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.
Solar Panel Test
The test of our new solar panels was successful. The power output is 6 times the value given in the datasheet.

8-Channel Plasma Thruster Vacuum test
Succesful test of my 8-Channel pulsed plasma thruster. Let´s see how it performs in orbit.
