The ZED-F9L from u-blox is an automotive grade multi-band GNSS dead reckoning module that supports L1/L5 bands. It is designed to provide reliable positioning for telematics and V2X applications. This module is based on the u-blox F9 GNSS platform which provides continuous sub-meter-level positioning accuracy with SBAS for challenging automotive use cases, including motorbike applications. It supports BeiDou, Galileo, GLONASS, GPS/QZSS constellations, and simultaneous tracking of L1/L5-band signals and 6 GNSS constellations, including NavIC.
The ZED-F9L has a built-in TCXO, RTC, flash memory, 3D accelerometer, 3D gyroscope, diplexer, and SAW filters. It has integrated IMU sensors along with sophisticated built-in algorithms which fuse GNSS measurements, IMU data, wheel ticks, and vehicle dynamics resulting in reliable positioning and attitude even when GNSS services are unavailable. This module can address issues such as latency constraints, RF front-end design issues, or dead reckoning algorithm integration. It utilizes u-blox position engine that incorporates a dependable protection level output and advanced security features including sensor-based anti-spoofing and anti-jamming techniques.
This GNSS module has a cold start of 24 s, aided start of 4 s, and a reacquisition time of 2 s. It has a tracking and navigation sensitivity of -160 dBm, a cold start sensitivity of -147 dBm, and a hot start sensitivity of -158 dBm. The module requires a DC supply from 2.7 to 3.6 V and consumes 85 mA of current. It has an operating temperature range from -40°C to +105°C and qualification tests have been performed as stipulated in the AEC-Q104 standard. The ZED-F9L is available in a 54-pin LGA package that measures 17.0 x 22.0 x 2.4 mm and can be controlled via UART, USB, SPI, and DDC/I2C interfaces.
