    Applanix, a Trimble Company, has announced the Trimble AP+ Land GNSS-inertial OEM platform for accurate and robust position and orientation for georeferencing sensors and positioning vehicles in land mobile-mapping applications.

    The platform enables users to accurately and efficiently track and monitor fleets and produce high-definition (HD) maps and 3D models. It can also serve as a reference solution for advanced driver-assistance systems (ADAS) testing, even in challenging GNSS environments.

    The comprehensive Trimble AP+ Land is small enough to integrate into compact mobile-mapping systems. It is compatible with virtually any type of mapping sensor, including single- or multi-lidar systems, video cameras, photogrammetric and panoramic cameras, and similar sensors.

    Configurable to meet the mapping, positioning and direct georeferencing (DG) accuracy demands of mapping and positioning applications in challenging GNSS signal environments, the Trimble AP+ Land solution features:

    • Applanix IN-Fusion+ GNSS-aided inertial firmware with Trimble ProPoint GNSS positioning technology
    • Dual embedded survey-grade GNSS chipsets that can receive multi-frequency and multi-constellation signals
    • Dual custom-designed inertial measurement units (IMU)
    • Distance measurement indicator (DMI)
    • Compact size
    • Low power consumption
    • Optional RTK and Trimble CenterPoint RTX real-time correction service support
    • Full integration and post sales support through the Applanix Global support network

    “We have taken the most advanced features of Applanix inertial and Trimble GNSS technology, and packaged them into a powerful compact and versatile solution optimized for mobile mapping and positioning applications,” said Joe Hutton, Applanix’s director of inertial technology, air and land products. “We remain committed to our customers’ success by developing flexible and scalable positioning solutions such as the AP+ Land and more.”

    The Trimble AP+ Land OEM solution is supported by the Applanix POSPac MMS post-processing software, which features Trimble CenterPoint RTX post-processing for centimeter-level positioning globally without the need for base stations. These capabilities make it a suitable for integrators to produce a highly efficient land mobile-mapping system.

    For lidar integrators, the Trimble AP+ Land OEM is compatible with the POSPac MMS LiDAR QC tools. SLAM technology computes the IMU to lidar boresight misalignment angles and also adjusts the trajectory to achieve the highest level of georeferencing accuracy in the generated point cloud.

  • NovAtel’s OEM7 7.03.00 firmware offers new and enhanced features

    NovAtel’s OEM7 7.03.00 firmware offers new and enhanced features

    NovAtel’s OEM7 v7.03.00 firmware is now available on all OEM7 receivers. The OEM7700, OEM719 and OEM729 can be updated to the 7.03.00 firmware, which supports new features like the SPAN Land Vehicle technology, direct inertial measurement unit (IMU) connections and tracking of the NavIC Indian regional satellite system on the L5 frequency.

    The SPAN Land Vehicle feature provides performance benefits specifically for extended loss of GPS signals, robust alignment routines and improved attitude performance for fixed-wheel land vehicle applications. During extended periods of GNSS outage, typically in low-dynamic operating environments or in dense urban canyons, the SPAN Land Vehicle feature optimizes integrated GNSS+INS performance to maintain accurate position, velocity and attitude.

    To achieve this, NovAtel uses intelligent vehicle dynamics modeling and its patented Antenna Phase Windup Technology. Intelligent vehicle modeling identifies IMU errors in the integrated GNSS+INS system that accumulate after extended GNSS outages and reduces the impact of those errors within the SPAN solution.

    NovAtel’s Antenna Phase Windup technology is used to sense changes in direction and, when combined with intelligent vehicle modeling, corrects for IMU errors in attitude (roll, pitch, yaw).
    Users can now connect SPAN enabled OEM7 receivers directly to the ADIS-16488 and Epson G320N IMUs using an SPI interface, and to the STIM300 IMU using RS422, without the need for an interface card.

    OEM7 receivers with NavIC L5 frequency tracking enabled will be able to access the test signals of the Indian Regional Navigation Satellite System (IRNSS) before it becomes operational (targeted for early 2018).
