This is a Mode S, ADS-B, TIS-B and ADS-R decoding library for Java. It was forked from the OpenSky Network's (https://www.opensky-network.org) java-adsb library and refactored entirely to accommodate TIS-B and ADS-R.
It is based on these two references:
- ICAO Aeronautical Telecommunications Annex 10 Volume 4 (Surveillance Radar and Collision Avoidance Systems)
- RTCA DO-260B "Minimum Operational Performance Standards (MOPS) for 1090ES"
It supports the following Mode S downlink formats:
- DF 0: Short air-air ACAS
- DF 4: Short altitude reply
- DF 5: Short identify reply
- DF 11: All-call reply
- DF 16: Long air-air ACAS
- DF 17/18: Extended Squitter (see ADS-B formats below)
- DF 19: Military Extended Squitter
- DF 20: Comm-B altitude reply
- DF 21: Comm-B identify reply
- DF >24: Comm-D Extended Length Message
The following ADS-B formats are supported:
- BDS 0,5: Airborne position messages (including global and local CPR)
- BDS 0,6: Surface position messages (including global and local CPR)
- BDS 0,8: Identification messages
- BDS 0,9: Airborne velocity messages
- BDS 6,1: Aircraft status reports (emergency/priority, TCAS RA)
- BDS 6,2: Target state and status messages
- BDS 6,5: Operational status reports (airborne and surface)
The Comm-B registers, Comm-D data link and military ES are not parsed. Comm-B and D will follow at some point.
The formats are implemented according to RTCA DO-260B, i.e. ADS-B Version 2. The decoder properly takes care of older versions.
This is a Maven project. You can simply generate a jar file with mvn package.
All the output can afterwards be found in the target directory. There will
be two jar files
lib1090-VERSION.jarcontains lib1090, only.lib1090-VERSION-fat.jarincludes lib1090 and all its dependencies.
We have also published this project on Maven Central. Just include the following dependency in your project:
<dependency>
<groupId>de.sero-systems</groupId>
<artifactId>lib1090</artifactId>
<version>VERSION</version>
</dependency>
