GNSS receiver
With embedded 9-DOF IMU
Photo: Rokubun
The Argonaut GNSS receiver is able to provide geo-location with real-time accuracy of 2 meters and off-line accuracy better than 0.4 meters using Argonaut PaaS. This is possible because GNSS raw measurements, together with inertial measurement unit (IMU) nine-degrees-of-freedom (9-DOF) measurements, are stored for offline GNSS processing (PPK, RTK, DGNSS). Argonaut will also register external events such as camera triggers within microsecond resolution and decimetric geo-location accuracy. The embedded IMU allows for an increased rate of navigation fixes as well as robust solutions in scenarios with impaired GNSS availability.

Portable simulation
Solution for field-test requirements
Photo: CAST Navigation
The CAST-1000 duplicates GPS RF signals and uses dual-frequency signal generation technology. This allows for duplicate testing in the laboratory or the field and real-time or configured control. The CAST-1000 is mobile and portable, which makes it the ideal solution for field test requirements. Producing GPS and GLONASS signals with up to 12 satellites in view, the CAST-1000 simulates signals for satellites of P code on L1 and L2 and C/A code on L1. The GPS RF signal is dual-frequency and has a 12-channel configuration for any combination of visible space vehicles. The system is highly programmable — operators can choose from an array of vehicle types and replicate dynamic motion for all kinds of vehicles, from terrestrial to aquatic, airborne to space-based. By utilizing 6-DOF dynamic profile data collected in the field and through profile configuration, a trajectory can be created. The CAST-1000 also features a performance evaluation module, allowing for comparisons between raw and filtered data.

Indoor mapping
Slam technology removes point cloud artifacts
Photo: NavVis
The SLAM-based NavVis M6 Indoor Mobile Mapping System (IMMS) now automatically detects and removes point cloud artifacts, including moving objects in static scenes. The latest IMMS release removes artifacts from point clouds during the post-processing of scan data (see before and after image above). Fringe points and dynamic objects are two common types of point cloud artifacts that affect all 3D laser scanning devices. The NavVis M6 IMMS uses laser scanners to capture a high volume of measurement points of an environment. With the latest software update, the algorithms applied during the post-processing of scan data uses the multiple observations to detect whether measurement points actually exist in the physical space. If it is determined that the point does not exist and is instead resulting from the laser beam hitting an edge or an object moving through the space, this point is automatically removed. The result is a much cleaner, crisper point cloud that requires less clean-up time in point-cloud editing software and that is easier to use for applications such as BIM modeling.

RTK Hexacopter
Integrated GNSS improves accuracy
Photo: Yuneec International
The H520 hexacopter is now available with a real-time kinematic (RTK) system. The fully integrated RTK satellite navigation enables extremely accurate recurring images and faster 3D mapping. It also makes automated inspection flights easier and more precise. The H520 RTK is suitable for commercial applications that require maximum precision. By using RTK technology, the H520 can now fly much closer to objects for inspection because the UAV positions itself precisely in the centimeter range (1 cm + ppm horizontal / 1.5 cm + ppm vertical) rather than in the meter range, which is standard for the H520.
