Even without sensor augmentation, oneNav’s pureL5 much more accurate in urban testing
Sunnyvale, California, 26 July 2022
Silicon Valley, California-based technology company oneNav today shared side-by-side test results comparing its pureL5 GNSS receiver customer evaluation system (CES) to a market-leading Android smartwatch. In a challenging urban environment, oneNav averaged 6x better accuracy than the smartwatch. Both units used commercial wearables antennae for testing. While the oneNav CES used only GNSS measurements, the smartwatch GNSS results were augmented by inertial sensors. At the 95th percentile, the pureL5 unit reported about 8-meter accuracy compared to nearly 29-meter accuracy for the Android smartwatch. pureL5 accuracy includes AI/machine learning algorithms which improve the system over time.
One question frequently posed to oneNav folks is, “why did you even think to create a company around single-frequency L5, something which most everyone else thought wasn’t even possible?” It’s true that, while L5/E5/B2 signal availability is increasing, the only commercial implementations have been suboptimal technically awkward dual frequency L1/L5 solutions. “The L5 signal is more accurate and reliable than L1, it has higher power and wider bandwidth, and it is less jammable,” noted Steve Poizner, co-founder and CEO of oneNav. “We looked at where the market is heading, with the wearables and tracking device markets exploding and the demand for higher accuracy increasing, and we asked, ‘why keep two bands/two RF chains/two antennas when you can get superior performance with just L5?’” said Poizner.
