This Java 22 application connects to a MySQL database which contains ADS-B data collected from a receiver and antenna.
The display plots target echoes and track symbology. Multiple instances can be started with different altitude blocks. Each track shows the ICAO ID, US Registration, groundTrack, groundSpeed, vertical rate, and Mode 3 squawk.
It provides flashing displays for altitude conflict alerts, Ident, and Emergency squawks.
The sample shown shows a few aircraft, with blue meaning a climb, red meaning descent, and DIM meaning it hasn't received data for over a minute. After 90 seconds the track is dropped. The altitude in feet have an A prefix for below the Transition altitude, and F prefix above.
The ground speeds are in knots.
If the target changes its Mode-3 squawk, a flashing orange C pointer is shown. An Ident has a P, and an Emergency has an E.
The map was created using Jordans outline maker web page and using the satellite view:
