[Satellite TODAY 03-28-13] FURUNO ELECTRIC has announced the launch date for its new multi-GNSS receiver chips eRideOPUS 6 and eRideOPUS 7. The receiver chips will be available to the market from August 2013 onward.

    The eRideOPUS 6 and eRideOPUS 7 are multi-GNSS compliant single-chip LSIs, capable of concurrently receiving signals from multiple satellites in GNSS systems, such as GPS, GLONASS, and Galileo, and satellite-based augmentation systems as well as Japan’s Quasi-Zenith Satellite System.

    The ability of concurrently receiving GNSS/GNSS augmentation signals from multiple satellites from different satellite services means the receivers have more probability of acquiring a greater number of satellites at any single point of time. Position stability as well as accuracy will be improved, minimizing the chance of a position lost. Also, the receiver chips incorporate an enhanced level of noise rejection capability, implementing the anti-jamming function as well as the improvement of multi-path mitigation.

    Moreover, the position update rate of the new receiver chips can achieve a 10 Hz update every 0.1 second, which is twice as fast as the capability achieved by eRideOPUS 5, their predecessor. The new receiver chips are capable of dead reckoning navigation, using a gyro sensor and vehicle speed pulse signals, a gyro sensor and an acceleration sensor, and wheel tick data taken from a CAN-Bus network, achieving high positioning accuracy even in locations where satellite signal reception is not available, such as inside tunnels.
