oneNav’s unique design for a Pure L5 (i.e., L5/E5/B2) GNSS receiver offers significant advantages compared to a conventional L1-band or dual-frequency L1+L5 solutions. This is especially true in mobile device platforms. Beyond the significant cost and area benefits, increased accuracy, and immunity to multipath, a Pure L5 receiver offers clear advantages in terms of interference immunity to 2/3/4/5G and WiFi/Bluetooth onboard emissions. A detailed analysis of interference scenarios in mobile phones is presented. Harmonic and intermodulation products are considered for on board transmitters operating on present and future cellular modem bands in intraband LTE carrier aggregation (CA) and LTE-NR dual connectivity (ENDC) configurations and with 2.4GHz and 5GHz connectivity bands.
