Alice

GNSS SoC

The SoC has built-in REAL RTK positioning engine and DIST deep-coupled GNSS/INS navigation engine. SAIF（Smart Advanced Interference defense), the high-performance multiple interference suppresion technoloy, is also built in and capable of handling different interferences such as single-frequency, multitone, sweeping, pulse, narrowband with interference-signal ratio of 65 dB.

Designed for Excellence

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.
