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
This page is out of date. Please go to my GitHub site: https://thebaldgeek.github.io/ Getting back to looking at HF ACARS messages again and so with that comes the need to tune to the best HF frequency. (Best is still based on propagation and is a topic for another blog). My HF station is in Arizona,… Continue reading Remote control of SDRuno with MQTT and Node-RED
Sorry guys, did not realize that I had not blogged about my Inmarsat fun and games….. There are a few different ways that aircraft communicate back and forth with the airline. This blog is about satellite. There is a geostationary (not moving, very handy, no tracking needed) satellite named Inmarsat (sorry, forget the exact number,… Continue reading Inmarsat ACARS
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?
UPDATE! I am writing up instructions and Node-RED flow code on my GitHub page: https://thebaldgeek.github.io/ Turns out that aircraft blat out more than just their positions. They also send a lot of short messages that anyone can receive and to some extent decode and make some sense of. This has been keeping me busy for… Continue reading ACARS
