Frequently Asked Questions

S-GNSS

What is S-GNSS® Auto?

S-GNSS® Auto is a software upgrade for GNSS receivers. Working directly from the chip, it boosts GNSS accuracy and reliability, enabling safer navigation and autonomy in urban areas and forest roads.

What environments does S-GNSS® Auto improve performance in?

It significantly improves GNSS accuracy in urban canyons, dense foliage, and other multipath-heavy environments.

Does S-GNSS® Auto improve GNSS security?

Yes. It rejects spoofed and non-line-of-sight signals, helping vehicles defend against malicious attacks.

What kind of accuracy improvements does S-GNSS® Auto deliver?

In latest trials, S-GNSS Auto has demonstrated 3x improvement in position accuracy and up to 4x improvement in measurement accuracy in multipath environments.

How does S-GNSS® Auto act like a “virtual antenna upgrade”?

It boosts the sensitivity of the receiver, compensating for suboptimal antenna designs, restoring performance without hardware changes.

Can S-GNSS® Auto be deployed to cars already on the road?

Yes. It can be distributed over-the-air by OEMs and Tier-1 suppliers, just like any other firmware update.

Does S-GNSS® Auto require new hardware?

No. It’s a software-only solution, delivered as a firmware upgrade to existing GNSS chipsets.

How does Supercorrelation™ work?

It performs unusually long coherent integrations (up to 1–5 seconds) with motion compensation, allowing separation of line-of-sight signals from reflections.
