The new front-end "the Hibiki" brings new possibilities to engineers and experts involved in GNSS with unprecedented performance.
Japan's QZSS provides GNSS signals in four frequency bands, L1, L2, L5, L6.
Also, US GPS and Russian GLONASS have 3 waves, European Galileo and BeiDou China has 4 waves. Conventionally, many front ends could process only two waves at a time, and could not respond to highly specialized applications, such as processing signals of other different frequencies simultaneously.
To meet such needs, Lighthouse has developed Hibiki, a front-end product group that can process up to four simultaneous waves. In addition, some products in the line-up can input 4 antennas and 16 antennas.
This Hibiki stably transfers signal sample data as much as 50 million times per second to the host computer using USB 3.0 high-speed data transfer. This high sampling frequency also does not exist in the conventional front end. it can be used to improve reception of L5 signal, improve development of multipath reduction function etc. as well as receiver development.
