Multipath and signal obscuration are one of the main sources of error in GNSS receivers, with observed multipath error ranging from a few meters to hundreds of meters. Accounting for these factors is vital in all GNSS-enabled applications.
Sim3D is an innovative 3D modeling system that creates a realistic environment for the testing of multipath and obscuration effects. Simulated GNSS signals interact with fully customizable models and environments, giving a level of detail, control, and realism not available in other solutions.
