1 NAWCWD PR , May NAVAIR Ranges Encroachment Challenges Presented to: ITEA Blue Ribbon Panel 10 May 2017 Presented by: Mr. Tom Dowd Head, NAVAIR Ranges

2 NAVAIR Ranges NAWCWD Ranges R2508 Complex Airspace Approximately 20,000 square miles 20,000 feet (FL200) to unlimited altitude China Lake Land Ranges Approximately 1.1 Million Acres Surface to unlimited altitude IR-200 Low Level route connecting Sea and Land Ranges Point Mugu Sea Range Warning Areas 36,000 square miles; expandable to 220,000 square miles Surface to unlimited altitude Extensive area for supersonic testing Unique geography for Directed Energy Testing Atlantic Test Ranges Chesapeake Test Range Approximately 2,700 square miles controlled airspace Surface to 85,000 feet Offshore Ranges Access to 50,000 square miles in the mid-atlantic Warning Area Surface to unlimited altitude NAWCWD PR , May

3 Navy Encroachment Definition any non-navy action planned or executed which inhibits, curtails, or possesses the potential to impede the performance of Navy activities. Source: OPNAVINST , Encroachment Management Program NAWCWD PR , May

4 Encroachment Categories Frequency Spectrum Safety Arcs and Footprints Air Quality Water Quality Environmental Regulations Interagency Coordination Legislative Initiatives that Restrict Training or Testing Activities Urban Development Airborne Noise Competition for Air Space, Land, and Sea Space Competition for Scarce Resources Threatened and Endangered Species Maritime Issues Ordnance UXO and Munitions NAWCWD PR , May

5 Cumulative Effect of Spectrum Reallocation Relative spectrum available prior to 1992 WARC-92 reallocated 91.5 MHz OBRA-93 reallocated 235 MHz WRC-95 reallocated 66 MHz BBA-97 reallocates 20 MHz 2007 IMT-2000/3G reallocates 45 MHz for commercial use (45 MHz federal Spectrum ( MHz) 2010 National Broadband Plan (NBP) is looking at 500 MHz additional spectrum for Commercial Wireless Broadband (at least 250 MHz of Federal Spectrum, MHz to start) NAWCWD PR May2017 5

6 Latest Spectrum Reallocation Example MHz Military/Federal Systems MHz Broadcast Auxiliary Systems (BAS) JTRS ACTS PGM SUAS SATOPS TTNT AMT TRR ENG Ground SATOPS ENG Airborne Cable Relay MHz Some Military Systems/LTE ACTS JTRS MHz Military/Federal Systems SUAS MHz Military Systems & Broadcast Auxiliary Systems (BAS) ENG Airborne SUAS TTNT AMT TRR ENG Ground SATOPS TTNT TRR Cable Relay SATOPS Some DoD systems must be compressed in remaining MHz Enabling TTNT to tune in MHz replaces lost TTNT access NAWCWD PR May2017 6

7 How NAVAIR Ranges Are Spending SRF Actions needed to compress telemetry operations into MHz while simultaneously expanding telemetry operations to C-band Replace ALL airborne TM transmitters with at least Tier 1 (SOQPSK) spectrum efficient transmitters Protect all ground antennas against overload from LTE signals in MHz band Filters/high dynamic filters, if not already installed New antennas, if old ones not modifiable Add Tier 1 (SOQPSK) and Tier 2 (CPM) capability to all TM receivers not currently modified Purchase of new transportable TM trailers to augment fixed sites being modified (i.e. no impacts to RDT&E range missions and OPTEMPO) Purchase and deployment of new and/or improved spectrum monitoring and direction finding equipment Spectrum Management actions to improve frequency deconfliction tools and to protect all ground TM antennas regardless of registration status in government master file (GMF) or area master files (AMF) NAWCWD PR , May

8 AWS-3 Spectrum Monitoring Project Scope Upgrade NAVAIR Ranges Spectrum Monitoring and Geolocation capabilities Additional sites and Hybrid monitoring, direction finding and geolocation solutions include TDOA (Time Difference of Arrival), Angle of Arrival (AOA) and CI (Correlative Interferometry) Improve geographical diversity for spectrum monitoring and geolocation capabilities Upgrade DOD Middle Atlantic (MIDLANTAFC) and Western Area (WAFC) Frequency Coordinators frequency de-confliction and mitigation capabilities Fixed & Transportable Sites Mobiles Quick Reaction Capability NAWCWD PR May2017 8

9 NAWCWD PR , May 2017 Spectrum Access R&D (SARD) TM Projects C-Band/Multiband Telemetry Antenna Project consists of five subprojects identified as Technology Shortfalls in the CTEIP funded TSCRS (Tri-Service C-Band Roadmap Study) Report #1: Broadband Conformal C-Band Missile Wraparound Antennas (NAWCWD, follow on to S&T effort) #2: Beam Switching Array Antennas (Georgia Tech Research Institute; Atlanta, GA) #3: Multiband Conformal Antennas for Aircraft Applications (Toyon; Goleta, CA) #4: High Altitude Coronal Efforts on Antenna Performance (not awarded yet) #5: Small, Medium Gain Multiband Receive Antennas (Georgia Tech Research Institute; Atlanta, GA)

10 Where Do We Want to Go? Telemetry Network System (TmNS) Vehicle Data Acquisition Network Aircraft transitioning from one range to another Range 2 Mission Control Vehicle Data Acquisition Network Mission Control Range Operations Data Analyst Data Analyst ~52MHz Data Analyst ~45MHz Range Operations Data Analyst Range 1 52 MHz Supports multiple users on multiple ranges -60dBc -25dBm Bandwidth: -25dBm=~52MHz, -60dBc=~45MHz, 99%OBW=36.2MHz NAWCWD PR May

11 QUESTIONS? NAWCWD PR May

12 BACKUPS NAWCWD PR May

13 Rapidly Changing Operational Spectrum Environment Protective Legislation via NDAA-99/00 (PL & ) guarantee the Navy and DOD resources (i.e. money & time) to effect a peaceful transition (i.e. no impact to mission) from spectrum where we are primary into comparable spectrum NAWCWD PR , May

14 Efficiency Comparison of Telemetry Modulation Schemes Example 5 Mbps Signal MHz MHz MHz PCM/FM SOQPSK Multi-h CPM SOQPSK (Tier 1) Reduces Necessary Bandwidth by 50% Over PCM/FM Multi-h CPM (Tier 2) Reduces Necessary Bandwidth by 25% Over SOQPSK NAWCWD PR , May
