Featuresthis is a precise centimeter level raspberry pi gnss hat based on zed-f9p. It provides features like multi-band rtk with fast convergence times, high update rate, moving base rtk mode support, concurrent reception of 4 gnss systems, augment positioning systems support, accurate & fast positioning with minor drifting, and outstanding ability for anti-spoofing & anti-jamming. By simply attaching it onto the pi, it is fairly easy to enable gnss capability for your raspberry pi. 1. Standard raspberry pi 40pin gpio extension header, supports raspberry pi series boards, jetson nano 2. Multi-band rtk with fast convergence times, centimeter level accuracy, high update rate 3. Support moving base rtk mode, enabling terminal precise navigation and centimeter level accuracy 4. Support concurrent receiving 4 gnss constellations gps, beidou, galileo and glonass , and still retains low power consumption 5. Augment systems support, including sbas, qzss, imes, d-gps, improving the positioning performance of service location 6.
