FURUNO ELECTRIC CO., LTD. is pleased to announce that new multi-GNSS receiver chips eRideOPUS 6 and eRideOPUS 7 will be available to the market from August 2013 onward. The new receiver chips are multi-GNSS compliant single-chip LSIs, capable of concurrently receiving signals from multiple satellites of GNSS systems, i.e., GPS, GLONASS*, Galileo, etc., and Satellite-Based Augmentation Systems (SBAS) as well as Japan's Quasi-Zenith Satellite System (QZSS).
* eRideOPUS 7 only
The ability to concurrently receive GNSS and GNSS augmentation signals from multiple satellites belonging to different satellite services means that the receivers have a higher probability of acquiring a greater number of satellites at any single point in time. Subsequently, position stability as well as position accuracy will be greatly improved, minimising the chance of a position loss. In addition, the receiver chips incorporate an enhanced level of noise rejection capability, through the implementation of an Active Anti-Jamming and an Advanced Multipath Mitigation functions.
Time-To-First-Fix (TTFF) capability of the existing eRideOPUS 5 GPS receiver (less than 1 second when hot started) is also achieved by these new receiver chips with a combination of A-GNSS (network assisted) compatibility and Self-Ephemeris™ prediction. Moreover, the position update rate of the new receiver chips is greatly improved, achieving up to 10 Hz update rate (every 0.1 second), which is twice as fast as the capability achieved by eRideOPUS 5.
The new receiver chips are capable of dead reckoning navigation, using a gyro sensor and vehicle speed pulse signals, or a gyro sensor and an acceleration sensor, or wheel tick data taken from a CAN-Bus network, or a fusion of all these sensor data, achieving high positioning accuracy even in locations where satellite signal reception is not available, such as inside tunnels and under-ground parking.
In May 2013, FURUNO will start supplying evaluation kits for the new receiver chips to allow third-party manufacturers to evaluate the benefits of incorporating these receiver chips into their products. In August 2013, the new compact GNSS receiver modules GN-86F & GN-87F as well as the dead-reckoning-capable GNSS receiver modules GV-86 & GV-87, build around these new receiver chips, will be available for integration into automotive navigation systems as well as Telematics and eCall systems.
