Viametris has been developing SLAM-based scanning systems for more than 10 years, including the iMS3D, a full indoor mapping system and the VMS3D, a car-based mapping system.
The bMS3D-360 has been designed for the most challenging environments where GNSS is not accessible (indoor) or highly perturbed (urban canyons, forest, etc.). The surveyor starts the system, checks on a tablet that the GNSS and inertial information are computed, and starts the survey.
Back at the office, the user launches the INS/GNSS post-processing software to increase orientation and position accuracy, and then uses the Viametris software to georeference and colorize the point cloud.
Collected data are ready to be imported into common design software. This workflow (from collection to plan drawing) is seven times faster than a traditional method.
The bMS3D-360 offers a 360-degree camera, which greatly simplifies the treatment work. When navigating in the point cloud, the user opens a unique picture of the 360-degree scanned environment instead of looking at four different camera points of view.

The Ellipse2-D from SBG Systems is a compact inertial navigation system integrating an L1/L2 GNSS receiver. This industrial-grade INS computes roll, pitch and heading as well as position because of its embedded Extended Kalman Filtering.
In real time, Ellipse2-D orientation data are used to correct the equipment attitude and help the SLAM computed heading. The embedded GNSS receiver provides absolute positioning to the point cloud as well as altitude constraint.
When the GNSS faces sources of disturbance, the INS maintains the trajectory were the SLAM technology is limited.
SBG Systems has released the Navsight marine solution, a full high-performance inertial navigation solution designed to make surveyors’ tasks easier in both shallow and deep water.
Navsight consists of an inertial measurement unit available at two different performance levels (from shallow to deep water). According to SBG Systems, the Navsight marine solution is based on 10 years of the company’s experience in marine inertial sensing products.
Whether the IMU comes with a surface or a subsea enclosure, they are all lightweight and easy to install, the company said. Navsight connects to any computer, with no software installation. Once connected through Ethernet, the web interface guides the user to configure the solution.
A 3D view of the boat shows the entered parameters so that the user can check in real time the installation. Navsight allows quick installation and initialization thanks to new mechanical calibration module. The embedded filtering controls and validates lever arms and antenna alignment during this procedure.
Navsight Marine Solution provides high-performance motion and navigation data as well as a real-time heave accurate to 5 cm, which automatically adjusts to the wave frequency, SBG Systems said.
To allow surveying when wave frequencies are large or complex, Navsight comes with a delayed heave feature resulting in a heave accurate to up to 2-cm computed in real-time with a little delay.
If higher performance is required, the surveyor can count on SBG INS/GNSS post-processing software named Qinertia. By processing inertial and GNSS raw data forward and backward, Qinertia greatly increases accuracy especially during GNSS outages; it also fixes set up mistakes.
Highly versatile, Navsight comes as a Motion Reference Unit, providing roll, pitch and heave or as a full navigation solution with embedded tri-frequency GNSS receiver, or using an external one. Fusing inertial data with satellite position in real-time, Navsight INS offers continuous position in all conditions, such as surveying under a bridge, or during a GNSS outages due to coastal infrastructures (buildings, harbor cranes, etc.).
The Navsight Marine Solution supports RTK and every precise point positioning service (Marinestar, TerraStar, etc.). It is compatible with the main hydrographic software such as Hypack, QINSy or Teledyne PDS for seamless integration into existing workflows.
Navsight is ITAR-free. All models are available for order. Ordering information and delivery time are available from SBG Systems representatives and authorized SBG Systems dealers.
The Hibiki processors can take input from up to four frequency GNSS signals simultaneously.
The Hibiki front-end can process up to four GNSS signals for software receivers. (Image: Lighthouse)
The Japanese Quasi-Zenith Satellite System (QZSS) broadcasts GNSS signals in four frequency bands: L1, L2, L5 and L6. Similarly, GPS and GLONASS broadcast in three bands, and the European Galileo and Chinese BeiDou systems broadcast in four bands.
However, many conventional front-ends process only two bands at the same time, and cannot be used for highly specialized applications such as processing multiple signals with different frequencies at the same time.
The Hibiki front-end processor was designed to answer to this GNSS technology demand and is able to process up to four frequency bands simultaneously, the company said.
Hibiki has a high data transfer rate performance using USB 3.0, stably transmitting signal data to the host computer up to 50 million samples per second. This high sampling frequency is much greater than conventional front-end processors, improving L5 signal-receiving performance and reducing multipath.
Wingtra has officially launched the WingtraOne PPK high-precision mapping drone. Wingtra said its drone, which features vertical take-off and landing, is designed to set a new benchmark for large-scale surveying and mapping applications.
