oneNav is the only Mobile GNSS receiver on the market that uses a Pure L5 wideband receive chain, and enhances urban canyon performance with artificial intelligence
L5 advantages without L1 limitations
oneNav’s Pure L5 Mobile GNSS receiver leverages all the benefits of L5. oneNav acquires L5 directly, and tracks on L5, utilizing the full 50MHz of data available. Wideband (dual sideband) signal processing enables higher precision and better multipath resolution than existing single sideband receivers.
oneNav Pure L5 works with the GPS, Beidou, Galileo and QZSS navigation satellite constellations, whose transmissions are globally interoperable.
Simplified single frequency design
oneNav doesn’t require the dual band RF front end that hybrid L1/L5 receivers do. oneNav’s Pure L5 receiver uses a single band RF chain to receive wideband L5 signals, enabling OEMs to reduce their RF footprint, power consumption and cost.
oneNav’s breakthrough acquisition engine architecture
Direct L5 acquisition is challenging because L5 has much more information to decode. Conventional L1 receivers cannot directly acquire the L5 signal. oneNav has invented a massively parallel signal processing engine—a GPU for GNSS—that can directly acquire L5 with sub-second TTFF.

oneNav Pure L5 GNSS uses AI smarts to exploit multipath
Multipath, which is prevalent in urban environments, is the greatest source of GNSS position errors. oneNav uses AI to tackle multipath errors, utilizing all GNSS signals, including multipath signals, to get the very best accuracy. By combining unique channel characteristics from the oneNav Pure L5 receiver and other physical environment data, oneNav’s Machine Learning models infer positions using RF pattern matching.
