GNSS-modul opererer med præcision på 50 centimeter

Alps Alpine og Furuno har udviklet GNSS-modul, der gør det muligt at stedplacere et køretøj med en præcision inden for 50cm uden brug af korrektionsdata (in english).

Even on general roads (approx. three meters wide), the module reliably enables vehicle positioning down to the lane level, as is required of various V2X2 applications, thereby contributing to greater sophistication of autonomous driving functions.

With a view to undertaking sales promotion activities worldwide, efforts will be made to enhance the degree of completion of the product through performance evaluations involving demonstration testing. We aim for a start to mass production in 2023.

Technological innovation is gathering momentum within the automotive CASE domains (Connected, Autonomous, Shared & Services, Electric). In the autonomous driving domain, a growing number of vehicles on the road have Level 2 automated driving capability, allowing them to autonomously follow the vehicle in front under certain conditions while staying in their lane.

Cars capable of Level 3 automated driving, where the system carries out all driving tasks but under restricted conditions, such as during expressway or low-speed driving, have also recently been developed. Some are already on the market. However, the spread of Level 3 autonomous vehicles and further advancements in autonomous driving functionality will depend on the availability of vehicle positioning that is more user-friendly and even more accurate.

The UMSZ6 Series GNSS Module jointly developed by Alps Alpine and Furuno realizes high-accuracy vehicle positioning to within 50 centimeters even without having to use position correction data, a world-first for automotive applications. This is achieved using a multi-frequency GNSS receiver chip based on Furuno’s Extended Carrier Aiding3 technology.

Running costs associated with RTK4 base stations, correction data receiving, and correction data use are no longer needed, maximizing cost performance, while reliable vehicle positioning down to the lane level is possible even on general roads (approx. three meters wide).

Alps Alpine expertise in module creation accumulated over many years in the automotive business was applied to realize compact dimensions of 17.8 × 18.0 × 3.11mm while conforming to automotive grade, contributing to greater freedom for customers in end-product design.

Under the joint development, Furuno has developed and supplies an original multi-frequency GNSS receiver chip – eRideOPUS 9 (model ePV9000B) – and algorithm. Alps Alpine is using the chip before anyone else to create and commercialize the UMSZ6 Series GNSS Module and will carry out evaluations within a real-car environment to assess performance and interoperability with V2X and other communication modules, and pursue sales promotion within the automotive market.

The next task will be to evaluate the module’s performance, for example through demonstration testing, and bring the product to a higher degree of completion as we look ahead to sales promotion worldwide. The aim is to begin mass production during 2023.
