Trimble Connect is an open collaboration platform for design and construction that connects project stakeholders with the data they need to inform decisions and improve team efficiency. Project stakeholders can share, review, coordinate and comment on data-rich constructible models, schedules and critical project information in real time — reducing costly miscommunication and improving coordination to keep projects on time and on budget.
In addition to adding new users, the activity on Trimble Connect has shown a considerable increase in collaboration for businesses in the architecture, engineering and construction (AEC) industry.
The number of invitations to collaborate on projects increased 58% in April over the previous month, indicating that users are adjusting to new remote and distributed working dynamics and enabling teams to stay resilient, despite interruptions to their traditional daily routines.
“This is an exciting milestone for Trimble Connect,” said Ray Bagley, business area director for Trimble Connect. “Businesses in the AEC industry need an open, common data environment that allows project stakeholders to unlock the real value of building information modeling (BIM), civil construction and geospatial data. The increased adoption of Trimble Connect in recent months shows us that businesses need reliable, open collaboration more than ever before.”
Trimble Connect’s open API enables data-flow to and from a variety of applications and allows users to customize workflows by integrating with existing enterprise solutions. Users can access project files stored on Trimble Connect directly through a wide range of solutions, including Tekla Structures software, Trimble Access field software, Trimble FieldLink layout software, SketchUP 3D modeling software and ProjectSight construction management software as well as third-party applications.
In 2018 the first-ever European Radionavigation Plan said “It is recognized that [..] GNSS should not be the sole source of PNT information. Alternative PNT systems, not necessarily using radio frequencies, should thus be put in place where the criticality of the application requires it.”

In 2019 the European Space Agency (ESA) published a permanent open call for proposals for positioning, navigation, and timing studies and systems, including those that had nothing to do with space.
“Maritime navigation and port operations are critical for almost every nation,” said Jonathan Turner, one of the MarRINav project team. “As an island nation with a strong maritime heritage, we in the United Kingdom perhaps have an even greater appreciation of this.” Turner is co-founder of the blue economy solutions company NLA International, which led a team of eight organizations cooperating on the project.
While MarRINav focused its analysis on the United Kingdom, the intent was to provide information, and an analysis framework, that could also be used by other nations.
Maritime is one of sectors most dependent upon GNSS, according to the project reports, and a sector with great awareness of GNSS vulnerabilities and their consequences. MarRINav concludes that integrity and resilience are two of the most important parameters for maritime navigation.
Maritime is also one of the sectors most ready to integrate space and terrestrial navigation systems, according to the report’s authors. The International Maritime Organization has already introduced a performance standard for a multi-system receiver, or MSR, that will incorporate a wide variety of navigation signals.
Despite the distractions of Brexit over the last four years, the United Kingdom has been particularly focused on its vulnerability to GNSS outages.
In February of this year the UK government announced it was establishing a virtual National Timing Centre to protect the nation from the risk of GNSS failure, and in March the final MarRINav report was published.
Among the project’s findings are that:
The United Kingdom needs a comprehensive maritime PNT architecture with multiple, diverse sources to ensure continuity of maritime operations
Such a “hybrid solution” could benefit other sectors, especially if non-maritime needs were considered early in the design
New PNT systems should be terrestrial and sovereign
Establishing such a system for the UK has a very positive benefit to cost ratio
Important aspects of the new architecture are E-GNSS (Galileo and EGNOS), Enhanced Loran (eLoran) and the Ranging Mode (R-Mode) of the VHF Data Exchange System (VDES), and complemented by the development of a specific Maritime Receiver Autonomous Integrity Monitoring (M-RAIM) algorithm.
LOCATA or a similar local positioning system should be implemented at UK ports to provide a backup for container operations.
Satelles Satellite Time and Location may have potential, but its utility has yet to be demonstrated for maritime.
ADVA has launched a ePRC optical cesium atomic clock solution to protect synchronization networks during GNSS disruptions. The OSA 3350 ePRC+ offers vital backup for mission-critical infrastructures that depend on satellite-based timing, such as mobile networks and power utilities.
The Oscilloquartz OSA 3350 ePRC+ provides high stability and long life, as well as built-in support for Simple Network Management Protocol (SNMP) . It also meets stringent performance demands as well as the cost points needed for mobile networks transitioning to 5G.
Featuring an all-digital design, the OSA 3350 ePRC+ leverages optical-pumping techniques. It greatly improves performance by providing an extremely stable frequency source.
When used with enhanced primary reference time clocks (ePRTCs), the OSA 3350 ePRC+ delivers holdover for 14 days with an accumulated error of up to 35 nanoseconds. This far exceeds the ITU-T ePRC G.811.1 standard that requires an accumulated error under 70 nanoseconds.
The OSA 3350 ePRC+ also delivers optimum stability for more than 10 years, much longer than the lifespan of high-performance magnetic cesium clocks.
With a fully modular design, the optical cesium solution features a wide range of telecom synchronization output interfaces and supports modern and secured management capabilities with SNMP. It is RoHS-compliant and is fully integrated into ADVA’s Ensemble management and control software suite for operational simplicity and ease of use.

Kaarta, an innovator of real-time mobile 3D reality capture, has announced beta testing on Stencil Pro, a versatile professional-grade mobile mapping platform with dimensional and visual fidelity.
According to a Kaarta press release, “Whether on the road or on a job site, in a warehouse or an office, an underground mine or in the woods, along a utility corridor or a railway, the multipurpose Stencil Pro mobile mapping system is ready to take on the most challenging environments with impressive speed, providing accurate and visually stunning results.”
An all-in-one system to scan, process and view captured data in real time, Stencil Pro offers panoramic high-definition 4K imagery and colorized point clouds. With robust surround-view perception in a wide range of light conditions, Stencil Pro is optimized for both indoor and outdoor performance.
Featuring a 32-line high-density, low-noise lidar with a range of 120 meters (nearly 400 feet) and a data rate of 600,000 points per second, Stencil Pro produces a highly accurate 3D model in minutes.
With an IP65 rating, Stencil Pro is safeguarded against adverse elements such as dirt, dust, fog and rain, making it the ideal tool for infrastructure mapping, mining, forestry, earthworks, construction and other harsh environments. Stencil Pro’s rugged and versatile design is adaptable to many environments, capturing data amidst poor weather, dusty work environments, and below-ground cavities or when mounted on vehicles, locomotives, ATVs and other platforms.
Like all Kaarta systems, Stencil Pro’s simultaneous localization and mapping (SLAM) capabilities means it operates in GNSS-denied areas such as indoor, underground, under canopy, or in urban canyons. However, it is also fully geo-enabled for the many applications such as street, corridor and rail mapping where the addition of a GNSS signal is highly beneficial.
Stencil Pro integrates the Trimble BD-990 receiver, AV-28 antenna and a range of other third-party GNSS antennas. It supports positioning accuracy enhancements through live RTK/NTRIP processing as well as PPK corrections based on data provided by the NOAA CORS network or a user-supplied base station.
GNSS positioning data is used to align and geo-register data, providing global accuracy and further enhancing the fidelity of large area scans and long, linear scan paths. With the ruggedized design, enhanced power capabilities, as well as the option of incorporating the industry-leading SLAM accuracy in addition to – or independent of – geopositioning, Stencil Pro has the scale of traditional mobile mappers for a fraction of the investment.
The onboard GNSS and color cameras are fully integrated into real-time capture, allowing for optimization of collected data as well as flexibility in output. The advantage of absolute positioning and accuracy coupled with 360 degree imaging technologies produces a true color, rich and robust point cloud when needed. If a colorized point cloud is not required, or GNSS is not available, reliance on other sensors is seamless.
“Billions of dollars of commercial real estate transactions, construction projects, infrastructure maintenance and natural resource management decisions rely on understanding existing conditions data,” said Kevin Dowling, Kaarta CEO. “Obtaining up-to-date data for these environments is laborious, time consuming and expensive with current methods. Even in the most challenging scenarios, Stencil Pro rapidly provides the answers needed for managers to make informed decisions.”
Stencil Pro is powered by either 100-240 VAC input (or 12V with an inverter) or using its two hot-swappable batteries which last for up to 3 hours of scanning. Stencil Pro’s intuitive user interface makes data capture and processing simple. The user experience includes one-button scanning, real-time scan monitoring and streamlined post-processing options for maximizing data clarity and usability. Remote operation with a touchscreen monitor allows for mounting Stencil Pro on a multitude of transports. When hand-carried, scan status can be started and stopped with the press of a button.
Stencil Pro is built on Kaarta Engine, Kaarta’s patent-pending approach to solving the SLAM problem. Kaarta’s unparalleled expertise in localization – a result of its deep robotics roots – delivers definitively lower drift error than alternative SLAM systems by an order of magnitude. Kaarta’s proven technology, quality, and accuracy is trusted by AEC, geospatial, natural resource management and autonomous mobile robot professionals worldwide.
