User Manual


AstSimulator is a surveillance sensor simulation tool.


It's possible to create a simulation scenario, add different types of flights and surveillance sensors into the scenario. When the simulation starts to run, it will simulate the flying of flights, and generate sensor output according to sensor characteristics.

The sensor output is in Eurocontrol ASTERIX format, which is industry de facto standard, and can be used by external tools and systems.

The original intention of AstSimulator is to be an useful tool to test air traffic control automation system or other similar system.


AstSimulator supports the following types of flights:

  • Random Flight

    A random flight will select a random route by itself in a predefined fly region, and fly in a random selected ground speed and level.

  • Orbit Flight

    An orbit flight will enter an orbit route around a specified center with a specified radius.

And supports the following types of sensors:

  • ADS-B

    Automatic dependent surveillance - broadcast (ADS-B) will receive broadcast from aircraft transponder, assemble and send out targer report.

During the simulation, it's possible to change the simulation speed, or pause it.

It's possible to check the output of selected sensor, in both raw format and decoded format.
