As an aside, about a year ago there was an kind-of interesting deep dive about Francis Malofiy, the lawyer for the Spirit estate, in Philadelphia magazine.
GPS signals use several blocks of the L band, including a primary channel centered on 1575.42MHz. GPS uses L band signals because of their ability to penetrate cloud cover, rain, and vegetation. The L band is also used by the DOD for a number of other purposes, including tactical air navigation, landing assistance telemetry, Identify Friend or Foe (IFF) signals, and missile range and aircraft telemetry—though the DOD has already had to move some of these applications further up the spectrum range to make room for previous "commercial reallocation."
Have all the voices expressing concern that the current (and future) 5G signals and noise levels will interfere with various frequencies used in weather forecasting and GPS been completely drowned out?
In the report from the last World Radiocommunications Conference ( link) it seems like they are just calling for several studies to be done "...in time for WRC-23..." which will apparently be scheduled for some time in 2013 (link).
While I am sure it will take some time to accurately determine exactly which frequencies, signal levels, and noise levels will acceptable or unacceptable, this seems like it could be a bad case of kicking the can down the road. After 2023, when the studies are done, I wonder how much longer it will take the ITU to come up with concrete recommendations or limits for permissible frequencies, signal levels, and noise levels. And when they finally do make these determinations, will it be too late? Will the telecom companies already have made huge investments in 5G infrastructure? Will weather forecasting and GPS capabilities already have been sacrificed on the altar of telco profits?

According to this [article] (https://arstechnica.com/tech-policy/2019/11/dod-joins-fight-against-5g-spectrum-proposal-citing-ris ks-to-gps/) the DOD has already had to move some things to make room for commercial interests:
