Mitigating Multipath effects: Real-time S-GNSS Receiver

Register for Final Presentation of the NAVISP EL2-119 Project: "Real-time S-GNSS Receiver"

Mitigating the effects of multipath interference and non-line-of-sight (NLOS) signals, particularly in urban environments, is one of the biggest challenges in radio positioning.

The Supercorrelation™ technology developed by Focal Point Positioning solves this problem by performing long coherent integration while the receiver’s antenna undergoes complex motion, boosting sensitivity towards the line-of-sight (LOS) signals while suppressing unwanted signals. 

In this project we developed a complete S-GNSS® receiver to demonstrate the performance benefits of Supercorrelation in Global Navigation Satellite System (GNSS) positioning. 

Deep urban driving trials, conducted using our bespoke hardware-plus-software trials platform, showcase the accuracy improvements in both the measurement (pseudorange and Doppler) and position domains (position and velocity).  Also demonstrated is our Skyscan technology, which enables signals received via a single-element antenna to be decomposed into LOS and NLOS components and mapped onto an azimuth and elevation plot, thereby revealing the signal strength and directions-of-arrival of the various signal components.

The NAVISP Project EL2-119 “Real-time S-GNSS Receiver" was funded by NAVISP Element 2, which is devoted to supporting competitiveness of European industries.
