PacketRaven is a dashboard built to track high-altitude balloon flights from their location telemetry.

pip install packetraven

Installation

  1. install Python https://www.python.org/downloads/
  2. create a virtual environment so you don't pollute your system Python installation (or skip to step 3 if you don't care)
    pip install virtualenv
    virtualenv packetraven_env
    
  3. activate your new virtual environment
    • On Linux:
    source packetraven_env/bin/activate
    
    • On Windows native command prompt (cmd):
    .\packetraven_env\Scripts\activate.bat
    
    • On Windows PowerShell:
    .\packetraven_env\Scripts\activate.ps1
    
  4. install packetraven
    pip install packetraven

Command-line Examples

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

packetraven --tnc COM4

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

packetraven --apikey <api_key> --callsigns W3EAX-8,W3EAX-14

listen to a PostGIS database table:

packetraven --database <username>@<hostname>:5432/<database_name>/<table_name>

watch a text file for new lines containing raw APRS strings:

packetraven --tnc 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:

packetraven --tnc COM3 --callsigns W3EAX-8,W3EAX-14 --database <username>@<hostname>:5432/<database_name>/<table_name> --tunnel <ssh_username>@<hostname>:22

GUI Examples

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

packetraven --gui
packetraven --callsigns W3EAX-8,W3EAX-14 --apikey <api_key> --gui

Python API Examples

to retrieve packets directly from https://aprs.fi:

from packetraven import APRSfi

aprs_fi = APRSfi(
    callsigns=['W3EAX-8', 'W3EAX-12', 'KC3FXX', 'KC3ZRB'],
    api_key='<api_key>',  # enter your APRS.fi API key here - you can get one from https://aprs.fi/page/api
)

print(aprs_fi.packets)

or parse packets from a TNC sending parsed APRS over a USB connection:

from packetraven import SerialTNC

tnc = SerialTNC(
    serial_port='COM5',  # set to `'auto'` to connect to the first open serial port
)

print(tnc.packets)

or connect to a PostGreSQL database running PostGIS:

from packetraven import APRSDatabaseTable

table = APRSDatabaseTable(
    hostname='<hostname>:5432',
    database='<database_name>',
    table='packets',
    callsigns=['W3EAX-8', 'W3EAX-12', 'KC3FXX', 'KC3ZRB'],
    username='<username>',
    password='<password>',
    ssh_hostname=None,
    ssh_username=None,
    ssh_password=None,
)

print(table.packets)
