Solution
oneNav is the only single-frequency L5-band GNSS receiver on the market. pureL5 leverages all the advantages of L5 without the antenna subsystem complexity and doubling of RF front end area, cost, and power needed by dual frequency L1/L5 hybrids.

L5-BAND ADVANTAGES WITHOUT L1 LIMITATIONS
oneNav’s pureL5 GNSS receiver leverages all the benefits of L5-band signals. oneNav acquires these L5-band signals directly, and then tracks on them, utilizing the full 50MHz of data available. Wideband (dual sideband) signal processing enables higher precision and better multipath resolution than existing single sideband or dual-frequency hybrid receivers.
Multi-Constellation
oneNav pureL5 can work with the GPS, BeiDou, Galileo, GLONASS, and QZSS navigation satellite constellations, whose transmissions are globally interoperable.
SIMPLIFIED SINGLE-FREQUENCY DESIGN
oneNav’s pureL5 receiver uses a single RF chain to receive multi-constellation L5-band signals, enabling OEMs to reduce their RF footprint, power consumption, antenna subsystem complexity, and cost. oneNav doesn’t require the dual RF front end that hybrid L1/L5 receivers do.
ONENAV’S BREAKTHROUGH GNSS ACQUISITION RECEIVER
oneNav is the first company to develop a commercial, high performance, low cost L5 only GNSS acquisition and tracking solution, a massively parallel digital signal processor —a GPU for GNSS—that can directly acquire L5-band signals with one-second TTFF. Direct L5-band acquisition is challenging because L5 has much more information to decode and conventional L1 receivers do not have the processing resources to directly acquire the L5 signal.

High Performance
Simplified Design
Flexibility
oneNav pureL5 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/Machine Learning to tackle multipath errors, utilizing all GNSS signals, including multipath signals, to get the very best accuracy. By utilizing unique channel characteristics from the oneNav pureL5 receiver, oneNav’s Machine Learning models infer positions using RF pattern matching.
oneNav pureL5 GNSS—flexible & scalable
oneNav delivers its pureL5 GNSS receiver as a licensed IP core, giving designers the flexibility to integrate oneNav into modems, applications processors or other semiconductor devices. oneNav is a scalable receiver platform, enabling designers to implement whatever combination of performance and power consumption that their design requires.
