1.PROGRAMME OUTLINE:
      In the modern war, the navigation technology has the irreplaceable status, the recent several local wars all indicated: “The navigation war”has become the modern war the important symbol. The 1998 war in Bosnia and Herzegovina, the 2001 U.S. military campaign in Afghanistan, and the 2003 U.S. British war in Iraq all used the precision-guided munition as their primary weapon. Various satellite navigation systems and integrated navigation systems based on modern navigation technology also play an important role in the navigation of space shuttle, spacecraft, ship and submarine. The aim of this project is to set up the simulation environment of navigation equipment laboratory test and verification, and to set up the database of simulation experiment.

2.PROGRAMME DESCRIPTION:

  2.2.Module introduction
        2.2.1  Navigation platform simulation subsystem
        Navigation Platform Simulation sub-system mainly simulates the air, water, underwater and land with navigation equipment on the platform, navigation information display module.

        2.2.2  Branch of Navigation Simulation Deduction and 3D visualization
      The Integrated Navigation Simulation and 3D visualization is composed of simulation operation control, navigation scenario inference, navigation situation display, simulation data recording and playback, and integrated battlefield environment, the functions of scenario design, scenario inference, Operation Control of Simulation System and visualization of navigation situation are completed, and the record and playback of simulation data are provided.

        2.2.3  Hardware-in-the-loop simulation subsystem of navigation system
       The hardware-in-the-loop simulation subsystem of navigation system provides hardware-in-the-loop simulation environment, integrates navigation equipment, and realizes the joint simulation of digital simulation system and hardware-in-the-loop simulation system.

        2.2.4 Distributed real-time database
        This scheme establishes a set of distributed real-time database based on DDS. The data source includes real navigation equipment, navigation simulator and other navigation data generating software. The database can be used for many kinds of navigation applications, provide the necessary conditions for testing and validation of the Navigation System Laboratory.

3.Technical characteristics
        1. As one of the important airborne systems, the navigation system provides the necessary guarantee for the flight safety and the completion of various flight tasks through the simulation and verification of the optimized environment.

        2. The huge market space of Beidou navigation makes the verification assistance of navigation system more necessary.

        3. Through the simulation and verification of navigation system, the accuracy, stability and reliability of navigation system for the whole world can be improved.

4.Application scenario
In the lab, WE SIMULATE TWO MODES:
        1）Each of these platforms carries one or more navigation devices, navigation and track data are gathered to the remote Central Command and control hall for display and scheduling.

        2）A motion platform carries several navigation devices, navigation data through its own carrying processing equipment/computer operations, data supply its own navigation, decision-making.
