Bynav Alita GNSS Baseband ASIC Chipset
Alita is launched based on our extensive applications of mature FPGA solutions. Alita can track up to 72 satellites simultaneously and support BDS-3 signals. Integrated multi-sensor fusion interface supports 4-channel frequency-variable output and synchronization signal of the EVENT input. The synchronization accuracy is 20ns, and it can be precisely synchronized with other sensors such as LiDAR, INS and camera.

Description
Core Technology
1）Vector tracking loop. Achieve better performance in anti-jamming and anti-spoofing with multi-satellite multi-frequency joint tracking.
2）Multi-correlator based multipath suppression technique. Multi-correlator based parallel correlation methods suppress multipath effect where GNSS signal is reflected off buildings in urban environment, and improve the quality of GNSS observation data.
3）Deeply integrated navigation. Support external input inertial navigation information to assist signal tracking, and provide more robust and accurate observation data in harsh environment.
4）Signal quality monitoring. Monitor real-time tracking loop performance, output the accuracy of GNSS observation.
