In the option None, the Rsimu defines the circular area where the ILTs are spread. In this case, the relative location of IT-VR is calculated as follows:
- Trial of the path distance factor according to the scenario setting for the VR-IT path;
- Calculation of the absolute distance as a product of the user-defined simulation radius (constant value that you define in VLR-ILT path settings) and the above path distance factor;
- Trial of the path azimuth angle according to the relevant distribution set in the scenario for VR-IT path. Based on that relative angle-distance information, the absolute positions could be established with reference to one known position (usually VR in this case).
