4D-NAVSIM simulation framework

4D-NAVSIM is an ATM/ATC/CNS simulator developed by Mobile Communications R&D Forschungs GmbH, Salzburg, in close co-operation with Paris Lodron University of Salzburg (PLUS) and 4D-Aerospace Research and Simulation GmbH, Salzburg, which allows to simulate European air traffic based on specific reference days (around 36.000 flights within 24 hours). 

Air traffic simulation is based either on:

  • Real air traffic (IFR flights) in the past for a reference day (e.g. peak day in summer)
  • Scheduled flight data in the past or near future for all airline, charter and cargo flights (as far as provided by air carriers)
  • Any individually defined air traffic scenario created by state of the art 4D-NAVSIM flightplan generator
  • Any defined validation exercise scenario
  • Recorded air traffic tracks provided in standard radar data format or multi-lateration
  • Recorded air traffic provided in any user defined data format
  • GPS based data from measurement flights

Real-Time & fast-time simulator

4D-NAVSIM can be used as real-time simulator and as fast-time simulator. It allows accurate simulation (i.e. runway-to-runway or gate-to-gate) which is based on realistic worldwide air traffic extracted from Eurocontrol/NM data, worldwide flight scheduled data, or any user flight plan data. Thereby, 4D-NAVSIM is using worldwide navigation data and considers aircraft performances, SID, Enroute (i.e. airway system, Great Circle, or 4D-trajectory), Arrival (STAR), Approach and Final Approach.

Long development history in numerous projects

As a high fidelity simulator, 4D-NAVSIM was used already in about 40 research projects for evaluating future digital aeronautical, both terrestrial and satellite based communication systems, SESAR 4D-trajectory concepts, validation and benefit assessment of weather impact on ATM/ATC, ATM performance, advanced Arrival Management (AMAN), Remotely Piloted Aircraft System (RPAS, drones) in segregated and non-segregated airspace, remote tower simulation, advanced airport operations and future air traffic controller training featuring both voice and CPDLC communications and decision support scenarios towards automated systems in the aerospace and railway domain
