Integrated GNSS receiver helps speed workflows
The VZ-600i terrestrial laser scanner has a 3D position accuracy of 3 mm and less than 30 seconds of scan time for high-resolution scans with 6 mm point spacing at 10 m. This enables more than 60 scan positions per hour with real-time registration. Weighing less than 6 kg (13 pounds), the VZ-600i has a 2.2-MHZ pulse repetition rate, three internal cameras and an integrated GNSS receiver. It also includes key features to speed up workflows in indoor and outdoor applications such as architecture, engineering, construction, building information modeling, as-built surveying, forensic and crash scene investigation, archaeology and cultural heritage documentation and forestry.
For UAV lidar and photogrammetry
The LP360 Drone software system provides a geospatial-data workflow for UAV lidar and photogrammetry data processing. It provides powerful point cloud visualizations with multiple, synchronized windows. It can transform lidar and imagery data into survey-grade deliverables including visualization, quality checks, classification, analysis and 3D editing. For users of larger datasets, LP360 Geospatial can process captured lidar data or images from any aircraft or mobile sensor and analyze and extract values.
Free library offers data on healthcare, business, traffic
The extensive Maptitude library of free mapping databases has been updated for 2022 and is available for download, supporting insightful business development analysis. The data is available free to users of the latest version of the Maptitude mapping software. The data are also available as shapefile, KML, KMZ or GeoJSON for a fee. Maptitude includes business-critical data such as demographics, boundaries, streets, and the most ZIP Code/postal boundaries. Also available is a catalog of free premium datasets that can be used in other GIS applications, on the web, or in corporate databases.

Asset Tracking Solution
Indoor and outdoor tracking of low-power, small IoT devices
Traxmate is integrating Nestwave GNSS location technology into its asset-tracking platform for seamless indoor and outdoor positioning, tracking and routing of small, low-power and battery-powered devices for the internet of things (IoT). Nestwave’s NestCore IP and NestCloud cloud services enable power-efficient geolocation solutions, while Traxmate (pictured) is a comprehensive data-processing hub that simplifies setup of tracking environments and provides real-time visualization of device location. The resulting geolocation solution is suitable for applications ranging from carrier tracking to tracking individual parcels and packets. Traxmate is simple to use and set up, requires no coding, and provides an out-of-the-box feature set that includes dashboards, alerts and processing rules for taking actions on incoming data. Nestwave’s trackers include ThinTrack, an ultra-low-profile, compact GPS tracking solution that integrates an LTE-M/NB-IoT modem, antenna, battery and SIM into a device that measures 82 mm x 35 mm x 3 mm and weighs 15 g.

Provides guidance even without an internet connection
The Sygic GPS Navigation app uses a smartphone’s camera and augmented reality to display navigation instructions over the view ahead on the windshield. The head-up display is especially useful at night, enabling recognition of critical speed limit, road work or traffic restriction signs. Cockpit is a powerful tool that shows the real-time performance of the car, measuring the G force and actual speed to help users drive economically. The Dashcam feature records the road ahead and automatically saves the video in case of an accident. An Electric Vehicle Mode locates nearby charging stations.

Enhanced data-based rule implementation for fleets
An enhanced SureCam video telematics integration provides fleet managers with access to new capabilities to keep drivers safe and maximize fleet efficiency. The solution features a method for capturing video footage from SureCam cameras using Geotab’s powerful telematics device and rule-based system. The result is a seamless display of video within the MyGeotab platform. The enhanced SureCam fleet video solution leverages Geotab’s numerous data-based rules, such as improper seat belt usage and speeding. It uses G-force triggered alerts that detect unsafe driving behaviors and automatically captures video footage that can be reviewed later on the MyGeotab platform and alert managers to incidents when necessary. Camera configuration and customized triggers are managed directly within MyGeotab.

Autonomous Driving Solution
Can navigate heavy traffic safely and efficiently
Driver 2.0 is a Level 4 production-ready autonomous driving solution that can operate in complex and challenging traffic environments. Demonstrations with Driver 2.0 showed an autonomous vehicle could maneuver around double-parked cars, e-scooters and pedestrians, negotiate oncoming vehicles to calculate the right timing and trajectory to pass busy intersections, and make multiple lane changes and unprotected left turns. In the case of long tail scenarios, the system will alert the remote monitoring center to intervene or take other safety measures. Driver 2.0 includes five solid-state lidar units, eight cameras and other sensors, and a computing platform integrated with a proprietary inference engine. The perception algorithm with sensor fusion can achieve precise object detection up to nearly 220 yards. The planning and control algorithm based on game theory can choose optimal routes and make decisions based on real-time situations when negotiating with oncoming vehicles and other road agents.
Provide improved signal gain for automotive antennas
Two new compounds could improve signal-gain performance compared to ceramics in second-generation automotive GNSS antennas. The new compounds — LNP Thermocomp ZKC0CXXD and LNP Thermocomp ZKC0DXXD — help enable the design and molding of antenna substrates with more complex pattern markings that add effective surface area, a critical factor in enhancing signal capture. They also provide flexibility to produce smaller parts with the same performance as ceramic, or equal-size parts with better performance. The LNP Thermocomp compounds feature electroplating capability, good thermal resistance for reliability, and the design freedom and production efficiency of thermoplastics. Both are well-suited for shark-fin-style and new conformal antenna designs.
