission and full exploitation of data post-mission. The stored data is crucial in building an HSI phenomenology database to select the right diagnostic bands in the first place.

The goal for onboard mass data storage should be to replicate the capability of wet film for broad area synoptic coverage. Current medium resolution film cameras operating at high altitude can image over 17,500 square nautical miles in stereo on a single mission of a few hours, a capability unequalled by airborne digital sensors at this time. A 1.4 Terabyte storage capability coupled with an imagery index system and IP-enabled interface has been demonstrated on Global Hawk. Known as the Advanced Information Architecture (AIA), this system permitted the capture of over 3 days of full resolution Global Hawk imagery and enabled users to access the imagery using internet search tools. The storage system and IP server were constructed using COTS components and integrated into the existing space allocated to the DCRSi recorder suite, using a DCRSi system interface so that no change to the Global Hawk operational software was required, with space remaining to also integrate a line-of-sight UHF access system to permit operators to receive imagery without the need to go through a dedicated ground station. AIA’s design around COTS components and IP-enabled interfaces will make the transition to solid-state memory arrays, when they become cost effective, a relatively easy upgrade. The Department highly encourages demonstrations such as AIA, on-board mass storage systems based on STANAG 4575 (NATO Advanced Data Storage Interface), supporting both sensor data archiving and the dissemination of data to users upon demand, in accordance with DoD’s TPPU concept.

APPENDIX C: COMMUNICATIONS
INTRODUCTION
This appendix guides industry and the Services on an UA communications migration path toward improved interoperability. Service acquisition functions include requirements offices, program offices, acquisition managers, program managers, and research and development programs. Service operators include operational units, and demonstration activities. Industry includes developers, manufacturers, and professional standards groups. This appendix provides a reference to existing and binding policy and standards. It also provides time frames for implementation of various capabilities.
Overview
The information environment has changed fundamentally over the last 10 years. More importantly it will continue to change. The Services, in partnership with industry, must develop and field interoperable UA systems that can adapt to the evolving information environment.
