PostHeaderIcon ADS-B PocketQube is taking shape


Here is a running ADS-B test on the engineering model inner structure of the satellite.
The signal reception is great, getting more than 44dB above the noisefloor (upper graph, 19.9mV/dB), a rare situation though, because it´s not much nearby traffic here.
Lower graph shows a weak signal, barely above noise at -92dBm. The bits still look decodable – I´ll continue optimizing. It´s a bit of a challenge.
In average, there are many many signals per second with 10-20dB over noisefloor with no visible planes.
