What
A VM running on Coherence (sdr.dhcp.nurd.space / 10.208.42.113) tracking airplanes, in total there are 3 RTL-SDR dongles connected while only one is being used for ADS-B. The other two remain available for any other SDR purposes. The ADSB decoder used is ReadSB some of the services are running under Docker. The setup is heavily based upon this [1].
For the time being, until we restart Coherence (to enable nesting) the following services are still not running:
The following services still need to be setup:
Unclaimed feeders are (have to be done from inside the space):
- Piaware feeder
- Planefinder (?)
The antenna is located above the bar under the skylight.
How
Automatic Dependent Surveillance Broadcast (ADS-B) is a surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked. The information can be received by air traffic control ground stations as a replacement for secondary surveillance radar, as no interrogation signal is needed from the ground. It can also be received by other aircraft to provide situational awareness and allow self-separation. ADS–B is "automatic" in that it requires no pilot or external input. It is "dependent" in that it depends on data from the aircraft's navigation system. This signal is transmitted at 1090Mhz and 978Mhz.
The decoder software (Dump1090) takes in the raw data from the SDR and parses it, we are running the forked version made by Flightradar24, which means the feeder also sends data to Flightradar24. We are also feeding this data to Flightaware and Planefinder.
