High Precision Combination Positioning System P-Box Test Solution
Program Introduction
HONGKE's GNSS simulator meets the test requirements of the fused positioning unit P-Box, providing a more efficient, reliable and flexible test platform and tool for testing and evaluating the performance of high-precision fused positioning P-Box modules for automotive V2X and autonomous driving applications.
Programmatic background
TCU (Telematics Control Unit) is an in-vehicle internet communication terminal, which is used to realize vehicle remote communication and remote service. With the continuous development of automatic driving technology, how to accurately obtain the vehicle positioning information becomes more and more important.
In an automated driving system, vehicles can obtain information about the surrounding environment and vehicle status through various types of sensors, and then process and plan based on the relevant data to make real-time decisions. Among them, GNSS positioning is the only sensor that can provide absolute position information, so GNSS positioning terminals play a key role. On the other hand, the inertial navigation system (IMU) measures and integrates accelerometer and gyroscope data to estimate and track the position, speed and direction of movement.
P-Box combines GNSS positioning with inertial navigation positioning to provide vehicles with accurate absolute position information and vehicle attitude information, thus enhancing the stability and reliability of the positioning results and supporting vehicle safety and intelligence, which is also an important component in the development of autonomous driving.
High Precision Combination Positioning System P-Box Test Solution
The P-Box test solution from Avision is designed to provide users with an easy-to-use, reliable and efficient way to conduct tests, while maintaining the flexibility needed for future technology evolution and application changes.
While providing true panoramic GNSS signals, HONGKE P-Box test solution also provides accurate 3-axis acceleration and orientation angle information within the same system, which can be used for back-end IMU test platforms or fusion algorithms control and testing. In addition, the system also supports RTK testing capability, which allows RTCM message verification on the original architecture without additional configuration and adjustment.

Synchronized IMU inertial combination navigation test capability
In addition to GNSS simulation, the Safran GNSS simulator also supports real-time IMU data generation. Users can set up the Skydel GNSS simulator in one click without additional external equipment or software, and perform real-time position and track generation as well as inertial navigation data conversion.
The system supports the output of 3-axis acceleration information and 3-axis orientation angle information at 1000 Hz, and can be customized to include error models for rapid validation of IMU algorithms or for testing the performance of IMU units in conjunction with hardware platforms.
Multiple RTK test methods
HONGKEI Safran GNSS simulator supports RTK simulation on top of GNSS simulation, providing vehicles with high-precision fusion positioning performance testing and evaluation capabilities. the Skydel GNSS simulator engine has an innovative MULTI feature, bringing more flexibility and possibilities for RTK testing.
Realistic Scene Restoration
HONGKE Safran GNSS simulator is dedicated to restoring the real test scene, providing users with a simulation experience and test results that are closer to the actual application. Based on the humanized and modern design concept, the system integrates satellite simulation, error injection, and motion setting into one software platform, allowing users to build and adjust the scene directly in the Skydel software.
At the same time, the system retains a high degree of customization and rapid automation capabilities, allowing users to quickly complete model setup and import, establish test cases and automation processes, and further develop standardized test methods based on existing test metrics and methods.
Facilitates open/closed loop simulation testing at all levels of the terminal to be tested.
HONGKE's GNSS simulators provide simultaneous GNSS signals and IMU signals while further simplifying the overall test system composition and implementation.
The system can be installed on the same Linux Ubuntu platform as other software, which provides stable and reliable operation and reduces maintenance effort. The simulator has a built-in high-performance time card for precise time synchronization and alignment, eliminating the need for additional atomic clocks or other synchronization devices. In addition, the system can also be quickly co-coordinated with other hardware and software, helping users to complete the construction of customized test solutions in a shorter period of time, and realizing HIL / DIL verification of the test object to be tested.
Example of program testing
On the only host computer software, Skydel, users can complete a series of scene configuration, signal generation, real-time adjustment and automation operations without relying on additional software or hardware, making the operation simple and intuitive, and providing good testing efficiency.
