•
Broadband industry prefers pairing of spectral bands
•
Proposed paired band for 1695-1710 MHz not yet identified
– One band for phone-to-tower (Uplink)
– One band for tower-to-phone (Downlink)
– Band auctioned without paired band
– Less valuable  less revenue  110% minimum threshold lowers

Updates Since December MSR
•

•
•
Transition plan submitted Jan 22, 2014; approved Mar 4, 2014
– Relocation costs approved; OMB reduced ops reimbursement from five years
to three
– Documented GOES-R pre-auction costs previously submitted
– Radiosonde costs increased by $10M
Initial discussions with OSGS concerning monitoring system procurement
– Handover in work – drafting
– CONOPS and acquisition strategy in early stages – will engage OSPO
Departments of Interior and Defense enquired about about common
procurement of monitoring systems
Continuing to monitor FCC auction preparations

Key Transition Plan Caveats
• For NTIA
– Commitment of NTIA to develop coordination portal
– Engage FCC to ensure adequate enforcement mechanisms written into
rules
– Facilitate successful relocation of radiosondes to 401-406 MHz
• NOAA may come back to NTIA in future with additional critical
sites
• Identified high-risk and “showstopper” factors
– Adequate funding and proper phasing required
– Ability to validate commercial sharing methodologies
– Commercial broadband industry incentivized to make this work

Current Costs
• Radiosonde relocation: $80.139M (+10M)
• GOES-R pre-auction costs: $3.69 M (no change)
• NTIA-hosted design portal: $6.6M (no change)
– NOAA’s 1/3 cost-share only
– Covers ten years of operations (2015-2025)
• Monitoring system: $177M ($182M)
– Design, development, implementation
– OMB-directed reduction of 2 years’ operations costs ($2.5M per year)
• Total relocation costs include DOI and DoD costs

FCC Auction Status
• Draft Notice of Proposed Rulemaking circulated in April 2014
– Included industry comments to earlier draft and FCC adjudication
– 1695-1710 MHZ will be auctioned unpaired for uplink (phone to tower)
• Neither industry or the FCC have identified a paired band
• Greatly reduces auction value (Verizon called the unpaired band “useless”)
– Auction divided up into “Economic Areas” – more than one company
could win
– Auctioned in 5-10 MHz blocks – allows us to consolidate POES and
MetOp
• Auction still scheduled for September 2014 and public lawmandated licensing date of February 2015

Lightsquared - (1670-1680 MHz)
• Technical analysis completed and submitted to FCC
– Relocation of radiosondes to 401-406 MHz is feasible
– Sharing 1675-1680 MHz band with GOES is feasible with very large
exclusion zones
• Next actions
– Ball in FCC’s court – not obliged to do anything
– Lightsquared must coordinate with other federal users in 401-106
MHz before the FCC will consider any action
– Any proposed FCC actions will be sent to NTIA for USG comments &
clearance

Sentinel-1 C-Band Radar
• Operates in narrow part of C-Band surrounded by commercial
allocations for WiFi (think Starbucks)
• World Radio Conference 2015 (WRC-15) agenda item would
allocate remaining band to WiFi – shared with C-Band radars
• Potential interference to satellites could result in urban areas
• NOAA provided input to State Department position that testing
would be required to determine likelihood of interference
• EU linked agreements to share Sentinel-1 products to U.S. support

Personnel
• Transfer of NESDIS spectrum management responsibilities to
NESDIS CIO ASAP
–
–
–
–
All spectrum auction preparations
Routine filings and support to programs
Management of support contractors
Operational spectrum management (launch notifications, UAS flights,
interference
• CIO to recruit and hire spectrum manager to perform liaison
function with NESDIS spectrum users

NOAA S-Band (2200-2290 MHz)
•
Primary use
– DMSP commanding and mission data
– GOES-N & GOES-R commanding
•
New neighbors
–
–
–
–
•
Navy UAV and NASA aircraft test flights
DishNet deployment of 2180-2200 MHz nationwide broadband
Increased number of Wallops space launches
ISS COTS missions – orbital and reentry/recovery ops
Results
– Disruptions to Wallops ops during UAV missions
– Increased number of time-critical analysis tasks
– ISS COTS missions bring other NOAA sites into play

NOAA X-Band (7000–8000 MHz)
•
Primary NOAA use
– Downlink for SNPP and JPSS mission data
– GOES-N and GOES-R uplink and downlink
•
New neighbors – us!
– Different rules for polar downlinks
•
X-Band High-Rate Data (HRD)
–
–
•
Continuous direct broadcast not permitted
Requirement to shut off when not in field of view of ground station
L-Band POES/MetOp HRPT – continuous direct broadcast allowed
– Competition with numerous other X-band spacecraft
•
Results
– Resolved SNPP HRD downlink issue right before launch
– Analyzed and resolved potential interference issues at Fairbanks and Svalbard between
Landsat-8 and SNPP

NOAA C-Band (~5300 MHz)
• Jason 2 & 3 Poseiden-3 altimeter transmit band
• New neighbors
– Interference potential with FAA ground control radar
– In-band interference potential with Synthetic
Aperture Radar (SAR) spacecraft (RISAT and
RADARSAT)
• Results
– FAA issue resolved via live testing at NASA Glenn
– Analysis performed to resolve SAR issues – for now
