GNSS Sim-3D Multipath Simulation Software

Page views：

Product overview

GNSS Sim-3D is a multipath simulation software developed based on satellite navigation technology and geographic information technology.It enables real-time calculation and reproduction of realistic multipath effects by leveraging 3D environmental models,receiver(or antenna)position and orientation,satellite orbits,and radio signal propagation models.

The software adopts a B/S(Browser/Server)architecture and uses the WebGL protocol to load and display 3D scene models.It also employs the WebSocket protocol for real-time communication,ensuring high responsiveness and real-time performance of the simulation.

GNSS Sim-3D Multipath Simulation Software

Functional advantage

Scene Editing

Supports adding,deleting,and freely rotating models in the 3D scene;allows editing of material coefficients of models with the 3D environment
Trajectory Editing

Enable automatic generation of target carrier trajectories by setting control points
Motion Control

Allows users to edit the movement speed of the carrier
Signal Visualization

Supports the visual display of direct line-of-sight signals,multipath reflected signals,refracted signals,and diffuse reflections signals.The display color of each signal type can be customized
Environmental Occlusion

Provides the ability to enable or disable environmental occlusion effects on navigation signals
Preset Typical Scenarios

The software includes built-in typical environments such as suburban areas,urban areas,highways,highway tunnels,airports,and anechoic chambers
Preset Typical Models

Comes with a library of typical 3D models such as buildings,vehicles,pedestrians,roads,and obstacles
Preset Typical Materials

Includes default materials such as metal,white walls,concrete walls,asphalt surfaces,steel plates,trees,grass,etc.,and supports custom material editing
Supports for External Imports

Supports importing of external 3D scenes and models.Supported formats include SKP,OBJ,3DS,FBX,etc
