    Inertial Labs has launched a new GNSS-aided inertial navigation system. INS-DM is an IP68-rated version of the company’s new generation of super ruggedized units, shielded from electromagnetic interference. The fully integrated device combines the inertial navigation system (INS) with an attitude and heading reference system (AHRS) and air data computer (ADC).

    The high-performance strapdown system determines position, velocity and absolute orientation (heading, pitch and roll) for any device on which it is mounted. Horizontal and vertical position, velocity and orientation are determined with high accuracy for both motionless and dynamic applications.

    The INS-DM can support multiple types of micro-electromechanical (MEMS) inertial measurement units (IMU) developed by Inertial Labs. The INS-DM also supports other IMUs like the Honeywell HG4930.

    The INS-DM uses different multi-constellation (GPS, GLONASS, Galileo, BeiDou and QZSS) GNSS receivers such as the NovAtel OEM7 series or the u-blox F9 series.

    The optional ADC is supported by two Honeywell barometric sensors and the ability to support an internal fluxgate or external stand-alone magnetic compass. The INS-DM contains Inertial Labs’ new onboard sensor-fusion filter, state-of-the-art navigation and guidance algorithms, and calibration software.

    Key Features

    • Commercially exportable GNSS-aided INS
    • 3-in-1 strapdown system: INS + AHRS + ADC
    • Embedded industrial, tactical or navigation-grade Honeywell or Inertial Labs MEMS IMU
    • Novatel OEM7 or u-blox ZED-F9P high-precision GNSS receiver
    • GPS, GLONASS, Galileo, BeiDou, QZSS and real-time kinematic signals supported
    • Total and static pressure sensors for calculating indicated airspeed
    • SBAS, DGPS, RTK and PPP corrections supported for precise real-time operation
    • GNSS measurements and IMU raw data for post processing
    • Advanced, extendable (based on application) embedded Kalman-filter-based sensor fusion algorithms
    • State-of-the-art algorithms for different dynamic motions of helicopters, UAVs, marine vessels and ground vehicles
    • Full temperature calibration of all sensing elements
    • EMC, EMI and ERD protection (MIL-STD-1275)
    • Environmentally sealed (IP68)
    • Aiding data: wind sensor, air-speed sensor, Doppler shift from locator (for long-term GPS-denied environments), external position and external heading.

    The INS-DM is the result of more than 20 years of Inertial Labs’ experience developing and supplying INS solutions to land, marine and aerial platforms around the world.

    Bynav Technology Co. Ltd. has released the C1 GNSS RTK OEM receiver and the A1 industrial-grade IMU-enhanced GNSS OEM receiver based on Bynav GNSS baseband ASIC Alita and RFIC Ripley. Bynav supplies GNSS high-precision receivers to the Chinese vehicle driver-testing market.

    The C1 GNSS RTK OEM receiver board measures 46 × 71 mm and supports dual-antenna heading and full-constellation, including GPS, BDS, Galileo, GLONASS, QZSS, NavIC and SBAS, as well as providing enhanced interfaces like UART serial port, Ethernet, 3 EVENT_IN, 3 EVENT_OUT, 1PPS and CAN bus for easy integration with an external inertial measurement unit (IMU), odometry, lidar or visual SLAM.

    The A1 GNSS/INS OEM receiver, measuring 46 × 71 mm and weighing 25 g, is integrated with an industrial-grade IMU (gyro 2.7deg/hr) with an embedded, deeply coupled GNSS+INS algorithm engine as well as tilt measurement algorithm to provide stable, high-precision position and attitude even in the event of GNSS outages.

    Most of the vehicle driver testing centers in China have automated their exams with the assistance of GNSS high-precision positioning. As a strategic partner of Duolun Technology, China’s driver-testing system integrator, thousands of drivers testing vehicles equipped with Bynav GNSS RTK receivers are moving around China every day.

    The R&D team of Bynav has taken part in the construction of China BeiDou Satellite Navigation System since 2002. With a powerful and experienced GNSS experts’ team and large-scale scenario verification on dynamic driver-testing vehicles, Bynav has successfully developed the high-precision GNSS baseband ASIC Alita and the RFIC Ripley which have been now integrated in the A1 and C1 products.

    The performance of the A1 and C1 have been verified and recognized by many domestic customers in the field of vehicle driver testing and autonomous driving.

    “We are committed to developing intelligent driving vehicles and commercializing them as soon as possible, in which the GNSS/INS receiver plays an important role to provide absolute position,” said Ying Long, deputy general manager of the Changsha Intelligent Driving Institute, a well-known autonomous driving company in China. “That’s why I started work together with Bynav for a cost-effective and high-performance positioning solution. Currently, the Bynav’s GNSS/INS receivers have been used in our unmanned sweepers, self-driving trucks and other products, and it comes out that the A1 performance is comparable to the world-class and high-end products we used.”

    Both receivers support dual-antenna heading and full-constellation and full-frequency tracking (including BDS-3 and L5), and provide SD card interface for raw data storage.

    Both C1 and A1 are now available for direct purchase. For wholesale price, contact [email protected].
