4. MLAT

MLAT is short for Multilateration. MLAT enables us to calculate the position of a plane when three or more mlat enabled stations are in reach. Many smaller aircrafts are not equipped to send the position data on their own, this is where MLAT jumps in. The MLAT client is easy to install and does not interfere with any other MLAT Client you may already have installed. We really appreciate you installing MLAT on your ADS-B station.

If you didn't already, add our package repository first, as shown in the Install Chapter

Install the mlat-client package

sudo apt install mlat-client-sdrmap

Configure the mlat-client package

• please edit the configuration with sudo nano /etc/default/mlat-client-sdrmap manually

Configuration

• Edit your stationname and password which we sent you via e-mail, seperated by a ':'

SERVER_USER="yourstationname:thepasswordwesentyou"

• Edit latitude, longitude and altitude according to your location

LAT="51.00000"
LON="7.00000"
ALT="100"

• Everything else can be left unchanged
• The mlat-client communicates to the mlat server via stunnel4 which is automatically configured via the mlat-client-sdrmap package
• restart the service with sudo systemctl restart mlat-client-sdrmap

Done

• Now your station will feed MLAT to us. You can check the status of your station by selecting it on our map.
