Cleaner Measurements = Better Positions

Now that we’ve shown the benefits with ST’s own internal positioning engine (view the report here), the next step is to deliver those benefits to third-party positioning engines — the ones most automotive OEMs already use and trust in their platforms.

What S-GNSS Is — and What It Does for a Positioning Engine

At its simplest, S-GNSS Auto is software inside the GNSS receiver’s measurement engine. It looks at the incoming satellite signals, figures out which ones are truly coming direct from the satellite (Line-of-Sight) and which are reflections (multipath), and then strengthens the good ones while suppressing the bad.

The output format — codephase, Doppler, CN0 — stays exactly the same. The difference is that those numbers are now cleaner: more accurate, more reliable, and more representative of reality.

That reliability is the foundation of trust. A positioning engine (PE) can do a lot with sophisticated statistical methods to filter and weight the measurements it receives, but those methods are still limited by the quality of the raw inputs. Cleaner inputs mean the PE can work from a stronger starting point — and that builds trust in the final positioning solution.

Why This Matters for OEMs

The best GNSS products, and in fact most of automotive technology, are built on collaboration between different parts of the supply chain. At FocalPoint, we’ve started working with positioning engine suppliers to show how S-GNSS performs in combination with their solutions.

For OEMs, that means it’s becoming possible to see S-GNSS improvements with the PEs you already know and use. We want to show how your PE of choice (or interest) can improve its solution with the advantage of cleaner measurements.

Collaboration in action

Sometimes the PE supplier already has the right data to run tests. Sometimes we provide RF datasets — complete with ground truth — or run joint data collections in specific cities or on certain routes. In other cases, OEMs themselves handle the testing with our support.

The important part: these collaborations work best when we know what matters most to the OEM. If you’re an automotive manufacturer, tell us what PEs, which routes and what environments matter to you, and we can work with the right people to make sure that’s what gets tested.
