The new GNSS platform improves positioning accuracy in urban environments

     U-blox announced the F10, the company's first dual-band GNSS platform that combines L1 and L5 bands, providing enhanced multipath resistance and meter-level positioning accuracy. The platform caters to urban transportation applications, including after-sales telematics and micro-transportation.

     Applications for precise positioning using GNSS receivers are increasing. However, current receivers still need to be fully functional in urban areas. In dense urban environments, where buildings or foliage can reflect satellite signals, GNSS receivers are needed to mitigate multipath effects. The L5 band's elasticity to these influences greatly improves positioning accuracy. Combined with the well-established L1 band, the L1/L5 dual-band GNSS receiver can provide a positioning accuracy of <2m (CEP50), while the positioning accuracy is about 4m in L1 band alone. The company's team has conducted driving tests in several urban areas, confirming considerable improvements over the GNSS L1 receiver.

     The f10 platform's firmware algorithm prioritizes L5-band signals in weak signal environments, ensuring reliable positioning accuracy even when paired with small antennas. The platform also offers protection level technology that provides real-time and reliable positioning accuracy estimation.

     When the cellular modem is very close to the GNSS receiver, it interferes with the receiver's reception. Some F10 module models (NEO-F10N, MAX-F10S, and MIA-F10Q) provide a powerful RF circuit that enables GNSS and cellular modems to operate without interference.

     The platform is pin-to-pin compatible with the previous u-blox M10 generation for easy migration. It also supports u-blox AssistNow, which provides real-time online A-GNSS service with global availability to reduce GNSS first repair time and power consumption.
