[amsat-bb] Doppler Tracking Discontinuity at TCA - Problem Solved

[Phil Karn]

I know about the Itar limits, but the fact that some manufacturers implemented the limits as altitude AND velocity while others did it as altitude OR velocity was certainly arbitrary.

I didn’t know that these limits had been removed entirely, that’s good news. I’d noticed that the kiwi sdr has an open GPS receiver in it, which got me thinking about extracting and using it independently.
