ComNav GNSS OEM Boards Used in China Driving Test System

July 19, 2013  - By 0 Comments

Along with booming auto sales in China has come an increase in auto accidents, which has been a headache for the Chinese government. According to police statistics, most of the accidents in the past couple of years were being caused by new  drivers, who have been ignominiously dubbed “road killers.”

One year ago, the China Police Ministry decided to change the method of licensing new drivers by using stricter methods for training and testing. The new system also was designed to avoid cheating.

Under to the new testing system rules, the high-accuracy GNSS receiver became the ideal sensor to enforce the new testing, according to ComNav, a ShangHai-based OEM receiver maker. By offering a turnkey solution, from November 2012 to July 2013 ComNav sold more than 5,000 GNSS OEM boards/receivers for driver testing — the major share of that market.

The system uses the real-time kinematic (RTK) method to establish the accurate heading and position of the car, with a ComNav M600 GNSS receiver. A base station sends differential data to a rover installed on the car. With the help of 3G or Wi-Fi, the real-time data is transmitted to the control center. Examiners can then can judge whether the car is in the right area. Both the trainee and system will know the testing results without delay.

Surveying the testing place, marking the testing area, and measuring the car shape need to be done before the installation.

ComNav Technology Ltd. is a high-accuracy positioning solutions supplier that focuses on high-accuracy GNSS core technology R&D, manufacturing and marketing. ComNav is the first Chinese high-accuracy GNSS OEM board manufacturer and producer of a GPS+BeiDou OEM board.
