OneNav is sharing side-by-side test results comparing its pureL5 GNSS receiver customer evaluation system to a leading Android smartwatch.
OneNav is a Silicon Valley, California-based technology company designed to power high-performance positioning for location-dependent mobile services.
In a challenging urban environment, oneNav averaged six times better accuracy than the smartwatch. Both units used commercial-wearable antennas for testing. While the oneNav system used only GNSS measurements, the smartwatch GNSS results were augmented by inertial sensors.
At the 95th percentile, the pureL5 unit reported 8-meter accuracy compared to nearly 29-meter accuracy for the smartwatch; pureL5 accuracy includes artificial intelligence/machine learning algorithms that improve the system over time.
“The L5 signal is more accurate and reliable than L1, it has higher power and wider bandwidth, and it is less jammable,” said 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?’”
The oneNav team comprises top GNSS experts from Qualcomm, Apple, Intel, SnapTrack, SiRF, Trimble and eRide who have decades of GNSS and mobile industry experience. The team has expertise in GNSS system architecture, multipath mitigation, signal processing, ASIC design and AI/machine learning, and collectively has filed more than 300 career GNSS patents.
