Based on advanced FPGA technology, the Alita GNSS chipset can track up to 72 satellites simultaneously, supporting the full range of constellations and frequencies including BDS-3 . With a synchronized accuracy of 20 ns, Alita can be seamlessly integrated with other sensors such as LiDAR scanners and cameras, and also supports external INS for navigation aiding during GNSS outages and other challenging conditions.
The system's multipath suppression technologies make it ideal for integration into robotic systems operating in urban environments and built-up areas, and signal quality and tracking loop performance can be monitored in real time. Thanks to state-of-the-art tracking, Alita also provides excellent anti-jamming and anti-spoofing performance.
