Understanding GNSS

An introduction to Global Navigation Satellite Systems and its impact

Global positioning principles

Services like Google Maps and Uber having become part of our everyday lives. These services enable us to easily and efficiently navigate our way from A to B, safely. They underpin our transport and logistics networks, are critical for our emergency services and will continue to fuel transformative change such as in autonomy.

But how do they actually work?

In simple terms, GPS systems rely on something called ‘GNSS’ – or Global Navigation Satellite Systems, to be precise – to determine the positioning, navigation and timing data relied upon by virtually every consumer with a smartphone and commercial business with a digital presence.

Why isn’t the blue dot where it should be?

Despite being the current solution to the world’s positioning requirements, the accuracy and sensitivity of most GNSS receivers are limited by decade-old concepts and are still very susceptible to occlusion and multipath interference.

GNSS performs poorly in cities because signals are blocked or reflected off buildings

The reflected signals dominate or interfere with the direct line-of-sight (LOS) signals

Receivers struggle to acquire very weak LOS signals from the noise (e.g. through foliage)

Adding GNSS constellations and frequency bands does not solve the problem

As cities become more built up, and economies demand more from location-based services, the impact of poor GNSS receiver signals with only will only get worse.

That’s why we founded FocalPoint.

Making devices more accurate, reliable and secure, with Supercorrelation™

FocalPoint develops groundbreaking technology that sets a new performance standard for location-dependent devices including smartphones, wearables and vehicles.

We use advanced physics and machine learning to significantly improve accuracy, reliability and energy consumption of standard GNSS receivers, with no additional hardware or infrastructure required.

Our groundbreaking Supercorrelation™ technology will change the capability of every GNSS-dependent device, system, business and individual user, across the billions of  devices shipped every year.
