Explore our FAQs

• 1. What is the CTCLIB2.0 Algorithm?

  CTCLIB2.0 is CHCNAV's second-generation tightly coupled algorithm platform. It integrates inertial data from the INS with satellite positioning data from the GNSS to enhance positioning accuracy and reliability. This tightly coupled approach enables the system to deliver precise position and velocity information, even when GNSS signals are weak or lost, improving navigation performance in challenging environments. After extensive testing over millions of kilometers, CTCLIB2.0 offers a higher ambiguity resolution rate, smoother trajectories, and more reliable positioning compared to loosely coupled algorithms.

• 2. Can the CGI-230 be installed in a car?

  Yes, the CGI-230 can be installed in a car. With CTCLIB2.0's multimodal adaptation function, it supports unique algorithm optimization for different platforms. Before use, simply select the appropriate mode to meet the application requirements of various autonomous driving systems.

• 3. How is it used in ADAS applications?

  GNSS/INS systems provide highly accurate position, attitude, velocity, and time data, forming the basis for vehicle navigation and ADAS operation. This data supports functions like autonomous driving, lane keeping, and automatic emergency braking, serving as a reliable foundation for system optimization.

• 4. Which data output can I choose with the CGI-230?

  The CGI-230 features a high-performance GNSS chip and IMU, providing advanced tightly coupled algorithms and enhanced POS post-processing capabilities. CHCNAV offers custom protocols such as $GPCHCX and $HCINSPVAZCB, which deliver accurate real-time or post-processed information on position, attitude, velocity, and time.

• 5. What accessories are included with the CGI-230?

  The CGI-230 package includes an integrated GNSS/INS receiver, two GNSS antennas, data cables, and product packaging.

• 6. How to configure the CGI-230?

  CGI-230 is configured and queried by commands that can be sent via serial or network interface. The device supports multiple command input and multiple command detection.
