GNSS/INS Positioning Engine Integration on Renesas R-Car Automotive Computing Platform by NovAtel

Automotive-grade, Safe, Precise GNSS/INS Positioning Solutions for Autonomous Vehicle Localization

NovAtel® designs, manufactures, and sells high-precision Global Navigation
Satellite Systems (GNSS) components and subsystems for a wide range of driverless positioning applications based on proven technology that delivers sub-decimeter-level accuracy. We have integrated our precise GNSS/INS positioning engine on the Renesas R-Car automotive computing platform. This integration allows automotive designers and manufacturers maximum performance with maximum flexibility to utilize different hardware components, including GNSS chipset and automotive-grade Inertial Measurement Unit (IMU) along with the other automotive-grade sensors required for their vehicle feature function and solution. NovAtel’s positioning technology not only delivers solutions based on signals from satellite constellations, but also uses vehicle behavior modeling, inertial sensor integration, and GNSS correction signals to improve accuracy and greatly reduce interruptions in availability. The R-Car automotive computing platform that NovAtel selected is compliant with the ISO 26262 functional safety standard for automotive applications. NovAtel is an ISO 9001 certified company and offers an extensive product line of receivers, antennas, correction signals, positioning algorithms, sensor fusion solutions, and systems that fulfill specific safety requirements of the automotive industry such as ISO 26262.
