Since Artemis I, I began research into a method of Doppler extraction that doesn't rely on a carrier, demodulation or FFT. I can report success! Nearly complete pass with heavy tree attenuation.🧵⬇️04 Apr 2026 03:33 +0000at://did:plc:ryvs4qghgdxcehszmairzilj/app.bsky.feed.post/3mincfvbgys2dhttps://bsky.app/profile/coastal8049.bsky.social/post/3min4rdbvrk2hThis screenshot appears to reveal success in my new way of reducing Doppler without using a FFT from signals like Artemis II is using. My software is firmly locked on Artemis II and reducing Doppler all without demodulation or FFTs...
