The PureL5 Customer Evaluation System is being tested by California and Chinese companies

OneNav has announced the commercial availability of its pureL5 GNSS digital IP core.

The pureL5 digital IP core’s architecture enables it to directly acquire and track L5 signals from GPS, Galileo, BeiDou, QZSS and GLONASS without any L1 aiding. This eliminates the entire L1 RF chain, saves space on the printed circuit board, and simplifies the RF front-end and antenna subsystem in smartphones, wearables and trackers.

The pureL5 digital IP core’s massively parallel array processor searches the entire 1-millisecond L5 code space in parallel, delivering 1 second time to first fix (TTFF). The pureL5 digital IP core is 0.28mm2 in the 3-nm semiconductor process and consumes 4.7 mW of power in 1-Hz tracking mode.

OneNav has delivered the pureL5 digital IP core register-transfer level (RTL) to its first system-on-chip (SOC) customer. IP core RTL verification and physical implementation are complete, and oneNav’s SOC licensee will tape out in the first quarter of this year. The pureL5 digital IP core RTL is available for customer licensing and shipment now.

Customer Evaluation System. OneNav’s pureL5 Customer Evaluation System is being tested by companies in California and China. The system is available for smartphone and wearable OEMs and SOC providers who want to evaluate oneNav’s pureL5 in the field and the lab.
