SURVEYING INSTRUMENTS

Here's what Leica says about the GS18 I:

​

"Introducing Leica GS18 I, a versatile, survey-grade GNSS RTK rover with Visual Positioning. Designed for surveying professionals to measure points which previously could not be measured with a GNSS rover easily and accurately. Now, you can quickly capture the site in images and measure points from them, either in the field or later in the office.

​

Sensor fusion of GNSS, IMU and a camera come together to create Visual Positioning technology, resulting in a GNSS RTK rover so powerful that it enables you to measure what you see. GS18 I has all the functionality of the Leica GS18 T: in addition to Visual Positioning, users can for example map points with either tilted or levelled pole.

​

• Measure points with obstructed view to the sky more efficiently and easily.

• Capture points you couldn’t reach before with a GNSS rover.

• Gain more flexibility and control, with no need to use additional time-consuming equipment.

• Map hundreds of points with survey-grade accuracy within minutes.

• Capture the scene quickly and decide later, what should be measured – even if the scene subsequently changes or disappears.

• Tap on an image to measure a point in the field or in the office.

• Quick and thorough so you catch every detail."

"Leica GS18 T – The world’s fastest GNSS RTK rover

Introducing the world’s fastest and easiest-to-use GNSS RTK rover, the Leica GS18 T. Now you can measure any point faster and easier without the need to hold the pole vertical.

This latest innovation combines GNSS and inertial measurement unit (IMU) being the first true tilt compensation solution that is immune to magnetic disturbances and is calibration-free. The GS18 T works directly out of the box.

Save up to 20 per cent over conventional surveying practices due to the fact that no time is wasted by levelling the bubble. Focus on your surroundings and not the bubble to measure points that previously could not be measured. Avoid timeconsuming auxiliary methods with true tilt compensated surveying. You will stake out more efficiently and conveniently than ever before with increased speed, safety and comfort. Watching the bubble is simply no longer needed.

The GS18 T GNSS RTK rover is part of the Leica Geosystems self-learning GNSS series. It seamlessly combines with Leica Captivate field software and Leica Infinity office software, continuing the powerful and immersive Leica Captivate Experience."

Here's what Stonex says about the S990A:

"High Performance with Atlas® and IMU

Stonex S990A is a 800 Channels GNSS receiver characterized by a new feature that enhance the performances of field surveys.

The new IMU System allows tilted measurement (TILT) up to 60°: quick initialization, fast and precise survey.

S990A Receiver is equipped with all important connectivity capabilities: Bluetooth, Wi-Fi, UHF radio and 4G modem. The internal battery of 10.200mAh allows to work for 9 hours and can be recharged via a type-c connector.

The color touch display and the WebUI are an easy and fast way to have the complete control of the receiver.

Thanks to aRTK function and Atlas® correction service, Stonex S990A is also able to work in particularly difficult areas. Atlas® delivers world wide centimeter level correction data through L-band communication satellites.

1PPS can be applied to scenarios that require precise synchronization time to ensure that multiple facilities work together or that use the same parameters for system integration based on precise time.

Stonex S990A with IMU system makes reliable every measurement, both survey and the stake out jobs, and makes extremely faster the acquisition of points: up to 40% of the field work time can be saved!"

Here's what Septentrio says about the PolaNt ChokeRing B3/E6:

"Built of aluminum, the ChokeRing B3/E6 is a high precision multi-frequency antenna for reference stations. It is recognized for its durability in harsh conditions and reliability. Featuring low-noise amplifiers, the ChokeRing B3/E6 is enabled for multi-frequency reception (GPS, GLONASS, Galileo, BeiDou, NavIC, QZSS and SBAS) and to mitigate multipath by attenuating reflected GPS signals thus significantly improving the reliability and accuracy of your reading.

Key features

• Support current and planned GNSS signals from GPS, GLONASS, Galileo, BeiDou, NavIC, QZSS and SBAS

• BeiDou B3 and Galileo E6 capable

• High phase center stability

• IGS calibration available with or without radome"

Here's what Carlson says about the BRx7+:

​

"Best-in-class RTK performance is provided by the Athena GNSS engine, supporting multi-frequency GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS, and Atlas L-band capability. In addition, the BRx7 uses proprietary SureFix™ technology to provide a high fidelity quality indicator of the RTK solution, allowing users an extremely high confidence in their current accuracy.

​

Additionally, the BRx7 provides RTK baselines up to 50 km with fast acquisition times when used with Carlson Listen-Listen, as well as UHF, spread spectrum, cellular, Bluetooth, and Wi-Fi wireless communication. Well suited to a variety of operating modes, the BRx7 can be deployed as a powerful base with additional access to BeiDou phase 3 satellites in a base-rover setup, or as a lightweight, powerful network rover.

The smart antenna comes with a dual-band radio module that is capable of both 400 MHz and 900 MHz operation. This allows for the long range capability of the UHF 400 MHz signal plus the ability to switch to the 900 MHz frequency-hopping spread spectrum (FHSS) signal for better performance in noisy radio environments. The BRx7 introduces an all-new INS-based sensor fusion platform to support enhanced tilted pole measurements for land survey applications. This new design allows for easy calibration, is immune to magnetic interference, and is extremely reliable in virtually any environment."

Here's what Leica says about the GS16:

​

"The Leica Viva GS16 is the most compact and powerful, self-learning GNSS smart antenna. Working with the leading RTK technology, the Viva GS16 meets the highest standards in measurement excellence with RTKplus and SmartLink. The growing number of signals from an ever increasing satellite constellation demands a GNSS receiver to be smarter than ever before. RTKplus intelligently adapts to changing conditions by selecting the optimal signals to deliver the most accurate positions. Work more efficiently and in more challenging environments than you’ve ever worked in before.

​

Enjoy uninterrupted accurate positioning even when your local correction service is unavailable due to obstructions or lack of cellular coverage with the global SmartLink service. Even when no reference data is available, work fully remotely with SmartLink."