WingtraOne PPK offers large area coverage, ultra-high accuracy and brilliant image resolution. It features an advanced PPK module and high-quality cameras like the 42-megapixel full-frame camera Sony RX1RII, it is now possible to reach down to 1-centimeter absolute accuracy in aerial mapping.
To prove this accuracy claim, the Wingtra team performed test flights in a gravel quarry. The process was documented and is now explained in a white paper on the company website.
Conventional drone mapping on centimeter accuracy requires ground control points (GCPs) to correct the final map. Besides requiring additional surveying equipment and being extremely time consuming, setting up GCPs might be downright risky or just not possible in the area of interest.
More advanced solutions achieve similar levels of accuracy by using GPS correction technology for the georeferencing of the aerial imagery: namely RTK (real-time kinematics) or PPK (post processed kinematics).
RTK requires real-time base station connectivity and corrects GPS signals during the flight, while PPK corrects them after the flight and therefore offers greater robustness and consistency.
Moreover, PPK is independent from base stations or base station networks. It is highly reliable, accurate and time saving to use, Wingtra said. Neither special flight preparations nor intensive post-processing steps are required to achieve down to 1-cm accurate aerial maps.
In mid-2017, Talen-X and Skydel engineers began to conceptualize a GNSS simulation system emanating from their BroadSim platform for the purpose of fortifying anechoic chambers.
Over the next six months, Talen-X and Skydel designed, built, tested and delivered an anechoic chamber simulator capable of simultaneously generating multi-GNSS jamming and spoofing signals.
BroadSim Anechoic can be used to support a wide variety of operational tests.
“Our new Anechoic Chamber solution will radically change the way in which mission critical platforms and systems are tested because we are enabling our customers to create real-world threats,” said Talen-X Chief Technology Officer Tim Erbes said. “Not only will BroadSim Anechoic be able to emulate real-world threat scenarios, it will be easier than ever before to create and simulate these environments.”
BroadSim Anechoic is used to test GNSS spoofing and jamming in an anechoic chamber. The BroadSim Controller is at the heart of the system running Skydel’s SDX software suite. Using SDX, users can create advanced scenarios that include both jamming and spoofing signals.
The 16 software-defined radios (SDRs) each with dual transmit ports (32 total outputs) can be configured to output GNSS or jamming signals, giving users flexibility to run test after test. The transmit chains include the hardware to power 16 dual-frequency antennas. The included GNSS receivers allow users to monitor the environment inside the chamber, providing confidence that tests are running correctly.
The BroadSim Anechoic can also be used in controlled radiation pattern antenna (CRPA) testing. Many ground-, airborne- and water-based platforms are transitioning to using CRPAs because of their added jamming resiliency and significant tracking advantages in degraded environments.
Validation and real-world testing is critical to understanding and characterizing the mitigation these antennas can add in highly degraded areas. By using BroadSim Anechoic, users have the ability to create representative jammers with real-world characteristics (modulations, frequencies, angles, power levels, etc).
“Skydel developed an innovative approach for time offset calibration between multiple transmitting antenna using a COTS Software-Defined Radio (SDR),” said Skydel Solutions Chief Technology Officer, Iurie Ilie. “This approach allows for very precise measurements and adjustments (better than 100ps) to be done automatically before simulation start. At the same time, transmitting signal power is automatically adjusted to keep the power offset at receiving antenna better than 0.1dB.”
BroadSim Anechoic takes advantage of state-of-the-art software defined radios (SDR) for RF up-converting while signal IQ generation is done using high performance commercial-off-the-shelf (COTS) graphics-processing units (GPU). The ability to generate the IQ data in software (using the GPU) as opposed to hardware (FPGA) significantly reduces the cost while maximizing capability, value, and time to market.
BroadSim Anechoic has the capability of powering up to 16-dual frequency antennas requiring 32 RF transmit outputs. The architecture used for this system required the ability to receive signals in a manner such that precise processing could be done on the receive signal.
The SDR selected for this application has one receiver channel for every transmit channel giving BroadSim Anechoic 32 RF receive ports. Innovative software techniques have been developed enabling the accurate time and power calibration for each antenna transmit chain using the SDR receive ports.
SuperSurv’s NTRIP solution is being enhanced to adopt more RTCM versions and provide a better GNSS positioning service. NTRIP (Networked Transport of RTCM via internet protocol) is a protocol to send GNSS-related data through the internet, which enables users of differential GPS or network real-time kinematic (RTK) to get correction parameters after connecting to the internet. The correction parameters can be used to calculate a more accurate GNSS location. Supergeo’s product team is developing the support for RTCM 3.1, including Types 1021 and 1023.
The scalable A222 GNSS smart antenna is designed for both agriculture and basic indicate systems markets, as well as other markets requiring flexible positioning.

