So IIRC for the last 50 years the DMSP satellites broadcast all their data in the clear. If the program is only shutting down the ground stations and data distribution, it seems like an opportunity for some researchers to buy some SDRs and start collecting their own data.
I'm actually surprised that the successors to DMSP don't meet the same needs. Or is the problem that they do and the government just doesn't share that data?