Limited quantities of Stencil Pro will be available to ship in June. Those interested in being considered for early access to discuss a specific application, schedule a demonstration or review sample data sets can apply for the Stencil Pro Early Access Program.

Photo: Zonu
The ZonuSkyShot is designed for quick testing during the critical installation phase of an antenna at a new site build or small-cell integration. The compact tester is designed for integrating a Zeno GPS solution, but works as a neutral testing device. SkyShot is a compact GPS receiver that detects the presence of a GPS signal, indicated on the top-panel LED. The receiver can be accessed via the USB port on the base unit, allowing the user to see the available satellites by using the app provided with the system and available at the Optical Zonu website. The receiver can simultaneously track up to 16 satellites while searching for new ones. Because of this, a problem can be found and mitigated when a GPS antenna is installed, rather than when hardware is being integrated further down the line. Close-out of projects can be indicated with screenshots of satellite visibility via the micro-USB port to a laptop.

Earthworks Grade Control Platform version 2.0 features improvements to enable faster return on investment, increase productivity and decrease training time for operators. Horizontal Steering Control for dozers automatically controls the machine to follow any horizontal alignment such as a back of a curb, breakline, roadway centerline or bottom of slope, without operator assistance. Augmented reality for excavators enables users to understand 3D models, cut/fill information, slope data and other bench points and reference points on the in-cab display in context, without the need to interpret complex 2D plans or stakes. A new mastless motor grader configuration gives operators an improved range of blade motion, allowing for machine control in applications where it previously was not possible. Integrated Trimble Loadrite Payload Management displays grade control and accurate payload data on one screen, increasing mass haul productivity and efficiency by preventing underloading, and improving safety by avoiding overloading. Trimble Earthworks is also now available for compact grading attachments with dual GNSS, single GNSS and total station guidance options. The Earthworks Assistant App provides access to Earthworks learning material and documentation, allowing for a shorter learning curve and less downtime for operators.
The addition of advanced tilt and rotation functionality allows Automatic Excavator operators to easily swivel or tilt the bucket with automatic boom control for faster and more efficient excavation. If excavator operators are in situations such as at the top of the slope, grading a long incline and not totally perpendicularly lined up, the added feature makes it easier to position the cutting edge of the bucket to the surface. Operators can excavate more quickly, moving the excavator fewer times with less wear and tear on the chassis. It is also beneficial when navigating around manholes, trenches and tight spaces.

Javad Ashjaee, founder of Javad GNSS, has died in Moscow, Russia. He died on May 30 after a three-week fight with COVID-19.
The news was first reported by a family member on social media. Ashjaee was born in 1949.
“It is with heavy hearts that we share the news of the passing of our founder Javad Ashjaee, a GPS/GNSS pioneer and visionary, on the morning of May 30, 2020, due to COVID-19 in Moscow, Russia,” reports a statement on the JAVAD GNSS website.
The website continues, “Over the course of 37 years, Javad made an incredible and far-reaching impact in the GNSS community. He pioneered the world’s most advanced GNSS technology through a multi-national effort that combined GPS and GLONASS and established more than a quarter century of partnership between Silicon Valley and Moscow. He was always proud of this ‘success story of cooperation.’ Javad was a true industry disrupter long before the term and concept became popular. His whole way of doing business was challenging and disrupting to the status quo.”
Read more about Ashjaee in his own words on the Javad GNSS website, where he describes the founding of his company:
“In 1998 I founded Javad Positioning Systems (JPS) and introduced Legacy, Odyssey and Regency products, followed by HiPer. It was a 76-channel geodetic receiver. Other companies later copied HiPer. Today, many of GNSS receivers look like it. I sold JPS to Topcon, who changed its name to Topcon Positioning System and is a very successful company.
“In 2007, after my obligations to Topcon ended and according to the provisions of our agreement, I founded Javad GNSS and introduced Triumph products. These were 216-channel receivers, integrated with several communication channels. We also introduced their Alpha, Delta, and Sigma versions. We were again the first to offer European Galileo and Japanese QZSS tracking in mass production. Triumph technology has been shown to have the best signal quality and best multipath reduction capabilities against all others tested by the German Aerospace. We also introduced GLONASS inter-channel (group/carrier delay) calibration to 0.2 millimeter which made GLONASS FDMA as good as GPS CDMA. Javad GNSS is growing fast and gaining market share.”
