First four beacon packets from T-LogoQube (horizontal axis = frequency; vertical axis = time) Packets arrive every ~20 seconds. Each packet appears in the waterfall plot as a pair of points at two frequencies ~437.465 +- 0.012 MHz. The tilt of the pattern is caused by the doppler shift from higher to low frequencies as T-LogoQube passes over head. The tilted signals on the right side of the waterfall plot are from a different satellite. T-LogoQube Packets Every ~20 seconds
This waterwall plot shows a sequence of beacon packets saved in memory of T-LogoQube over a ~3 hour period that was commanded from the ground to dump in real time as T-LogoQube passed over head. The tilt of the packets is due to the doppler shift. The periodic dimming and of the signal is due to the spin of T-LogoQube. The vertical lines are terrestrial radio sources near the Little H-Bar Ranch in Petaluma (no doppler shift). Ground Command Stream of many T-LogoQube Packets Every ~4 seconds
