scanning software for ADS-B / ModeS a.k.a. airstrik 2.0
PyAerial is the successor to the now archived airstrik.py. It has achieved full feature parity and more, offering ways to do everything its predecessor could, but better.
PyAerial will scan for nearby planes using the ModeS/ADS-B protocol and provide an early-warning system for planes / helicopters that enter user-defined geofences, as well as programmable actions for the program to take (e.g. sending a POST request with data about the event or communicating with a Kafka server)

| Configuration Option | What does it control? | constants.py variable |
|---|---|---|
general |
Contains options relative to the entire program's scope that didn't fit anywhere else. | CONFIG_GENERAL |
general/mongodb |
The URI of the MongoDB instance to connect to if MongoDB is set as the method to save packets | CONFIG_GENERAL_MONGODB |
general/backdate_packets |
How many latitude/longitude packets back we look to perform a rough average when we calculate the heading. More = less variance, less = more variance. | CONFIG_GENERAL_BACKDATE |
general/remember_planes |
How many seconds since the last packet we should keep the plane in RAM before saving it to MongoDB | CONFIG_GENERAL_REMEMBER |
general/point_accuracy_threshold |
The degree accuracy used for determining if we should "chase" geofences. This is just an optimization. | CONFIG_GENERAL_PAT |
general/packet_method |
How the program should gather packets. Options: dump1090 or python. Dump1090 is significantly better, but requires dump1090 --raw --net to be running in another terminal. |
CONFIG_GENERAL_PACKET_METHOD |
general/status_message_top_planes |
How many of the "top planes" (most messages sent) to display in the status message sent every tick at the INFO logging level. | CONFIG_GENERAL_TOP_PLANES |
general/advanced_status |
Whether "advanced status" should be used. THis contains more data, with callsigns and packet type breakdowns. Example: INFO:Main:Tracking 5 planes. Top 5: AB5DE1/WUP31 (358, {5: 50, 3: 51, 0: 253, 1: 4}), A3965C/FFT3373 (216, {0: 115, 5: 50, 3: 46, 1: 5}), A95A1C/AAL2349 (177, {0: 143, 3: 19, 5: 14, 1: 1}), A80D40/JBU2929 (21, {0: 13, 5: 3, 3: 4, 1: 1}) |
CONFIG_GENERAL_ADVANCED_STATUS |
general/hz |
How many ticks per second to attempt. This is a maximum, not a minimum. | CONFIG_GENERAL_HZ |
home |
Contains the position of the ADS-B tracker. This is used to calculate globally accurate positions from the ADS-B packets. | CONFIG_HOME |
home/latitude |
The latitude of the ADS-B tracker | CONFIG_HOME_LATITUDE |
home/longitude |
The longitude of the ADS-B tracker | CONFIG_HOME_LONGITUDE |
zones |
Contains information about the geofences and their different warning levels | CONFIG_ZONES |
zones/[zone]/coordinates |
A list of lists containing the decimal lat/long coordinates that compose the geofence. | CONFIG_ZONES_COORDINATES |
zones/[zone]/levels |
Contains information about the levels of triggers the geofence has. | CONFIG_ZONES_LEVELS |
zones/[zone]/levels/[level]/category |
The category (information about how to save and alert) that this level of the geofence is tied to | CONFIG_ZONES_LEVELS_CATEGORY |
zones/[zone]/levels/[level]/time |
The maximum ETA the plane must have relative to the geofence to trigger this level. | CONFIG_ZONES_LEVELS_TIME |
categories |
Stores the categories (information for how alerts and saving works). Categories will only be used if they are put in at least one geofence | CONFIG_CATEGORIES |
categories/[category]/method |
Which method to use when alerting. Current options: print, kafka |
CONFIG_CAT_METHOD |
categories[category]/arguments |
If applicable, put arguments for the method in here. The only option is server for the kafka method currently. |
CONFIG_CAT_ALERT_ARGUMENTS |
categories/[category]/save |
Filters for saving to MongoDB. Existing methods: all, none, decimate(X), sdecimate(X,Y) |
CONFIG_CAT_SAVE |
categories/[category]/save/telemetry_method |
What method to use for the telemetry data (stuff received by the ADS-B receiver with no inference). | CONFIG_CAT_SAVE_TELEMETRY_METHOD |
categories/[category]/save/calculated_method |
What method to use for the calculated data (stuff we inferred from the ADS-B information, including corrected versions of telemetry data we already receive). | CONFIG_CAT_SAVE_CALCULATED_METHOD |
shapely # Other geographic math.
geopy # Some geographic math, mostly distance.
pymodes # some ADS-B decoding hex math
requests # hexdb.io's ICAO callsign API
pyrtlsdr # Pure-python ADS-B decoder
kafka-python # Using the Kafka alert method
pymongo # Interfacing with MongoDB
ruamel.yaml # For reading the configuration file
dump1090-fa is required for the dump1090 packet method to function. The command dump1090 --net --raw should work out-of-the-box. You can also broadcast raw ADSB messages over TCP port 30002 and the interface will also work.
Feel free to report any bugs or issues you find. Happy tracking!
