Achieves centimeter-level positioning
Able to simultaneously receive positioning signals from multiple satellites, enabling centimeter-level high-precision positioning.
Conventional GNSS signals (L1) have an error of about 2~50 m due to the way they work when just receiving radio signals. To obtain highly accurate position information, multiple signals from satellites must be received, generally GNSS L1/L2 signals plus network RTK and L6 (MICHIBIKI) augmentation data to achieve centimeter-level accuracy. MinebeaMitsumi has succeeded in miniaturizing an antenna that receives these multiple signals (L1/L2 or L1/L2/L6).
Customization is possible according to each customer's request.
Applications : Car navigation, ecall, Autonomous driving
Various Applications
Design technology and synergistic power that supports antennas
Unique stack structure antenna design
In-house Antenna pattern design and production
Pattern printing accuracy 30μm or less
Interference design that enables combination
What is high precision GNSS?
Antenna covering L1 band to L2, L5/L6 in each country. Achieves error range accuracy of 10cm or less by receiving complementary information in addition to location information.
Current in-vehicle GNSS antennas are mainly antennas that cover the L1 band of each country.
Accuracy is low due to positioning conditions and surrounding environment
(radio wave reflection, etc.)
・GPS,GNSS error is about 2~50 m (Status of not receiving supplementary information)
The accuracy of the navigation is complemented by not only GNSS, but also map information,
3-axis gyro information, and position information from the network.
