The JTRS program will oversee development of a family of software-defined radios, based on a set of common hardware components and software applications.  All UA programs that require radios must synchronize purchases with the JTRS schedule.  In cases where JTRS radios are not yet available, these programs must obtain a waiver, procure the minimum required number of legacy radios, and have a migration plan to procure and install JTRS counterparts as they become available.
Figure C-11 shows IOC dates for key UA related JTRS programs.  Cluster 1 and the MIDS JTRS should reach IOC in 2007.  USN/USA will demonstrate and begin fielding Fire Scout with an integrated SCA compliant CDL (TCDL), using a JTRS Cluster I terminal equipped with a high-band modem module.  AMF JTRS is expected to reach IOC in 2009.  This schedule may change, but it remains a requirement for UA programs to coordinate all future radio purchases with the JTRS program office.  For more detailed information about JTRS Clusters refer to the section entitled “Joint Tactical Radio System.”  Additional information about the JTRS program and means of contact can be found at http://jtrs.army.mil/index.htm.

FIGURE C-11. CONSOLIDATED HIGH LEVEL PROGRAM SCHEDULE.
TSAT
DoD relies extensively on SATCOM for UA command and control as well as product dissemination. Reliance on foreign commercial vendors, however, entails some risk. A government owned, broadband, SATCOM constellation will reduce reliance on commercial SATCOM and provide more available and cost effective BLOS communications support to UA operations. For a more complete description of current UA communications, refer to the section entitled “Historical Perspective,” and its discussions of Global Hawk and Predator operations.
The TSAT constellation implements the space borne component of the GIG, moving data globally through an orbiting optical and RF based network. The first TSAT is scheduled for launch in FY13 (CY12). An additional TSAT will be launched each year until all 5 TSAT systems are established in their geosynchronous orbits (Figure C-11). TSAT will connect to the terrestrial backbone via teleports located at strategic points throughout the globe. TSAT will be transparent to most GIG users, and be experienced simply as a high data rate transfer capability.
UAS, such as Global Hawk and Predator, will connect to TSAT directly through the FAB-T, which include both RF and Optical data links.
High Assurance Internet Protocol Encryption Devices
The principal objective of Information Assurance is to assure access to authorized users while denying access to unauthorized users. For example, imagery exploiters and operations center personnel may need UA data, but a medical technician does not. Historically the separation has been accomplished through physically securing the classified networks, and encrypting the information as it leaves the protected facility. Circuits that transfer unencrypted classified information are designated red in security accreditation plans. Circuits carrying unclassified information or encrypted classified information are designated black. Open connections between red circuits and black circuits are prohibited. This principle of red/black separation guides the design and implementation of classified information processing facilities.
