Lighthouse Technology and Consulting Co. Ltd. has developed of a series of front-end processors for GNSS software receivers. The Hibiki processors can take input from up to four frequency GNSS signals simultaneously. The Hibiki front-end can process up to four GNSS signals for software receivers. (Image: Lighthouse) The Japanese Quasi-Zenith Satellite System (QZSS) broadcasts GNSS signals in four frequency bands: L1, L2, L5 and L6. Similarly, GPS and GLONASS broadcast in three bands, and the European Galileo and Chinese BeiDou systems broadcast in four bands. However, many conventional front-ends process only two bands at the same time, and cannot be used for highly specialized applications such as processing multiple signals with different frequencies at the same time. The Hibiki front-end processor was designed to answer to this GNSS technology demand and is able to process up to four frequency bands simultaneously, the company said. Hibiki has a high data transfer rate performance using USB 3.0, stably transmitting signal data to the host computer up to 50 million samples per second. This high sampling frequency is much greater than conventional front-end processors, improving L5 signal-receiving performance and reducing multipath. Hibiki is available starting in April.
