Alpi and Kuro Electric co., Ltd. jointly produced the UMSZ6 series GNSS1 module, which can achieve high-precision positioning within 50cm without data correction, claiming to be the world's first vehicle-mounted application. Even on general roads (about 3m wide), the module reliably facilitates vehicle positioning to lane level, which is required by various V2X2 applications, thus adding a higher level of complexity to autonomous driving functions.
GNSS module uses the multi-frequency GNSS receiver chip based on guye extended carrier assist technology to achieve its high-precision positioning. Eliminating the operational costs associated with RTK4 base stations, calibration data reception and calibration data usage maximizes cost performance while reliably positioning to lane level even on general roads. The company's module creation expertise accumulated over many years in the automotive business was applied to achieve a compact size of 17.8mm x 18m x 3.11mm, while adhering to the automotive class and contributing to the customer's freedom in the final product design.
In joint development, Furuno developed and provided an original multi-frequency GNSS receiver chip eRideOPUS 9(Model ePV9000B) and algorithm. Alpine pioneered the use of these chips in the production and commercialization of the UMSZ6 series GNSS modules.
"Due to the development of millimeter wave radar, lidar and camera technology, the relative positioning accuracy of vehicles continues to improve," said Hideo Izumi, vice president of Alps equipment Business. Achieving absolute position accuracy at the lane level is critical for V2X applications and true Level 3 autonomous driving, but the system-related costs associated with RTK technology have been an obstacle. Addressing this problem with Furuno's Extended Carrier Technology to achieve vehicle positioning accuracy within 50 cm promises to be a breakthrough in V2X and advanced autonomous driving."
Motokawa Katsuori, Furuno Electric Co. Ltd system Products general manager said："Through its partnership with Alps Alpine, which has extensive experience in the automotive market, module creation expertise that meets stringent automotive class standards, and c-V2X systems, autonomous driving is making rapid progress in the automotive industry with increasing demands for positioning accuracy. "We believe the high positioning accuracy achieved by Furuno will contribute to practical applications and increase the complexity of autonomous driving technology."
