The Best Leica Laser Scanners for Your Construction Business

Leica Laser Scanners technology has become a staple around the globe; arguably, almost all industries benefit from this technology, and even if you haven’t encountered it in real life, you must have seen it in the movies beginning in the 20^th century. 

Leica 3D Laser technology dates back to the 1960s when the scanners developed during this period were characteristic of projectors, lights, and cameras to perform their designated tasks accurately.

Enter the 1990s, the construction industry’s use of advanced laser scanners gained much more traction than anticipated. Therefore, laser scanners collect high dynamic range and image data to help improve efficiency and productivity.

In a world where transparency rules, a space where you need the best technological innovations to ensure that things run efficiently and effectively at all times, you need the best technical elements to get things running. Whether in construction or the oil drilling business, necessary technologies will give you an upper hand in your industry.

In this case, you need the best Leica devices for the best performance in your construction business, specifically Leica Laser Scanners. So, what exactly are these technologies, and how do they work?

What is GNSS, and how does it work?

GNSS or Global Navigation Satellite System refers to satellites’ constellations to provide specific signals from space to transmit positioning and timing data directly to GNSS receivers. These receivers will then make use of the data collected for location determination.

Thanks to the design of GNSS, they offer global coverage, hence more accuracy and a high level of performance.

GNSS follows four main criteria – accuracy, integrity, continuity, and availability for assessing the GNSS performance.

In terms of accuracy, GNSS’s performance is the difference between a receiver’s actual position and the measured performance, time, or speed.

Integrity – this means that the GNSS system can offer a threshold of confidence, which means that an alarm would be raised in the event of an anomaly in data positioning.

Continuity – The GNSS system is capable of working fully without any interruptions.

Availability refers to GNSS’s percentage of time within which the signals received by GNSS receivers can fulfill results above the accuracy, continuity criteria, and integrity of the data.

The European GNSS or E-GNSS features the use of satellite signals from the Galileo constellation and augmentation services, all offered by EGNOS. Then you have the European GNSS agency of GSA responsible for managing the European GNSS.

These happen through the GNSS Service Centre or GSC, which offers support for providing a single interface for all Galileo users.

It’s also worth noting that GSA contracted the operations of EGNOS and its service providers to ESSP (European Satellite Services Provider), enabling a single interface for all EGNOS users through the use of EGNOS user web support.

So, how does GNSS Work?

While GNSS satellites vary in design and age, their overall principle of operation remains the same. These satellites work by transmitting two carrier waves on their L-Band, L1 and L2. These carrier waves work by sending information to the Earth from satellites.

Most GNSS receivers feature an antenna and a processing unit. The antenna works to receive satellite signals, and the processing unit processes and makes sense of the signs received. But for an accurate determination of the receiver’s position, GNSS calls for the use of at least three satellites to ensure the accuracy of the information collected.

GNSS’s satellite orbits Earth every 11 hours, 58 minutes, and 2 seconds at its medium-orbit altitude to make all these possible. Each of the satellites transmits coded signals containing the details of the satellite’s actual position and orbit details and a stable time stamp collected from the atomic clock.

Then you have the time information broadcast, which runs as codes by the satellite. These codes transmitted by the satellites allow the receiver to determine the actual time for the broadcast signals continuously. These signals collected contain data used by the receiver to compute the precise location of the satellites while adjusting the satellites for accurate positioning.

Next, the receiver uses the time difference from the satellite signals reception and the specific broadcast time to compute the range or distance from the receivers to the satellite.

Once the receiver has the satellite’s precise position concerning the other satellites, it will translate its position into the Earth-based coordinates system, hence the latitude, longitude, and height positioning.

So, what makes GNSS very accurate/ precise?

The GNSS receivers precisely determine satellite and location positioning based on four factors mentioned above – longitude, latitude, height, clock error, or any other navigational solution from the receiver based on the computation of the distance from the satellites.

Signal transmission is made possible by accurate atomic clocks in the satellites. As a result, these receivers calculate the total time for the information collected from the satellite in question to reach the GNSS receivers.

For position determination, the GNSS receivers must be in the line of sight between the four satellites and the receiver’s antennas. And by using more receivers will be easy for you to improve the receiver’s position solution.

The only catch is that very few receivers can use the extra satellites. But by synchronizing the local clocks with the system’s very accurate atomic clocks on their satellites.

With high time precision, GNSS systems are ideal for use in cellular systems, financial networks, and the synchronization of power grids.

Is GNSS better than GPS?

GNSS, which represents a term encompassing all the global satellite positioning systems, works differently. Still, importantly, it’s worthwhile to mention that GPS is a component of GNSS.

Specifically, GPS refers to the NAVSTAR Global Positioning System, representing the constellation of satellites developed by the US DOD (Department of Defence). Though initially designed for use by the military, GPS was later accessible to civilians for continuous global positioning and global timing information under all weather conditions.

In short, GPS and GNSS work together or collaborate for the global location positioning needed anywhere on Earth.

However, the main difference between these systems is that while GNSS is a GNSS-compatible device using navigational satellites from all other systems beyond GPS, hence the highest level of accuracy plus reliability, not all GPS receivers are GNSS-compatible. As a result, the level of accuracy for GPS might be imperfect at other times.

That said, GPS and GNSS have the following in joint. They both have space/ satellite segments, a ground segment for ground control stations, and a user segment for GNSS and GPS receivers, not to mention the exact location of the satellites at any time in question.

The satellites will send radio signals toward the Earth. These signals will be picked by GPS and GNSS receivers; then, you have ground control stations for monitoring GNSS and tracking satellites, updating satellite positioning with ease.

How do Leica 3D Laser Scanners work?

3D laser scanners and, subsequently, laser scanning technology, refer to the non-contact and non-destructive technology designed to digitally capture the shape of the physical questions using laser lights.

Leica 3D Laser will then create point clouds as data from surface objects. 3D scanning allows for capturing physical objects in their exact sizes/ shapes as digital 3D representation systems.

The Leica 3D laser scanning process follows these steps:

• Data acquisition through Leica 3D laser scanning. In this case, the object to be scanned is placed on the digitizer’s bed. This is made possible by specialized software that will drive laser probes above the object’s surface. The laser probe will then project the line of laser light on the digitizer’s surface, where two sensor cameras continuously record the changing shape and distance of the laser lines running in 3D.
• Resultant Data. Next up, the object’s shape appears as millions of points or point clouds on your computer monitor while the laser runs around to capture the object’s shape. This is a superfast process that gathers up to 750,000 PPS.
• Modeling Choice, depending on the available applications. The collected cloud data files are then registered and merged into a 3D representation of the object and the post-professed image using specific applications.
• Inspection of Point Cloud data. The scanned data is compared to the CAD nominal data from the designer, and the result of this process is delivered as color map deviation reports in a PDF format.
• CAD modeling for Reverse Engineering. It would be best to use specialized software to create the fastest way of making the most accurate and very automated 3D digital data through reverse engineering. The point cloud data is important here as it allows for creating 3D CAD models as part of the model’s geometry. The CAD models allow for precise reproductions of scanned images and are also used to correct imperfections.

Laser design further allows for the provision of surface models or solid models for the best results needed.

Leica 3D laser scanning and Leica Total Stations are important for developing accurate designs through simultaneous models in the building phase.
