Backup voltage supplies the real-time clock and battery-backed RAM and enables all relevant data to be saved in the backup RAM to allow a hot or warm start later. In the case of the main supply failure, the module can use a backup supply voltage from a connected battery. The USB port can be used as a power supply if you need the Click board™ to be a standalone device. The USB interface, compatible with the USB version 2.0 FS (Full Speed, 12 Mbit/s), can be used for communication as an alternative to the UART. If the jumper labeled as SFBT is populated and the SAFEBOOT pin is low at Power-Up, the receiver starts in safe boot mode and GNSS operation is disabled. The receiver also can enter a safe boot mode. In the default state, the jumper labeled as DSEL is unpopulated. When selecting the SPI communication, with the correct selection of the COMM SEL jumper, it is necessary to set the jumper to DSEL to configure the interface pins as SPI. The interface selection between UART/SPI can be performed by positioning SMD jumpers labeled as COMM SEL to an appropriate position.
GNSS RTK Click communicates with MCU using the UART interface at 9600 bps as its default communication protocol with the option for the users to use other interfaces such as SPI and I2C if they want to configure the module and write the library by themselves. It also ensures the security of positioning and navigation information by using secure interfaces and advanced jamming and spoofing detection technologies. The ZED-F9P comes with built-in support for standard RTCM corrections, routed on the additional header, unpopulated by default, available as an optional stand-alone RTCM input interface that can not be used as a host interface. Receiving more satellite signals at any given time maximizes the availability of centimeter-level accuracy even in challenging environments such as in cities. The combination of GNSS signals from multiple frequency bands (L1/L2/L5) and RTK technology allows the ZED-F9P to achieve centimeter-level accuracy in seconds.
100 MHZ CLOCK MINI ZED PLUS
Thanks to the multi-band RF front-end architecture, all four major GNSS constellations (GPS, GLONASS, Galileo, and BeiDou) plus SBAS and QZSS satellites can be received concurrently. This GNSS receiver can receive and track multiple GNSS constellations. GNSS RTK Click is based on the ZED-F9P, a multi-band GNSS module with integrated multi-band RTK technology offering centimeter-level accuracy from U-blox. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
100 MHZ CLOCK MINI ZED SOFTWARE
GNSS RTK Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
This Click board™ is suitable for machine control, ground robotic vehicles, and high precision unmanned aerial vehicles (UAV) applications. It also includes moving base support, allowing both base and rover to move while computing a centimeter-level accurate position between them. This module concurrently uses GNSS signals from all four GNSS constellations (GPS, GLONASS, Galileo, and BeiDou), and provides multi-band RTK with fast convergence times, reliable performance, and easy integration. This board features the ZED-F9P, a multi-band GNSS module with integrated multi-band Real Time Kinematics (RTK) technology offering centimeter-level accuracy from U-blox. GNSS RTK Click is a compact add-on board used to enhance the precision of position data derived from satellite-based positioning systems.
