APRS Cursor-on-Target Gateway.

Project description

Screenshot of APRS points in ATAK-Div Developer Edition.

aprscot receives APRS Frames from APRS-IS and outputs them in as Cursor-on-Target (CoT) PLI, for use with CoT systems such as ATAK, WinTAK, RaptorX, et al. See for more information on the TAK program.

Currently supports APRS-IS and Location-type APRS messages, and sending to TCP CoT Hosts & TAK Servers.


The command-line daemon aprscot can be install from this source tree (A), or from the Python Package Index (PyPI) (B).

  1. To install from this source tree:

    $ git clone
    $ cd aprscot/
    $ python install
  2. To install from PyPI:

    $ pip install aprscot


The aprscot daemon has several runtime arguments:

$ aprscot --help
usage: aprscot [-h] -c CALLSIGN -C COT_HOST [-p PASSCODE] [-a APRS_HOST]
               [-f FILTER]

optional arguments:
  -h, --help            show this help message and exit
  -c CALLSIGN, --callsign CALLSIGN
                        APRS-IS Login Callsign
  -C COT_HOST, --cot_host COT_HOST
                        Cursor-on-Target Host or Host:Port
  -p PASSCODE, --passcode PASSCODE
                        APRS-IS Passcode
  -a APRS_HOST, --aprs_host APRS_HOST
                        APRS-IS Host (or Host:Port).
  -f FILTER, --filter FILTER
                        APRS-IS Filter, see:

For minimum operation, -c CALLSIGN & -C COT_HOST are required.

The following example forwards all APRS Frames within 50 meters of W2GMD-9’s last known location to the Cursor-on-Target host at port 4242 (TCP):

aprscot -c W2GMD-9 -C -f m/50

Example Cursor-on-Target Event

The aprscot daemon will output CoT XML Events similar to this example:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<event version="1.0" type="a-f-G-E-V-C" uid="APRS.W2GMD-1"
    time="2020-09-24T14:53:28.945221Z" start="2020-09-24T14:53:28.945221Z"
    stale="2020-09-24T15:53:28.945221Z" how="h-e">
   <point lat="38.51167" lon="-122.99883" hae="10" ce="10" le="10" />
