Due to the complexity of differential correction service infrastructure and high cost of GNSS receiver hardware, the GNSS RTK technology has been used just in traditional low-volume markets such as surveying and mapping, but not in many emerging high-volume markets such as autonomous vehicles, V2X and robotics. This situation will be definitely changed by technological progresses. In addition, there are currently more than 100 satellites that can be tracked and used from all four GNSS constellations (GPS, GLONASS, Galileo, and BeiDou which was just announced recently by China to provide global services). Moreover, it will not be just a dream that the 5G data will carry RTCM correction data as well in the near future, according to China Mobile, the world's largest mobile operator.
The GNSS high precision positioning market has reached a time of transition.
Bynav (Bynav Technology Co., Ltd.), a leading supplier of GNSS high precision positioning receivers in Chinese vehicle driver testing application market, officially released the C1 GNSS RTK receiver and the A1 industrial-grade IMU-enhanced GNSS receiver based on Bynav GNSS baseband ASIC Alita and RFIC Ripley.
The C1 GNSS RTK receiver board measures 46×71mm and supports dual-antenna heading and full-constellation, including GPS, BDS, Galileo, GLONASS, QZSS, NavIC and SBAS, as well as providing enhanced interfaces like UART serial port, Ethernet, 3 EVENT_IN, 3 EVENT_OUT, 1PPS, CAN bus etc. for easy integration with external IMU, odometry, LiDAR or visual SLAM.
See the rest results below:
The A1 GNSS/INS receiver, measuring 46×71mm and weighing 25g, is highly integrated with an industrial-grade IMU (gyro 2.7deg/hr) with an embedded deeply coupled GNSS+INS algorithm engine as well as tilt measurement algorithm to provide stable, high precision position and attitude even in the event of GNSS outages.

Most of the vehicle driver testing centers in China have automated their exams with the assistance of GNSS high precision positioning. As a strategic partner of Duolun Technology, China's top1 vehicle driver testing system integrator, thousands of drivers testing vehicles equipped with Bynav GNSS RTK receivers are running around China every day.

The R&D team of Bynav has been engaged in the construction of China BeiDou Satellite Navigation System since 2002. With a powerful and experienced GNSS experts’ team and large-scale scenario verification on dynamic driver testing vehicles, Bynav has successfully developed the high-precision GNSS baseband ASIC Alita and the RFIC Ripley which have been now integrated in the A1 and C1 products.
The performance of the A1 and C1 have been verified and recognized by many domestic customers in the field of vehicle driver testing and autonomous driving.
Ying Long, deputy general manager of CIDI (Changsha Intelligent Driving Institute), a well-known autonomous driving company in China, commented, “we are committed to developing intelligent driving vehicles and commercializing them as soon as possible, in which the GNSS/INS receiver plays an important role to provide absolute position. That’s why I started work together with Bynav for a cost-effective and high-performance positioning solution. Currently the Bynav’s GNSS/INS receivers have been used in our unmanned sweepers, self-driving trucks and other products, and it comes out that the A1 performance is comparable to the world-class and high-end products we used."
Besides, both receivers support dual-antenna heading and full-constellation and full-frequency tracking (including BDS-3 and L5)*, and provide SD card interface for raw data storage.
Currently both C1 and A1 are available for direct purchase. For wholesale price, please contact en@bynav.com.
