Advanced EHF (AEHF) Architecture

AEHF and Milstar Will Operate as an Integrated Network for Users

5

• Provides secure, survivable anti-jam, anti-scintillation communications for strategic and tactical users• 24-hour low, medium, and high data

rate satellite connectivity from 65°N to 65°S latitude worldwide

• Assured mission-critical strategic networks

• Low Probability of Detection and Interception

• Successor to Milstar with greater capacity • Backward compatible with legacy

Milstar terminals• Cooperative agreements with

Canada, United Kingdom, and the Netherlands

AEHF New Capabilities

AEHF is More Flexible and Faster than Legacy EHF Systems

Increased Coverage, Capacity & Flexibility • 10x Improvement in System Capacity

• 5x Increase in Data Rate• 6x Number of Terminals • 3x Number of Networks

• Legacy Terminal Compatible• Satellite Command & Control

• 2x Capacity• Backward Compatible for TT&C of Milstar

• Responsive Mission Planning• Centralized Apportionment - Decentralized Control• 4x Increase in number of fences

• Milstar: 100 fences at single level• AEHF: 440 fences on three levels

• Resources assigned to a fence form a “virtual constellation” that cannot be co-opted

• UCCs have control over their assigned resourcesAEHF-1 in Acoustic Test

Protected Communications - EHF

•Milstar I/II • Survivable comm for strategic mission

• Up to 2.4 kbps (Anti-Scintillation)• Protected comm for tactical users

• Up to 1.544 Mbps (Anti-Jamming)• 40 Mbps capacity per satellite• 2 Milstar I & 3 Milstar II on orbit• Constellation has provided 50+ years of SATCOM to Warfighters

Advanced EHF(AEHF) Expanded survivable comm capabilities

Up to 19.2 kbps (Anti-Scintillation) Expanded protected comm capabilities

Up to 8 Mbps (Anti-Jamming) 430 Mbps capacity per satellite Four satellites International program: Canada, United

Kingdom, the Netherlands Backward compatible with Milstar I/II

AF Terminals support Protected satellites/services; developing expanded capability through FAB-T Inc 1, GEMS, MMP Upgrade and SMART-T

Future Technology: Advanced Concepts Group (ACG)

8

• Initiates space/ground Capability Insertion Programs (CIPs)• Terminals, networks, operations and user domains• Leads Pre-Contract activities for all MILSATCOM Products• Supports Industry Base

• Enterprise perspective across components• Standards, usage concepts, product alignments

• Harvests TSAT technology• Update/align residual artifacts supported by select supplier talent to new

Capability Improvements• Supports A5 requirements processes

• Projected FY10 AFSPC/A5-led Analysis of Alternatives (AoA) and MILSATCOM ICD

• CDD development - In FY11

More efficient enterprise alignment across MILSATCOMEnables Product Group focus on delivery
