oneNav is the only single frequency L5 GNSS receiver on the market. L5-direct 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 GNSS receiver
Overview
Key Features
- L5 advantages without L1 limitations
- oneNav’s L5-direct 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.
- Multi-Constellation
- oneNav L5-direct works with the GPS, Beidou, Galileo, GLONASS and QZSS navigation satellite constellations, whose transmissions are globally interoperable.
- Simplified single frequency design
- oneNav doesn’t require the dual RF front end that hybrid L1/L5 receivers do. oneNav’s L5-direct receiver uses a single 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 one second TTFF.
- oneNav L5-direct 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 L5-direct receiver, oneNav’s Machine Learning models infer positions using RF pattern matching.
- oneNav L5-direct GNSS—flexible & scalable
- oneNav delivers its L5-direct 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.
