Geospatial Monitoring Harnessing the Power of GNSS

Global Navigation Satellite Systems (GNSS) encompass various satellite constellations in Medium Earth Orbit (MEO). Each satellite in these constellations transmits positioning and timing data to GNSS receivers on Earth. By utilising multiple constellations, GNSS-enabled devices can enhance accuracy through time synchronisation and the geometric principle of triangulation. 

Selecting the Right Technology is Crucial

In the rapidly evolving field of geospatial monitoring, selecting the right technology is crucial for achieving the highest levels of precision and accuracy. At the heart of this innovation lies GNSS, or Global Navigation Satellite Systems, a cornerstone technology that enables a wide range of applications, from navigation to critical infrastructure synchronisation. This blog delves into the mechanics of GNSS, compares it with different methodologies, and highlights how we can leverage GNSS to offer unparalleled advantages in geospatial monitoring.

Geospatial Monitoring in Mining and Civil Infrastructure

Geotechnical Engineers, Monitoring Consultants, and Design and Monitoring Engineers in mining and civil infrastructure are constantly seeking more efficient, safe, and sustainable monitoring solutions. While traditional methods like radar, tiltmeters, inclinometers, and total stations have been the go-to for site monitoring, integrating advanced GNSS-based technologies like Kurloo can significantly enhance these efforts.

By incorporating Kurloo Technology into monitoring strategies, these professionals can achieve greater spatial precision and comprehensive 3D displacement data. This integration not only improves operational efficiencies and safety but also promotes sustainable practices through enhanced environmental awareness. Leading mining conglomerates like BHP and Anglo American are already emphasising the importance of innovative monitoring solutions to meet their sustainability and safety goals. By adopting Kurloo Technology, engineers can align with these industry leaders in driving forward-thinking and responsible monitoring practices.

Understanding GNSS: The Backbone of Modern Navigation

How GNSS Works

The mechanism behind GNSS is both intricate and fascinating. Satellites orbiting Earth induce a delay or duration for signals to travel from the satellite to the receiver. This delay is used to determine the distance between the satellite and the receiver. The receiver then employs trilateration, a technique that calculates distances from multiple satellites to pinpoint its exact position.

For accurate trilateration, a minimum number of satellites is required. Moreover, receivers must continually adjust for atmospheric effects, such as those in the ionosphere, to ensure data precision. GNSS operates seamlessly to provide positioning, navigation, and timing services, enabling a wide range of location-based applications.

Comparing Geospatial Monitoring Technologies

When it comes to geospatial monitoring, several technologies vie for attention, each with its own set of strengths and limitations.

1. Tiltmeters and Inclinometers

Tiltmeters and inclinometers are known for their excellent precision. However, they are limited in spatial dimension as they only measure tilt angles and cannot capture full 3D displacement. This restricts their application in comprehensive geospatial monitoring.

2. LiDAR and Photogrammetry

LiDAR and photogrammetry technologies rely on GNSS for positioning, achieving accuracy within a few centimeters, depending on the setup. While these methods offer high-frequency measurements, their installation and configuration are complex. They typically require a surveyor with in-depth knowledge to set up and maintain, and they are dependent on line of sight. This dependency limits the distances that can be measured and makes them susceptible to environmental conditions that can disrupt measurements.

3. Total Stations

Total stations can offer millimeter precision and, when automated, provide a very high frequency of measurement. However, like LiDAR and photogrammetry, their installation and configuration are complex and require skilled surveyors. They also rely on line of sight, which can be a significant limitation in various scenarios.

4. Radar

Apart from being one of the most expensive methods, Radar technology is highly effective for monitoring surface displacement and deformation, especially over large areas. It operates by emitting radio waves and measuring the time it takes for them to return after bouncing off the target surface. Radar can provide high-frequency measurements and is less dependent on weather conditions compared to other optical methods. However, its precision can be affected by the roughness of the target surface, and it may not offer the same level of accuracy as GNSS-based systems. Additionally, while radar is valuable for broad-area monitoring, it requires careful calibration and can be complex to integrate with other monitoring systems.