Articles, insight provided by Ashjaee to GPS World
Ashjaee’s nephew Sol Adibnejad provided this biography on his uncle via social media:
Javad was born in 1949 in Qom, Iran. After finishing his bachelor’s degree in electronic physics from the University of Teheran in Iran, he left Iran in 1972 to continue his education at the University of Iowa and got his graduate degrees, a doctorate in 1976. He went back to his native country Iran to teach at the university. He became the chairman of the Department of Computer Engineering at the Aryamehr University of Technology where he founded and managed a UNIVAC-100 computer centre. There, he created the first Iranian microprocessor lab. In 1978 he created one of the earliest student online and interactive registration systems in the world. In a few years and after the 1978 revolution and the political turmoil, things happened and he had to flee the country in 1981.
He went straight back to the U.S. and started the next chapter of his journey in life which led to the pioneering of GPS. He spent the rest of his life designing and manufacturing of many generations of his GPS and JPS products at JAVAD GNSS, JAVAD ArWest and JAVAD EMS in the Silicon Valley. Javad Ashjaee is listed as the primary inventor in 102 granted patents, the last one in April 2020.
Honeywell has been granted a four-year, $99 million contract to help the U.S. Air Force for the embedded GPS and inertial navigation systems (INS) modernization program (EGI-M). Honeywell will provide engineering, manufacturing and development services to the EGI-M program under the sole-source contract, according to the Department of Defense.
Work will be performed in Clearwater, Florida, through April 19, 2024.
The contract is the result of a sole-source acquisition and only one offer was received. The Air Force Life Cycle Management Center, Position, Navigation & Timing Contracting Branch, Robins Air Force Base, Georgia, is the contracting activity (FA8576-20-C-0001).
The COSMIC-1 program ended on May 1, when the last of six tiny satellites were decommissioned. The satellites were launched 14 years ago, and outlived their planned lifespan by 12 years.
COSMIC — the Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC) mission — uses GPS signals to provide a wealth of accurate atmospheric data and improve weather forecasts, according to Laura Snider, University Corporation for Atmospheric Research (UCAR), which ran the COSMIC program.
Meanwhile, the COSMIC-2 program (FORMOSAT-7 in Taiwan) continues. Its six satellites were launched on June 25, 2019, into low-inclination orbits. The mission was launched by NOAA as the agency’s first operational GNSS radio occultation mission.
COSMIC-1 demonstrated the value of GNSS radio occultation (GNSS-RO) to derive vertical atmospheric profiles of temperature, humidity and pressure by measuring the degree to which GPS signals bend as they travel through Earth’s atmosphere.
Weather centers used the high-quality, accurate data to improve forecasts; the data was also used by researchers.
“Throughout its lifetime, COSMIC-1 made an astounding 7 million vertical atmospheric profiles available to the operational forecast centers and research community,” writes Snider. “These data demonstrably boosted forecast accuracy and were referenced in more than 550 peer-reviewed scientific publications. In all, more than 5,000 users from over 100 countries have accessed COSMIC data.
COSMIC-1 was primarily funded by the National Space Organization in Taiwan, where the mission is called FORMOSAT-3. The leading U.S. sponsor on the project was the National Science Foundation. Other U.S. partners included NASA, the National Oceanic and Atmospheric Administration (NOAA), the Air Force and the Office of Naval Research.
UCAR also led the GPS/MET GPS radio occultation mission in the mid-1990s.
The driver, developed by NovAtel engineers, provides an optimized interface enabling users to accelerate autonomous development projects by quickly incorporating NovAtel OEM7 receivers into custom applications.
The driver is available for immediate download through the new NovAtel GitHub repository or as a ROS Binary Package for direct installation.
With the release of a NovAtel-developed OEM7 driver built on ROS, developers can now confidently access the critical data needed to build autonomy algorithms for academic investigations, ride-share programs, and other applications.
Data from numerous sensors can be combined to help move projects into higher levels of autonomy faster without the need to adapt community-developed drivers. Tested using the Hexagon | AutonomouStuff platform, the driver ensures that the data received accurately reflects the output provided by the receiver, while also giving users the ability to record raw data for post-processing.
“We are excited to introduce our first purpose-built driver powered by ROS to the GitHub community. Its development is a result of collaboration between NovAtel and AutonomouStuff in support of Hexagon’s Smart Autonomous Mobility (SAM) initiative, unveiled at CES 2020 in Las Vegas,” said Miguel Amor, chief marketing officer, Hexagon’s Autonomy & Positioning division. “The SAM portfolio is a comprehensive solutions platform that brings together all the necessary sensors, software and services to make autonomous driving possible.”
The new driver is available for download on the NovAtel GitHub repository.
