Settle in, this is going to be a long one. Background. Oh so briefly. C-Band uses a 6 foot (2 meter) satellite tracking dish on ~3.5 GHz. It picks up the aircraft to ground crew communications. L-Band uses a 7 turn 3D printed helix (swapped out from a flaked out patch antenna only 3 days… Continue reading UA2781 lands at Midway Atoll on April 16th 2021

Tracking Inmarsat 4-F3 with Node-RED
This page is out of date.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
Data from plane tracking.
People are finding different uses for aircraft tracking data. https://www.bloomberg.com/news/articles/2019-07-02/hedge-funds-are-tracking-private-jets-to-find-the-next-megadeal Where there’s a jet, there’s a data trail, and several “alternative data” firms are keeping tabs on private aircraft for hedge funds and other investors. More power to them, and I am glad that my freely supplied data can make them money. (Wow, that sort… Continue reading Data from plane tracking.
Thermal drift issues
This page is out of date.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
C-Band ADSC aka Satellite ADSB
This page is out of date.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
