Understanding Multipath and Obscuration

Multipath Obscuration 3d Simulation

Many modern applications and devices rely on continuous, accurate GNSS reception; from smartphones and wearables to advanced driver assistance systems (ADAS), energy grids and telecoms network infrastructure.

If the GNSS signal is impaired, the receiver risks outputting an inaccurate time or position, which could have a serious impact on the critical applications that rely on it.

Demand for accurate, continuous GNSS is especially high in cities, but urban environments pose many challenges for GNSS reception; notably signal obscuration and multipath. Receiver developers and integrators must understand how these effects impact the receiver in order to build in effective mitigation measures.
