SpaceX Looking For Help With "Landing" Video 110

Maddog Batty (112434) writes "SpaceX recently made the news by managing to soft land at sea the first stage of rocket used to launch its third supply mission to the International Space Station. Telemetry reported that it was able to hover for eight seconds above the sea before running out of fuel and falling horizontal. Unfortunately, due to stormy weather at the time, their support ship wasn't able to get to the "landing" spot at the time and the first stage wasn't recovered and is likely now on the sea bed. Video of the landing was produced and transmitted to an aeroplane but unfortunately it is rather corrupted. SpaceX have attempted to improve it but it isn't much better. They are now looking for help to improve it further."

    ... until they post an analog recording of the telemetry. The bitstream *as decoded* is corrupted because of demodulation errors, and you can't reconstruct data that isn't there. If they have an analog recording, then analog filters can be applied to that in an attempt to create a cleaner input signal to the demodulator stage. An analogy: They have taken a picture of a page of text, rather out of focus and dark, and used OCR software on it. All they are giving us is the output of the OCR software. We need to see the original picture so we can apply better filtering/contrast adjustments to it before attempting pattern recognition.