It adds a system component so that tractor and farm equipment manufacturers can deliver their own guidance and control solutions to their customers. Designed to excel in challenging environments, the A222 uses Hemisphere’s Athena RTK engine and is Atlas L-band capable. It is easy to mount and customizable. Its dual-serial, CAN and pulse output options are compatible with almost any industry-standard interface. Because the A222 is Atlas-capable, it has the ability to use the new Atlas AutoSeed technology. Atlas AutoSeed allows users to suspend Atlas use for any period, and upon returning to their last location, AutoSeed rapidly re-converges to a high-accuracy converged position. A222 comes pre-configured with Atlas Basic activated.

This includes IoT-based applications that historically relied on GPS, with its high rate of power consumption, as well as Wi-Fi and Bluetooth with their added size, cost and network complexity.
Enhancements to the SyncServer S600 series of time servers and instruments improve time synchronization over enterprise Ethernet networks and supply timing signals for improved military radar operations and satellite uplink communications. The SyncServer S600 series also meets the timing and synchronization needs of the rapidly evolving networks of enterprise and financial customers, particularly for compliance purposes such as the European MiFID II directive, which specifies highly stringent time accuracy requirements for stock trading systems. The latest release includes support for the IEEE 1588 multiport, multi-profile Precision Time Protocol (PTP), which allows the S600 to operate as an independent grandmaster clock on each Ethernet port — delivering cost savings and network deployment flexibility to customers. This is coupled with a new 10-GbE interface to easily interoperate with a wider variety of network and stock trading topologies.

Esri, the spatial analytics company, has publishedThe GIS 20: Essential Skills, Third Edition, a book designed to quickly prepare those who need to use a geographic information system (GIS).
The GIS 20 is aimed at readers who are new to or unfamiliar with GIS, such as a professional interested in using the technology on the job to conduct analysis and create maps, or a student majoring in a subject other than GIS who could benefit from geospatial knowledge.
Avoiding a focus on the inner workings of a GIS and sticking instead to teaching the tasks and functions most frequently and commonly used, this quick-start guide provides clear, step-by-step instructions on how to do common GIS tasks.
These include downloading shapefiles and using essential tools in the software, preparing data for a map, geocoding addresses, making thematic and other types of maps, mapping latitude and longitude points collected with a GPS, using aerial photography in maps, and publishing maps.
Author Gina Clemmer is president of New Urban Research, Inc., a social research and training company based in Portland, Oregon. She has spent her career teaching everyone from executives in New York City to residents of fishing villages in Alaska to how understand the core concepts and use the tools of GIS for decision-making.
“This book is an extension of my passion to help everyday people quickly learn the fundamentals of ArcGIS,” Clemmer wrote in The GIS 20. “Once you see the power of GIS and see that you yourself can create maps easily, you simply can’t unsee it. GIS will change the way you think about presenting data and solving problems.”

The antenna pairs with dedicated short-range communications (DSRC) devices to enable vehicle-to-vehicle, and vehicle-to-infrastructure communications.
Traditional aftermarket antennas require drilling holes or passing cables through window and door openings, which risks damaging vehicle seals.
Danlaw’s dual-radio, glass-mounted antenna eliminates the risk of damaging the vehicle by using a coupling pair-to-pass DSRC signals between the vehicle’s interior and exterior.
The easy-to-install antenna can be mounted on the rear, front or side windows using automotive grade glass adhesive. This flexible installation allows the shortest cable route to the V2X device, reducing signal losses due to cable length, the company said.
“Our customers running pilot programs want to install V2X DSRC systems on vehicles with best-in-class RF performance without modifying their cars,” said Scott Morell, Danlaw’s vice president of engineering. “Combined with our Aftermarket V2X Safety Device, this enables V2X capabilities to be installed on vehicles simply and easily.”
The antenna enhances Danlaw’s Connected Vehicle portfolio which includes an aftermarket safety device (ASD) and V2X development tools.
The ASD has been selected by pilot programs supporting multiple applications, including critical safety advice, driver access solutions, and real-time road condition and congestion information.
Danlaw development tools include the OmniAir-certified Mx-DSRC Conformance Test System and Mx-Drive Mobility Simulator.
Detailed specifications for the antenna are available.
