Frequency Issues Breakout Session• Is there anything about the Broadband initiative and its impacts that you
would like me to explain in more detail?• Summary of changes resulting from broadband initiative
• Current GOES products & services: No change• Current polar products: No change until/if sharing initiated• GOES-R: GRB, EMWIN/HRPT not affected – frequency may change• JPSS: HRD not affected; LRD may be affected
• HRPT-like broadcasts likely to continue well into 2020s (MetOp-C)• Timing of auction unknown• Purchase of spectrum by broadband industry and ultimate use uncertain• We must proceed as if sharing will happen within 5 years in the U.S.
Frequency Issues Breakout Session• Is there anything about the Broadband initiative and its impacts that you
would like me to explain in more detail?• Short overview of NOAA radiosonde operations & effects upon
interference in L-Band• Questions & discussion topics for polar HRPT users
• Do you experience interference today? If so, how bad is it? Is it predictable? Do you know what causes it? Have you reported your interference to NOAA?• If you are located outside a future exclusion zone, what impacts to
your operations do you predict?• What aspects of your operation will be affected? How? Impacts?• Is there anything we can do to minimize the probability of
interference? Shielding? Location of antennas? Beam characteristics?
Present-Day
Fast-track Shared Spectrum
GOES-R & JPSS Era: 2016+
Current GOES & PolarCurrent end of lifeGOES-15: mid-2020Polar: 2022 (MetOp-C)
6-10 year overlap period when legacy & new are operating
15 MHz Shared
Band Recommended For Fast-Track Sharing
3
Future
“Sharing” will be implemented with goal of preventing harmful interference between government & commercial sectors
