ComNav GNSS OEM Boards Used in China Driving Test System
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.

ComNav BeiDou+GPS Receiver Provides Positioning in Antarctic
China’s icebreaker Xuelong, or Snow Dragon, returned to Shanghai April 9 after successfully completing China’s 29th Antarctica scientific expedition. As a high-accuracy GNSS solutions provider, ComNav supplied a GPS+BeiDou GNSS receiver for this expedition. This was the first time that the ComNav GNSS receiver worked in such an extreme environment.
The reliable performance of the receiver impressed the expedition team. “The fast-searching satellites speed and the accurate positioning result saved us lots of time in the extreme cold field,” said one team member. It was the first time that a BeiDou receiver was used in the Antarctic, according to ComNav.
The research vessel left the southern port city of Guangzhou on November 5, 2012, for Antarctica. It covered 29,000 nautical miles over its 156-day southern voyage, among which 6,000 nautical miles were in ice regions. A total of 239 researchers on board completed 53 research tasks on biology, ecology, geophysics, ocean, climate, environment and glacier, and engineering construction missions.
