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.

ViaLite adds resilience to critical GPS timing services

Diagram: ViaLite

Diagram: ViaLite

ViaLite’s RF-over-fiber systems can carry GPS/GNSS timing signals over long distances with very low signal degradation. However, the same cannot be said of GPS signals before they reach the GPS/GNSS antenna, as these weak radio waves are highly susceptible to jamming or spoofing.

Timing-critical infrastructures in areas such as defense and cyber security can now be protected from this kind of attack by installing one of ViaLite’s new GPS Protection Packages. The packages integrate either the GPS Resilient Kit or OtoSphere Protection Module products from Focus Telecom for jamming protection.

The GPS Resilient Kit has two GPS antennas, which enables the direction of the attack to be pinpointed. At its heart is the small OtoSphere Protection Module, which has a unique interference filtering algorithm that combines the patterns from the two omnidirectional antennas.

The module can analyze the direction from which the interference is coming and feed it into its algorithm, directing a null towards the unwanted signal to reject and reduce disruptions.

Using OtoSphere, GPS receivers are up to 50 times more resilient to jamming attacks on positioning, navigation and timing (PNT) systems compared with having no protection. The GPS receiver is able to continue working normally throughout the attack.

“ViaLite customers typically need the highest grade of reliability and service, particularly for critical infrastructure timing applications,” said Richard Jacklin, ViaLite sales director. “With the increase in jamming threats, both land-based and maritime, these Focus Telecom anti-jamming products are a perfect complement to our range of GPS/GNSS signal distribution solutions.”

The Protection Packages can be integrated into new installations or retrofitted to existing ViaLite systems. The GPS Resilient Kit and OtoSphere are already IP-rated, so they can be simply added to outdoor installations. Alternatively, for a full package solution, the OtoSphere module can be integrated into the ViaLite ODE-MINI outdoor enclosure.

The packages are suitable for use in critical infrastructure sectors such as defense, satcoms, utilities, cellular communications, broadcast, data centers and transportation.

Other Focus Telecom products, introduced by ViaLite, include the GPSensor for monitoring GPS frequencies and reporting intentional and unintentional attacks, and the GPS RF Switch which protects PNT systems from vulnerabilities by isolating them from the RF signals coming from the antenna.

SBG Systems introduces its first tactical-grade IMU

SBG Systems is introducing the Pulse-40 inertial measurement unit (IMU), a tactical-grade IMU designed for high performance in harsh conditions, but miniaturized for applications where precision and robustness matter in all conditions.

Use cases include warfare systems, satellite communications, robotics, lidar devices, gimbals, cameras and inertial navigation systems (INS).

The Pulse-40 IMU provides six-degrees-of-freedom. It integrates micro-electromechanical (MEMS) three-axes accelerometers and gyroscopes in a unique redundant design that allows the device size to shrink while pushing performance to its maximum.

Among the performance specifications, the Pulse-40 features excellent gyro and accelerometer bias instability of 0.8°/h and 6 µg respectively, enabling long dead-reckoning and maintaining excellent heading performance. With sensors featuring extremely low vibration rectification error (VRE), the Pulse-40 is able to sustain high vibration environments, up to 10 g root-mean-squared.

An embedded continuous built-in-test ensures data reliability during operation, a key parameter for critical applications. The Pulse-40 requires no periodic maintenance. An intensive qualification process — including accelerated aging — guarantees that the sensor behavior is stable over time.

Main Features

  • Size, weight and power (SWaP) design: 12 grams, 0.3W Power consumption
  • Ultra-low noise gyro (0.08°/√h) and excellent gyro bias instability (0.8°/h)
  • High-precision accelerometers (6 µg)
  • Low vibration rectification error: shocks and vibrations MIL-STD 810 qualified
  • High bandwidth (480Hz) and high data rate (2KHz)
  • Highly tested and calibrated from –40° C to 85° C
  • No export restrictions

Research Result

SBG Systems’ sensor calibration and validation tools, initially based on a single axis motion simulator with a temperature chamber, have evolved over the years and are now based on 100% automated, multi-axis motion simulators with temperature chambers. The high level of automation mitigates human-error risk and ensures that all the delivered products meet their specifications. Its  INS are the result of extensive research in signal processing, micro-electronics, calibration algorithms and sensor qualification, the company said.

With very low gyro noise and bias instability, the navigation performance is maximized in GNSS-disturbed or -denied environments. The Pulse-40 is export license free and ITAR free.

Because of its small size and low weight, the xNAV650 is suitable for SWaP-constrained applications. It is also used in many mobile-mapping scenarios. Alongside OxTS Georeferencer, measurements created by the xNAV650 can be used to georeference point clouds from multiple lidar sensors.

By announcing these new specifications, OxTS aims to keep surveyors informed of the performance they can expect from the xNAV650 in both real time and post-processing.

OxTS has been manufacturing INS for more than 20 years. Their INS are widely used in both the automotive testing and survey and mapping industries.

Reports from the winning grant proposals 2021

With the QGIS Grant Programme 2021, we were able to support eight proposals that are aimed to improve the QGIS project, including software, infrastructure, and documentation. The following reports summarize the work performed in the proposals. 

  1.  QGIS Server and services documentation (#213) – Report
    The Services chapter of the QGIS Server documentation needed some love to
    be effectively representative of the underlying implementation. Numerous
    services, requests or parameters were not documented at all. Some others
    also had very sketchy descriptions. Thanks to this QEP, the Services
    chapter is now in a much better shape!
  2. Rework handling of multi-layer, mixed-format datasets (#216) – Report
    While the work was partly motivated as an opportunity to clean up some
    older parts of the QGIS codebase which were fragile and had low test
    coverage, it has also resulted in many improvements and polish in the
    QGIS user interface.
  3. Port DB Manager Table Management Functionalities to Browser: SQL execution (part 3) (#205) – Report
    Besides SQL execution functionalities, an additional PR adds to QGIS core the query layer management tool that was provided by DB Manager plugin. The new API is fully covered by unit tests.
  4. Locale support for numeric input and display: revision and enhancements (#210) – Report
    The work has been completed with multiple pull requests that fixed all localization issues that have been reported plus countless unreported issues that have been identified along the way.
  5. Integrate GPS Tools plugin functionality into core QGIS (#217) – Report
    This grant sees the removal of the old, unmaintained “GPS Tools” core plugin, with all functionality from the plugin moved to reusable Processing algorithms or the unified Data Source Manager dialog. Since the functionality now uses the Processing framework, users gain the ability to run these tools in batch modes, as part of graphical models, and from 3rd party scripts and plugins. As a bonus the new tools are all fully covered by unit tests.
  6. QGIS Server, OGC tests and Continuous Integration: OGC API Features (part 2 (#212) – Report
    Thanks to the QEP funding, the OGC API Features standard for QGIS Server is
    now checked in QGIS continuous integration since end-November 2021.
  7. Fixing terrain and camera issues in 3D (#215) – Report
    These improvements should make the 3D map view easier to use. Especially the camera control issues (unintuitivie camera rotation and wrong center point) were quite tricky to fix.
  8. Review process on plugins.qgis.org and improvements (#219) – This proposal has been withdrawn.

Thank you to everyone who participated and made this round of grants a great success and thank you to all our sponsor and donors who make this initiative possible!
