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. What accessories are included with the CGI-830?

  The CGI-830 package includes an integrated GNSS/INS receiver, two GNSS antennas, a 4G antenna, data cables, and product packaging.

• 3. What data can the CGI-830 output?

  The CGI-830 features a high-performance GNSS module 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.

• 4. What post-processing does the CGI-830 support?

  The CGI-830 is equipped with a high-performance MEMS IMU and is fully compatible with NovAtel’s Inertial Explorer software through an optimized post-processing model.

• 5. Can the CGI-830 be installed in a car?

  Yes, the CGI-830 can be installed in a car. With CTCLIB2.0's multimodal adaptation function, it supports unique algorithm optimization for different vehicles. Before use, simply select the appropriate mode to meet the application requirements of various autonomous driving systems.

• 6. 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.

• 7. Can the CGI-830 be used for maritime applications?

  Yes, the CGI-830 includes an algorithm model designed for maritime use. It supports shipborne sensors such as DVL and USBL, and its heave correction algorithms meet the demands of both surface and underwater navigation and mapping
