Dual-band GNSS Receive Chip eRideOPUS 9 Model ePV9000B NEW

Features

• 50cm DRMS position accuracy allows for lane-level navigation

  In V2X applications, it is required to determine in which lane the vehicle is driving. In autonomous driving (Level 2 to Level 3) systems, the absolute position information can be used as a reference to accomplish localization through cameras, LiDAR devices, and HD maps. eRideOPUS 9 allows reliable lane positioning, including on narrower lanes (approximately 3m wide).

• Extended Carrier Aiding Technology

  eRideOPUS9 integrates Furuno's proprietary Extended Carrier Aiding technology. It is a stand-alone on-chip function which does not have any running costs unlike the RTK and PPP technologies, which rely on extended networks of reference stations and the reception of correction data.
  With its excellent cost performance, eRideOPUS 9 will greatly contribute to the develpment of V2X and autonomous driving (Level 2 to Level 3) systems.

• Dead Reckoning

  High-precision location information is generated by connecting a 6-axis inertial sensor and feeding in vehicle speed pulses.

• Dual-band, Multi GNSS

  eRideOPUS 9 supports all navigation satellite systems currently in operation from U.S. (GPS), Russia (GLONASS), Europe (Galileo), China (BeiDou), Japan (QZSS), and India (NavIC), as well as augmentation systems (SBAS).
  In addition to L1 signals, it receives L5 signals as well.
  The L5 signals improve positioning accuracy in environments where radio waves are reflected or diffracted by structures, like in urban areas.
  In addition, the L5 signals have a wider frequency bandwidth, an improved signal structure, and are transmitted at a higher power than L1 signals, which make them more resilient and allow for a more stable reception in harsh environments.

• Anti-Jamming, Anti-Spoofing

  To be used for applications that require stable positioning information, eRideOPUS9 includes enhanced durability against jamming and spoofing.
  It is also equipped with a function to detect such attacks and report them to the ECU.

• Time pulse output (1PPS)

  eRideOPUS 9 provides a time pulse output to allow a highly accurate synchronization between different devices and systems in an application.
  It provides highly accurate 1PPS synchronized with GPS time even at high-speed driving.

• RAW DATA output

  eRideOPUS 9 outputs GNSS and the 6-axis inertial sensor RAW data for users who want to use their original or third-party positioning engines.

• With eMRAM, no flash memory required

  eRideOPUS 9 has eMRAM embedded on the chip, which contains the firmware and allows for firmware upgrades. There is no need for an external flash memory.
