  • SBG Systems drives GNSS+inertial in Paris

    SBG Systems drives GNSS+inertial in Paris

    Photo: SBG SystemsAutonomous vehicles require lane-level accuracy at all times and in all conditions. However, under many conditions, such as in urban canyons and tunnels, they may lose line-of-sight to enough GNSS satellites to achieve accurate and robust positioning or may have no signal at all. In these situations, they need data from other sensors, including an odometer and an inertial measurement unit (IMU). Creating reliable and safe autonomous navigation requires fusing GNSS and inertial technology in a multi-layered system.

    SBG Systems and its partners LeoDrive.ai and Intempora, have been doing this to develop solutions for autonomous vehicles. SBG’s technology enables multi-sensor integration while addressing such autonomous navigation challenges as time synchronization, integrity, precise positioning and high-definition mapping.

    “To ensure performance and build trust, we assemble our own IMUs from carefully selected industrial-grade parts, then we calibrate all our products individually,” said Laurent Le Thuant, business manager for SBG, in a recent webinar.

    For safe operation, Le Thuant explained, the vehicle’s true positional error (PE) must be smaller than its protection level (PL), which in turn must be smaller than its alert limit (AL): PE < PL < AL. Otherwise, the solution is declared unavailable or reports misleading information.

    In automotive tests conducted in a business district near Paris, an SBG vehicle was equipped with both a GNSS-only, automotive-grade multiband RTK receiver equipped with a PL determination algorithm and an RTK GNSS receiver tightly-coupled with an IMU and an odometry input. A comparison showed that the former was not suited for self-driving, while the latter significantly improved the solution availability, accuracy and protection levels.

    For self-driving in the most severe conditions, even this solution requires integration of supplementary sensors, such as cameras, lidars and radars for precise localization.

    More mass-market devices and vehicles are being equipped with dual-frequency GNSS receivers. With the HD GNSS service, the receivers enable high-precision positioning, HERE said, a capability that was cost and geographically prohibitive less than two years ago.

    HERE HD GNSS accelerates chipset, hardware and software makers’ ability to offer a step change in what can be delivered to consumers in new product capabilities, features and user experiences, the company said.

    HERE HD GNSS data delivery is optimized for mobile devices, requires no additional hardware and comes equipped with spoofing detection and phone sensor integration. It provides global coverage (including China and Japan), with single-frequency mobile device support in the future.

    HERE is also working across a partner ecosystem — including reference station operators, chipset manufacturers, module makers, hardware vendors, mobile network operators and system integrators — to jointly improve the positioning accuracy to centimeter levels, and in more challenging environments such as urban canyons.


    Automotive use cases

    Autonomous driving. For safety, it’s critical that automated vehicles are designed with high levels of redundancy in positioning systems. If an automated vehicle gets caught in bad weather conditions which are degrading optical sensor operations, <0.2m positioning accuracy available via HD GNSS increases safety and operation time in autonomous mode.

    Assisted driving. In case of an obstacle on the road, HD GNSS combined with HERE HD maps provide obstacle indication and avoidance functionality.

    Mobile device use cases

    Road lane guidance and improved ETAs on mobile devices. If a driver is unfamiliar with the roadway, HERE HD GNSS, combined with precision HERE map data, shows the driver the correct lane and path to navigate to the destination fast and safely.

    Improved gaming and augmented reality experience. Location-based games are growing and widely popular, however they currently rely on less accurate positioning technologies that inhibit next generation use cases. HERE HD GNSS bring exciting opportunities to design the next version of games with sub-meter positional accuracy.
