Please go to my GitHub site: https://thebaldgeek.github.io/ You may recall from the very end conclusion of the blog entry on my ADSC C-Band ground station that I had two outstanding issues. Tracking the sat. Thermal drift on the output. The sat issue is the nature of physics. The thermal… Continue reading Titanium C1-PLL LNB GPSDO Modification for C-Band ADSC
This page is out of date. Please go to my GitHub site: https://thebaldgeek.github.io/ For a year now I have been ‘tracking’ Inmarsat 4-F3 for my C-Band ADSC aircraft receiving ground station. It has been very crude tracking, but tracking none the less. I used a linear actuator with a position feedback resistor. Its worth noting… Continue reading Tracking Inmarsat 4-F3 with Node-RED
This page is out of date. Please go to my GitHub site: https://thebaldgeek.github.io/ The feedhorn / down converter on the dish has a pretty bad thermal drift issue. The output frequency is just not stable. It wanders around all over the place. We have tried to settle it down by insulating it like thus; It… Continue reading Thermal drift issues
This page is out of date. Please go to my GitHub site: https://thebaldgeek.github.io/ When you write it down, in one sentence, its really very simple; 6′ dish -> PLL LNA -> 18v DC pass-through PSU -> RTL-SDR -> SDR# -> Jaero -> VRS. And with that signal path, you will have planes on a map.… Continue reading C-Band ADSC aka Satellite ADSB
We have been interested in building a one stop shop website for all things aircraft tracking and decoding for some time. To this end we have put up a satellite dish to get Inmarsat messages, 136mHz antennas for ACARS and VDL data and for HF we have been running an Alinco receiver. Everything has been… Continue reading Noisy computers?
