FocalPoint Supercorrelation®

Making devices more accurate, reliable and secure

Award-winning, patented technology for enhanced GNSS reliability and accuracy in tough environments

Supercorrelation® is a patented, chipset-level software that improves the accuracy and reliability of GNSS receivers, revolutionising the positioning ability of vehicles, mobiles and wearables in challenging environments.

Its unique ability to discriminate the angle-of-arrival of satellite signals allows GNSS receivers to focus on the line-of-sight signals, ignoring all others, without the need for high-cost antennas.

With Supercorrelation, OEMs, chipset makers, and location-based service providers can build groundbreaking technologies that make a tangible difference to everyday users.

Higher accuracy

Supercorrelation mitigates the degradation in accuracy caused by multipath in urban areas, forested roads, and highways with sound walls.

Greater sensitivity

Supercorrelation boosts GNSS receiver sensitivity radio signals by up to 10 dB, optimising the performance of hidden antennas and maintaining location tracking when signals are attenuated.

Improved reliability

Supercorrelation makes GNSS more reliable by filtering out reflected and fake signals, so position estimates remain accurate and trustworthy.

Supercorrelation explained

As the foundational technology that enables our S-GNSS® product, Supercorrelation is designed for the modern system-on-a-chip silicon architecture used by all consumer GNSS receivers. It provides a highly accessible and cost-effective solution to improving GNSS receiver reliability, directly from the chip.

It requires no extra hardware or infrastructure and fits into existing architecture as a software upgrade.

How it works

By removing the effects of reflected signals and multipath interference – the biggest sources of error in urban canyons – it allows metre-level positioning to be maintained on consumer devices in the most challenging signal environments.

Allows the receiver to ignore reflected signals

Ignores fake, ‘spoofed’ signals, building resilience to spoofing attacks

No extra hardware or infrastructure is required

What's unique about Supercorrelation?

Whilst GNSS has remarkable capabilities, one of its most significant limitations is multipath interference caused by signals bouncing off buildings, trees, or other obstacles before reaching the GNSS receiver. This leads to inaccuracies in positioning and timing measurements, resulting in errors in determining the user’s position.

Supercorrelation is the only software-based GNSS technology capable of determining the arrival angle of signals, enabling line-of-sight determination and the removal of non-line-of-sight (NLOS) signals from the positioning solution.

Supercorrelation improves accuracy by overcoming the challenges of multipath interference. It also enhances security by identifying and rejecting the external radio signals that can spoof traditional GNSS setups.
