Patent Document 2 describes an apparatus for generating a trajectory of a receiver in a satellite navigation simulator. The apparatus includes an input unit for receiving position information of a receiver at latitude, longitude, and altitude and inputting information of a trajectory to be generated; Centered coordinate system having an X-axis, a Y-axis, and a Z-axis as the origin, and the coordinates of the first-order converted earth-centered fixed coordinate system are subjected to axial conversion so that the values of the X- and Y- A numerical value calculation unit for calculating the locus information to be generated using the local coordinate system and calculating an axial conversion value of the local coordinate system; And a re-conversion unit for re-converting the coordinates into the earth-centered fixed coordinate system using the calculated axial conversion values in the coordinate system.

The satellite navigation signal generating device provided in such a conventional satellite navigation system is excellent in signal generation own technology, but has a difficulty in allowing a user to use various simulation situations due to poor user interface function as a control unit for controlling a device.

Accordingly, a controller having a scenario editing function capable of precisely editing various generation situations available in the real world has been developed not only in the control unit but also in the control unit.

As shown in FIG. 8B, A name can be input in the jamming signal generation period, and the start and end points of the jamming signal or deception signal generation period are displayed on the electronic map as shown in Fig. 8C. As shown in FIG. 8D, it is possible to designate a plurality of jamming signal or deception signal generation sections, and to overlap the jamming signal or deception signal generation section, thereby generating a jamming signal or a deception signal generation section, A scenario can be edited to simultaneously generate a satellite navigation signal, a jamming signal, and a deception signal.

Since the Doppler update rate of the satellite navigation signal generator is 10 Hz, the elapsed time can be increased by 0.1 seconds.

If a list of coordinate-by-section coordinates is listed in order, a list of coordinates in units of several seconds (for example, 0.1 second) for the entire movement path is generated.

The flow of data in the process of scheduling a jamming signal is as shown in FIG. 13, and the flow of data in the process of scheduling a jamming signal is as shown in FIG. 14, The ending time is calculated by the same procedure shown in FIG. 15, and the distance between two points of the input jamming signal and the primed signal coordinates is calculated by repeating the calculation until the end of the travel path coordinate is reached.
