Today's consumers and fitness enthusiasts expect more from their wearables.
But when devices miscalculate location by tens or hundreds of meters, it leads to distorted route maps and unreliable distance tracking. In a competitive and growing wearables market, OEMs and chipmakers must raise the bar on GNSS accuracy. Improving the quality of GNSS data is essential to power the fitness apps and features that users rely on—and to deliver the accurate insights they expect.
Enhancing GNSS accuracy for today's sports wearables
FocalPoint’s S-GNSS® Wear software boosts GNSS receiver performance to improve the accuracy and integrity of any sports wearable.
S-GNSS® Wear provides OEMs, chip makers, and other service partners with a highly accessible and cost-effective solution to improving GNSS receiver reliability, directly from the chip.
Higher accuracy
S-GNSS Wear improves GNSS accuracy and reliability, which means fitness trackers present a more accurate picture of the distance travelled and the corresponding line on the map.
Greater sensitivity
Stronger signal performance even under trees or constrained antennas, with up to 10 dB boost in sensitivity to reduce signal dropouts.
Better Experiences
Supercorrelation™ enables S-GNSS® Wear to acquire a true location signal faster than standard GNSS, so your device is ready when you are.
How does S-GNSS® Wear work?
S-GNSS® Wear is a software upgrade for existing GNSS receivers that operates in the measurement domain. It combines our patented Supercorrelation™ technology and our human motion modelling technology to mitigate the degradation in accuracy caused by signal reflections and attenuation. It works by:
Boosting line-of-sight signals
S-GNSS enables the receiver to lock onto the line-of-sight signal, while ignoring all others. By improving receiver sensitivity, S-GNSS optimises the performance of concealed antennas and maintains accurate tracking under foliage.
Attenuating non-line-of-sight signals
By identifying and eliminating inaccurate signals, S-GNSS mitigates the effects of multipath interference, and helps to protect against spoofing attacks.
Supercorrelation™ uses a combination of machine learning, signal processing and sensor fusion techniques to tackle the challenge of accurate pedestrian navigation. By integrating and analysing data from various sensors, it ensures accurate tracking and guidance for individuals, whether they are walking through crowded urban environments or exploring unfamiliar outdoor areas. This results in enhanced user experiences for applications such as location-based services, and personal safety, ensuring that users navigate with confidence.
