DEEPLY COUPLED NAVIGATION ENGINE
Empowered with deeply coupled GNSS/INS navigation engine, X2 fuses deeply the IMU and RTK solution and observation pre-processing, providing real-time high-precision navigation results such as position, velocity and 3D attitude.
DUAL ANTENNA POSITIONING AND HEADING
The GNSS signals received by dual antennas can independently provide accurate position and attitude, further improving the robustness and availability of the GNSS/INS system.
SCALABILITY
Software scalability: customers can upgrade software firmware for free within three years; Hardware scalability: provide multiple interfaces, including Ethernet, serial, etc., also provide EVENT I/O synchronization and can work with other sensors (such as LIDAR, SLAM, etc.).
HIGH RELIABILITY
X2 can work well in demanding environments, and maintain reliable and stable positioning performance for a period of time when satellite signals are lost or interfered.
SCENE OPTIMIZATION
Optimized for in-vehicle applications: based on vehicle characteristics modeling, it can tackle with the most challenging environments such as urban road canyon and satellite signal interference, providing continuous, stable and reliable real-time high-precision positioning services for intelligent vehicle application.
PRECISE POINT POSITIONING (PPP)
Capable to calculate the position with the phase and pseudorange observations of a single GNSS receiver, no base station or post processing is needed, so that any user, no matter where they are in the world, can get decimeter-level or even centimeter-level positioning accuracy.
