| GNSS 4 click PID MIKROE-2045 GNSS 4 click carries SAM-M8Q patch antenna module from u-blox. The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over I2C or UART interface. What is GNSS? GNSS stands for Global Navigation Satellite System, an umbrella term that describes both the United States GPS, the Russian GLONASS global positioning systems and European Galileo. module The SAM-M8Q module utilizes concurrent reception of up to three GNSS systems GPS/Galileo and GLONASS , recognizes multiple constellations simultaneously and provides outstanding positioning accuracy in scenarios where urban canyon or weak signals are involved. Patch antenna The GNSS patch antenna is RHCP right hand circular polarization and has a peak gain of 3 dBic. The patch antenna is insensitive to surroundings and has high tolerance against frequency shifts. Power management u-blox M8 technology offers a power-optimized architecture with built-in autonomous power saving functions to minimize power consumption at any given time. Furthermore, the receiver can be used in two operating modes Continuous mode for best performance or Power Save Mode for optimized power consumption. Good in hostile environments Thanks to all these features the SAM-M8Q module is good in GNSS-hostile environments indoor spaces, urban canyons when a street is flanked by buildings on both sides , etc. AssistNow service The u-blox SAM-M8Q module can also benefit from the u-blox AssistNow assistance service. The Online service provides GNSS broadcast parameters, e.g. ephemeris, almanac plus time or rough position to reduce the receiver’s time to first fix significantly and improve acquisition sensitivity. The extended validity of AssistNow Offline data up to 35 days and AssistNow Autonomous data up to 3 days provide faster acquisition after a long off time. How it works A constellation of satellites sends a continuous signal towards Earth. Onboard every satellite is an atomic clock, and all of them are synchronized, thanks to a reference time scale defined by the whole system. So, that the signals coming from the different satellites of the same constellation share the same reference time scale. The user wanting to use GNSS to determine its position must have an antenna that receives the signals coming from the satellites, and a receiver that translates these signals. The antenna position will be deduced from the measurements of the time delay between the emission time satellite and the reception time receiver for at least 4 signals coming from different satellites.
