SBG Systems Releases Virtual Base Station Feature in Qinertia

SBG Systems is introducing the Virtual Base Station feature in its in-house post-processing software called Qinertia. Geospatial professionals benefit from an optimal centimetric position accuracy in all their projects, even for corridor mapping and in poorly covered RTK areas. Qinertia is SBG Systems’ in-house GNSS and INS post-processing software. It gives access to offline RTK corrections from more than 7,000 base stations located in 164 countries. Trajectory and orientation are then greatly improved by processing inertial data and raw GNSS observables in forward and backward directions. Corridor survey accuracy Qinertia PPK software now includes a brand new Virtual Base Stations... (read more)

At the Forefront of the Digital Transition

GIM International talks to Thomas Harring, president of Hexagon Geosystems and CEO of Leica Geosystems
Thomas Harring started in his position as president of Hexagon Geosystems and CEO of Leica Geosystems in early 2020. The year took a sudden and very unexpected turn when the outbreak of the COVID-19 pandemic threw a spanner in the works. However, Harring emphasizes that the geospatial industry should use the momentum of the ‘new normal’ to further accelerate the sector’s ongoing transformation towards more customer-centric and autonomous digital solutions. How would you summarize the current state of the geospatial industry? Despite the undeniably terrible consequences of the current pandemic, the geospatial industry has not lost any of its importance... (read more)

PolyExplore Unveils High-Precision UAV Lidar Mapping System

PolyExplore has launched the Polyscanner LS1, a high-precision Lidar mapping system designed for UAVs and other aerial platforms. Based around advanced solid-state Lidar technology, the Polyscanner LS1 uses an innovative scanning pattern and focused field of view (FOV) to create a dense point cloud with a detection range of over 200 metres. This latest addition to the Polyscanner family of aerial mapping platforms incorporates PolyExplore’s Polynav 2000 precision GNSS-aided INS (inertial navigation system) technology, featuring a dual-frequency, dual-antenna, quad-constellation PPK/RTK capable receiver with centimeter-level accuracy and a tactical grade IMU. Sensor fusion post-processing software is also included as part of... (read more)

Newly Launched Leica GNSS RTK Rover Equipped with Visual Positioning

Leica Geosystems, part of Hexagon, has unveiled the Leica GS18 I, a versatile, GNSS RTK rover with visual positioning. The GS18 I allows users to capture points of interest from a distance and measure points from the images in the field or in the office. Visual positioning technology – sensor fusion combining GNSS, IMU and a camera – allows users to reach previously inaccessible or obstructed points safely and efficiently. Visual positioning is based on photogrammetric technology with near real-time data processing, allowing surveyors to check the quality of their data while on site. “The GS18 I and the workflow in...

Using the Apache Unmanned Survey Vessel

Techniques in Bathymetric Survey
This paper explores the various features of the Apache USV series for efficient seafloor-level mapping. The CHCNAV hydrographic survey software is used for data recording and analysis. It provides results in the form of 3D models of the ground, contours and depth. (This story is brought to you by CHCNAV) Bathymetry is the study and mapping of the seabed or lake bed. It consists of obtaining measurements of the depth of the ocean or lakes and is equivalent to the mapping of the Earth’s topography. In general, only limited information is known about the seabed and lake beds. Existing maps... (read more)

Emesent Launches Autonomy for Beyond-Line-of-Sight Underground UAV Flight

Emesent has announced a major breakthrough in the journey to fully autonomous flight systems, with the launch of Autonomy Level 2 (AL2) technology for Hovermap, a plug-and-play payload for industrial drones that provides autonomous beyond line of sight, GPS-denied flight. Building on Emesent’s innovative Hovermap simultaneous localization and mapping (SLAM) autonomous flight system, AL2 enables compatible drones to fly beyond communications range and venture beyond line of sight into unmapped areas. The AL2 technology enables companies to rapidly map, navigate, and collect data in challenging inaccessible environments such as mines, civil construction works, telecommunications infrastructure, and disaster response environments. Andrew... (read more)

CHC Navigation Introduces New UAV-Lidar Combination

CHC Navigation (CHCNAV) has launched its new multi-rotor BB4 drone and AlphaUni 300/900/1300 Lidar. The groundbreaking combination of the AlphaUni 300/900/1300 Lidar and BB4 UAV solutions creates one of the most comprehensive and versatile ranges for 3D mapping and geospatial data acquisition in land, air and marine applications. "The purchase of a 3D mobile mapping system is too often constrained to a specific purpose, such as airborne or ground survey. A lot of our customers expressed the need to have a professional Lidar solution that can be used in different scenarios, offering optimal adaptability to their current and future needs,"...

A Commercial Drone Mapping Solution Using the Phantom 4 PPK

Previously, people had to invest more than 30,000 dollars to purchase professional mapping drones and place a large number of control points on the ground to get accurate, survey-grade maps. This situation continued until DJI released the Phantom 4 series of commercial drones with integrated GNSS antenna and high-definition gimbal cameras. This paper proposes a commercial drone mapping solution using the Phantom PPK to significantly reduce control points, and explains the workflow, testing methods and how the results support this level of drone mapping accuracy. (This article is brought to you by Hi-Target and was written by Richard Pan and... (read more)
