Our Technology

We offer an innovative range of advanced equipment tailored to your unique needs. Partner with us to benefit from the applications of our AT-InSAR and GNSS technology solutions to transform your monitoring capabilities.

INSAR

InSAR (Interferometric Synthetic Aperture Radar) maps ground movement using radar images taken from satellites. Unlike visible light, radar can penetrate clouds and works in the dark, allowing continuous tracking of ground deformations in any weather and at night.

GNSS

A Global Navigation Satellite System (GNSS) is a network of satellites that deliver positioning, navigation, and timing (PNT) services. GNSS satellites orbit Earth, broadcasting data on their location and timing to radio receivers, which decode these signals to determine the receiver's position on the ground.

How We Deliver Precise Positioning from Space

Our Approach

Leveraging advanced InSAR for surface monitoring, and GNSS for location and navigation, we combine both to deliver reliable, trusted data - transforming raw information into actionable insights.

Surface Monitoring with InSAR

Geospatial Ventures uses Synthetic Aperture Radar (SAR) technology to capture precise surface data. SAR-equipped satellites emit microwave pulses, measuring their reflection to provide reliable data, even in challenging weather conditions, such as clouds or rain. By analysing the amplitude and phase of these signals, we gain critical insights into the Earth's surface. Through Differential InSAR, we compare images taken at different times to detect and measure surface changes, including ground movement, with exceptional precision.

GNSS for Location and Navigation

Geospatial Ventures uses GNSS technology to determine precise location data. By receiving signals from satellites orbiting Earth, GNSS calculates position using trilateration, measuring distances from at least four satellites to pinpoint an exact location. With connections to four or more satellites, GNSS provides 3D positioning (latitude, longitude, and altitude), making it essential for navigation, mapping, and real-time tracking in dynamic environments.

Enhancing InSAR Resolution with Multi-Image Analysis

Geospatial Ventures enhances traditional InSAR techniques through advanced multi-image analysis. While standard methods rely on two images, atmospheric interference can affect accuracy. Our approach uses multiple SAR images over time to mitigate these errors, achieving millimetric-level precision and ensuring reliable results for infrastructure monitoring and hazard assessment.

Strengthening GNSS Accuracy with RTK

Geospatial Ventures enhances GNSS precision through Real-Time Kinematics (RTK), achieving centimeter-level accuracy by using ground station data to correct satellite signals in real time. Additionally, we leverage GNSS satellites equipped with high-precision atomic clocks, ensuring highly accurate time synchronization. This advanced technology allows us to provide exceptional positioning and timing capabilities for a wide range of applications.

Geospatial Ventures combines the power of InSAR and GNSS technologies to deliver precise, multi-dimensional geospatial monitoring. InSAR detects ground and structural movements with millimeter-level accuracy over large areas, providing valuable insights into potential risks and changes. GNSS, with its point-specific accuracy, complements InSAR by offering continuous, real-time location data.

This combined approach allows for both wide-area monitoring and localized stability assessments, making it invaluable for infrastructure, construction, and environmental management. By integrating additional terrestrial sensors, we enhance real-time monitoring and accuracy, delivering robust, actionable data for proactive decision-making. Together, InSAR and GNSS offer a comprehensive view of ground behavior, enabling better risk mitigation and strategic planning.

Applications of GNSS and InSAR

The Value of Geospatial Technologies in Your Field

GNSS and InSAR technologies are highly relevant to your industry, offering a broad range of applications both individually and in combination, providing valuable insights and solutions tailored to your specific needs.

Comprehensive Infrastructure Monitoring (Buildings, Roads, Railways, Energy, Water, Gas, Pipelines, etc.)

InSAR enables precise monitoring of infrastructure, detecting structural movements and ground deformations over time. It provides insights into risks from subsidence, construction activities, and environmental factors, improving maintenance planning and asset management. GNSS enhances location accuracy, ensuring precise navigation and real-time positioning, which supports efficient monitoring and coordination across extensive infrastructure networks. The combination of both technologies ensures a comprehensive, cost-effective solution for infrastructure management and safety.

Transportation System Management

InSAR offers continuous, non-intrusive monitoring of transportation systems such as railways, motorways, and roads. It detects subtle ground movements that may affect infrastructure stability, providing early warnings for potential risks. This reduces the need for physical inspections and minimises operational disruptions. GNSS enables accurate real-time location tracking, optimising maintenance schedules and improving the overall reliability of transportation networks. Together, InSAR and GNSS ensure proactive monitoring, leading to safer, more efficient transportation systems.

Urban, Greenfield, and Brownfield Site Planning and Development

When planning urban development or assessing greenfield and brownfield sites, InSAR provides valuable data on land stability, identifying potential risks such as subsidence or shifting ground. This supports better decision-making in site selection and development planning.

Onshore Oil, Gas, and Groundwater Monitoring and Extraction

InSAR supports monitoring ground movement and infrastructure stability in onshore oil, gas, and groundwater extraction sites. It detects subtle shifts that could impact operations, enabling timely maintenance and risk management. GNSS offers precise location tracking for operations, enhancing navigation and real-time monitoring. The integration of both technologies ensures comprehensive surveillance of extraction sites, optimising operations while minimising environmental risks and ensuring long-term sustainability.

Mining Subsidence Reporting and Analysis

InSAR is a critical tool for monitoring mining-induced ground movements, detecting subsidence, and assessing the stability of surrounding areas. It enables continuous, real-time monitoring of mining operations and surrounding infrastructure, supporting risk assessment and operational management. GNSS improves navigation accuracy within mining sites, facilitating efficient resource extraction and ensuring the safety of workers and equipment. Together, these technologies provide comprehensive monitoring, enhancing operational efficiency and environmental protection in mining activities.

Monitoring of Inaccessible and Restricted Areas

InSAR allows for the remote monitoring of inaccessible or restricted areas, detecting ground movement, environmental changes, and infrastructure stability without the need for physical access. GNSS complements this by providing high-precision location data, ensuring accurate tracking of movements and changes in these areas. Together, InSAR and GNSS offer a comprehensive monitoring solution for regions that are difficult to access, ensuring continuous surveillance and reliable data for decision-making.

Natural Hazard Data for the Insurance Sector

InSAR offers valuable insights into ground movement and infrastructure stability, essential for assessing natural hazards such as earthquakes, landslides, and floods. It provides critical data for insurance companies to evaluate risks and inform policy decisions. GNSS enables accurate location tracking to assess the extent of damage in real time, supporting efficient claims processing and risk mitigation. Together, these technologies provide a comprehensive monitoring system that supports better risk assessment and management in the insurance industry.
