The ZED-F9R from u-Blox is a Multi-Band GNSS Module that supports GPS/QZSS, GLONASS, Galileo and BeiDou constellations. It has an integrated inertial measurement unit (IMU) for RTK positioning which uses built-in algorithms to fuse the IMU data, GNSS measurements, wheel ticks, correction data, and vehicle dynamic models to provide optimal positioning accuracy. The module can receive signals from 4 GNSS satellites simultaneously in challenging environments, can accurately process multipath signals and operate well in covered areas.
The ZED-F9R has a cold start of 24 s, aided start of 4 s and reacquisition time of 2 s. It has a tracking and navigation sensitivity of -160 dBm, cold start sensitivity of -147 dBm and hot start sensitivity of -158 dBm. The module requires a DC supply of 2.7 -3.6 V and consumes 85 mA of current. It can be controlled via UART, USB, SPI and DDC interfaces.
The ZED-F9R has built-in TCXO, RTC, flash memory, 3D accelerometer, 3D gyroscope, diplexer and SAW filters. It supports RTCM or SPARTN-formatted corrections, enabling high precision navigation using internet or satellite data. This module is available in an LGA package that measures 17 x 22 x 2.4 mm with an antenna interface and is ideal for agricultural machinery, heavy trucks, low speed ground robotics, different classes of wheeled vehicles and professional applications.
