Folks, We tried to warn you about #5G... Slide from April 2021: Sai Kalyanareraman of Collins Aerospace said to Friends and Partners in Aviation Weather that "Interference to radar altimeters could endanger safety of life airborne operations" All slides: fpaw.aero/sites/default/…

News: 5G network deployment in the U.S. spawns a cluster of disruption (via The Air Current) "The aircraft’s radar altitude abruptly ran down to zero, causing repeated loud aural warnings: PULL UP WHOOP WHOOP DON’T SINK TOO LOW GEAR." Read more: theaircurrent.com/aviation-safet…

Upcoming radio spectrum panel discussion at the American Meteorological Society annual meeting: "How Secure are our Models and Satellite Observations? Realities of Spectrum Interference" Join us virtually Wednesday, 26 January 2022, at 2:30 PM ET. Attendees must be registered for the annual meeting.

We applaud the bipartisan Senate letter urging FCC to stay & reconsider the Ligado Order. Their grave concerns reflect the overwhelming concern of 14 federal agencies & vast federal /commercial user base of #GPS, #satcom & weather forecasting services. safesatellite.org

#RethinkLigado Reliable access to GOES Data Collection Platform Relay (DCPR) and GOES Rebroadcast (GRB) is at stake. Without FCC action soon, Ligado will operate noisy telecommunications systems near quieter space-to-earth relays for GPS, satellite comms, and weather services.

What we have been saying 👇

The American Meteorological Society and AGU (American Geophysical Union) joined others in the weather enterprise to highlight the Spectrum Pipeline Reallocation 1675–1680 MHz Engineering Study (SPRES) report finding that users of NOAA Satellites are likely to encounter interference if bands are shared: files.fcc.gov/ecfs/download/…

Chairwoman Johnson and Ranking Member Lucas urge FCC to limit spectrum sharing to avoid harmful interference in the 1675-1680 MHz band science.house.gov/news/press-rel…

🔊 JOIN US THURSDAY, JANUARY 12TH, at 1:30 PM MST #AMS2023 Presidential Session: "Spectrum's Critical Role in Weather and Climate Data: How Do We Move Beyond Regulatory Conflicts to Science-Informed Innovation?"

⚡️New post⚡️: This crazy, beautiful chart from the NTIA illustrates the incredible complexity of managing one of our nation’s most crucial – and invisible – national assets: the radio spectrum. 📻 beautifulpublicdata.com/the-united-sta…

Three years from the Ligado order, we are joining 91 groups to urge President Donald J. Trump and Congress to work with the FCC to stay the order. An independent study from National Academies conclusively showed Ligado threatens vital GPS, SATCOM, and GOES services. #RethinkLigado safesatellite.org/filings/satcom…

But weather satellites will be key to creating his routes and last minute weather info also. NOAA Satellites Like its Joint Polar Satellite System (JPSS) satellites with passive sensors near 24 GHz and 50-58 GHz to inform weather models for Santa's advance forecasts.

🔊 JOIN US MONDAY, JANUARY 29, at 4:30 PM EST, in the Baltimore Convention Center Room 307 and online #AMS2024 Joint Session on Radio Frequency Spectrum: "What's the Forecast for RF Spectrum? Exploring the Way Forward on Spectrum for the Weather-Water-Climate Enterprise in 2024"

Join us TODAY! #AMS2024

4 years later, several scientific studies confirming harmful interference to GPS and satcom, and continued widespread opposition by stakeholders, the FCC has taken ZERO action to address the flawed #Ligado order. Learn more about this massive mistake: safesatellite.org

Despite current Int’l Telecommunication Union rules on use of the electromagnetic spectrum, satellites sometimes suffer from interference – radio frequency interference, or RFI. This can mean loss of data, risk of damage to the satellite receiver and biased or uncertain measurements. The animation
