Balloon payload telemetry over APRS
Project description
PacketRaven
PacketRaven is a front-end data aggregator / dashboard, designed to track the progress of high-altitude balloon payload flights via location telemetry.
pip install packetraven
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 ~\Desktop\aprs_packets.txt
listen to a TNC on COM3, watching specific callsigns, and synchronize new packets with a database table, using an SSH tunnel to connect:
packetraven --tnc COM3 -callsigns W3EAX-8,W3EAX-14 --database <username>@<hostname>:5432/<database_name>/<table_name> --tunnel <ssh_username>@<hostname>:22
Usage:
usage: packetraven [-h] [-c CALLSIGNS] [-k APIKEY] [-p TNC] [-d DATABASE] [-t TUNNEL] [-s START] [-e END] [-l LOG] [-o OUTPUT] [-i INTERVAL] [-g]
optional arguments:
-h, --help show this help message and exit
-c CALLSIGNS, --callsigns CALLSIGNS
comma-separated list of callsigns to track
-k APIKEY, --apikey APIKEY
API key from https://aprs.fi/page/api
-p TNC, --tnc TNC serial port or text file of TNC parsing APRS packets from analog audio to ASCII (set to `auto` to use the first open serial port)
-d DATABASE, --database DATABASE
PostGres database table `user@hostname:port/database/table`
-t TUNNEL, --tunnel TUNNEL
SSH tunnel `user@hostname:port`
-s START, --start START
start date / time, in any common date format
-e END, --end END end date / time, in any common date format
-l LOG, --log LOG path to log file to save log messages
-o OUTPUT, --output OUTPUT
path to output file to save packets
-i INTERVAL, --interval INTERVAL
seconds between each main loop (default: 10)
-g, --gui start the graphical interface
Python API:
to retrieve packets directly from https://aprs.fi:
from packetraven import APRSfiConnection
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
aprs_fi = APRSfiConnection(callsigns, api_key)
aprs_fi_packets = aprs_fi.packets
print(aprs_fi_packets)
or parse packets from a TNC sending parsed APRS over a USB connection:
from packetraven import SerialTNC
serial_port = 'COM5' # set to `'auto'` to connect to the first open serial port
tnc = SerialTNC(serial_port)
tnc_packets = tnc.packets
print(tnc_packets)
or connect to a PostGreSQL database running PostGIS:
from packetraven import APRSPacketDatabaseTable
callsigns = ['W3EAX-8', 'W3EAX-12', 'KC3FXX', 'KC3ZRB']
hostname = '<hostname>:5432'
database = '<database_name>'
table = 'packets'
username = '<username>'
password = '<password>'
# parameters for an SSH tunnel
ssh_hostname = None
ssh_username = None
ssh_password = None
table = APRSPacketDatabaseTable(hostname, database, table, callsigns,
username=username, password=password,
ssh_hostname=ssh_hostname, ssh_username=ssh_hostname, ssh_password=ssh_password)
table_packets = table.packets
print(table_packets)
