Usage

PacketRaven reads a configuration file to determine which connections to set up, how to parse your packets, which callsigns to filter, etc.

packetraven /path/to/config.yaml

The configuration is in YAML format. Here is an example configuration:

# config.yaml

callsigns:
    - W3EAX-9
    - W3EAX-11
    - W3EAX-12

time:
    start: 2022-03-05
    end: 2022-03-06
    interval: 30

output:
    filename: ns110.geojson

log:
    filename: ns110.log

packets:
    aprs_fi:
        api_key: 123456.abcdefhijklmnop
    text:
        locations:
            - /dev/ttyUSB0
            - ~/packets.txt
    database:
        hostname: localhost
        port: 5432
        database: nearspace
        table: ns110
        username: user1
        password: password1
        tunnel:
            hostname: bpp.umd.edu
            port: 22

        location:
            - -78.4987
            - 40.0157
        time: 2022-03-05 10:36:00
    profile:
        ascent_rate: 6.5
        burst_altitude: 25000
        sea_level_descent_rate: 9
    output:
        filename: ns110_prediction.geojson

start the graphical user interface (GUI)

to start the GUI, add --gui to any packetraven command

packetraven --gui
packetraven config.yaml --gui

Examples

listen to a TNC sending raw APRS strings over USB port COM4

# config.yaml

packets:
    text:
        locations:
            - COM4

you can also set the location to auto to try the first open USB port

# config.yaml

packets:
    text:
        locations:
            - auto

listen to APRS.fi, watching specific callsigns

you need an API key to connect to APRS.fi; you can get one from https://aprs.fi/page/api

# config.yaml

callsigns:
    - W3EAX-8
    - W3EAX-14

packets:
    aprs_fi:
        api_key: 123456.abcdefhijklmnop

listen to a PostGIS database table

# config.yaml

callsigns:
    - W3EAX-8
    - W3EAX-14

packets:
    database:
        hostname: bpp.umd.edu
        port: 5432
        database: nearspace
        table: ns110
        username: user1
        password: password1

watch text file(s) for new lines containing raw APRS strings

# config.yaml

packets:
    text:
        locations:
            - http://bpp.umd.edu/archives/Launches/NS-95_2020-11-07/APRS/W3EAX-10/W3EAX-10_raw_NS95.txt
            - http://bpp.umd.edu/archives/Launches/NS-95_2020-11-07/APRS/W3EAX-11/W3EAX-11_raw_NS95.txt

listen to a TNC on COM3, watching specific callsigns, and synchronize new packets with a database table via SSH tunnel

# config.yaml

callsigns:
    - W3EAX-8
    - W3EAX-14

packets:
    text:
        locations:
            - COM3
    database:
        hostname: localhost
        port: 5432
        database: nearspace
        table: ns110
        username: user1
        password: password1
        tunnel:
            hostname: bpp.umd.edu
            port: 22
            username: user1
            password: password2
