Although entities like RS Access note that SpaceX has access to plenty of other spectrum to accomplish its broadband mission, SpaceX insists that the 12 GHz band has become one of the most important and intensely used spectrum bands for Americans who depend on satellite services. In fact, SpaceX said it depends on the 12 GHz band for the workhorse frequencies in critical downlink services to serve Americans “in every corner of the nation.” […] SpaceX would like the FCC to drop the 12 GHz proceeding, but Dish and RS Access have been urging the FCC for years to change the rules so that their MVDDS licenses can be used for two-way 5G services. In response to SpaceX’s submission, the 5G for 12 GHz Coalition, issued the following statement: “We understand that SpaceX has — after 18 months and both a robust comment and reply period — just filed its own in-house technical submission to the 12 GHz proceeding. Our engineers and technical experts are reviewing the filing in depth and remain committed to working in good faith with the FCC and stakeholders to ensure that the American public is able to reap the immense benefits of 5G services in this band.”

The app gathers information to track signal strength, the distance between the satellite and the phone being used, and the satellite’s carrier phase, according to Camaliot’s FAQs. With enough data collected from around the world, researchers can theoretically combine that with existing weather readings to measure long-term water vapor trends. They hope to use that data to inform weather forecasting models with machine learning. They can also track changes in Earth’s ionosphere — the part of the atmosphere near space. Creating better ionospheric forecasts could be relevant in tracking space weather and could eventually make Global Navigation Satellite Systems (GNSS) more accurate by accounting for events like geomagnetic storms. Camaliot could eventually expand to include more attempts at collecting data on a massive scale using sensors present in “Internet of Things” connected home devices. According to The Verge, these are the steps to take to begin using the Camaliot app on your Android phone:

1. Select “start logging” and place your phone in an area with a clear sky view to begin logging the data
2. Once you have measured to your liking, select “stop logging”
3. Then, upload your session to the server and repeat the process over time to collect more data. You can also delete your locally-stored log files at this step.

“In addition to being able to view your own measurements against others accumulated over time, you can also see a leaderboard showing logging sessions done by other participants,” adds The Verge. “Eventually, the information collected for the study will be available in a separate portal.”

Enercon has informed Germany’s cybersecurity watchdog BSI and is working with the relevant providers of the satellite communication networks to resolve the disruption, which it said affected around 30,000 satellite terminals used by companies and organisations from various sectors across Europe. “However, no effects on power grid stability are currently expected due to redundant communication capabilities of the responsible grid operators. Further investigations into the cause are being carried out by the company concerned in close exchange with the responsible authorities,” BSI said. There was no risk to the turbines as they continued to operate on “auto mode,” the company said. The report also notes that Viasat was “investigating a suspected cyberattack that caused a partial outage in its residential broadband services in Ukraine and other European countries”
