GeoGuard monitoring service
Precision Geodetic & Environmental Monitoring Service for Critical Infrastructures and Earth Observation
GeoGuard is an innovative end-to-end service for the continuous monitoring of critical infrastructure and natural hazards.
It includes activities and systems designed for the delivery of solutions, customized to different application scenarios, to provide accurate positioning with centimeter-level accuracy in near real-time, or millimeter-level accuracy for daily/sub-daily solutions.
In particular, GeoGuard includes:
• preliminary inspection activity of the site to be monitored, in order to design the most appropriate solution;
• deployment of the sensing infrastructure, composed by GeoGuard Monitoring Units, according to the site characteristics;
• connectivity setup between the sensing infrastructure and the GeoGuard Cloud;
• GeoGuard Cloud, where data are collected and processed. Positioning and management data are delivered to the customer information systems;
• online help desk service, to support the customer in the day-by-day operations;
• professional services: to design build and manage customized solutions according to the customer business needs.
GeoGuard System Architecture
The GeoGuard system architecture is constituted of two main components:
• GeoGuard Monitoring Unit (GMU): based on newly designed price-competitive Global Navigation Satellite System (GNSS) processor. The sensing infrastructure is composed of one or more GMU, integrated with additional sensing equipment according to the customer needs;
• GeoGuard Cloud: the system that collects and organizes the acquired data, verifies the data flow integrity, performs the positioning data processing and analyzes the results.
GeoGuard Monitoring Unit (GMU)
A GMU is a remote terminal unit specifically designed to operate in challenging environments. It can be powered in any location supporting AC, DC or solar power. GeoGuard Cloud can remotely manage the units via two-way communication. The GMU unit includes:
• Processing Module: it includes microprocessor unit and local storage unit;
• Communication Module: it includes the communication features with Ethernet, GSM/3G LTE and M2M radio connections;
• Positioning Module: it features a GNSS Processor and a 3-Axis MEMS accelerometer to detect the device position, orientation and vibrations;
• Sensing Module: it features digital, analog I/O and an industry standard communication bus to connect and monitor any sensor the specific application might require;
• Power Module: it provides power supply by alternate current (AC) and direct current (DC) from different sources, including photovoltaic panels.
GeoGuard Monitoring Units can create an autonomous local network, linked to the GeoGuard Cloud through a single point of external connection (GW).
The core of the GeoGuard service: receives and processes the data from the sensing infrastructure and provides the resulting information to the customer. It includes the following functions:
• Sensing infrastructure interface: receives the GNSS positioning/sensor raw data and the unit metadata from the sensing infrastructure;
• Remote GMU management: provides all the information needed to manage the service, including administrative and service level agreement data;
• Data processing: is tailored to best exploit the measurements of price-competitive GNSS receivers and is devoted to perform statistical and quality analyses of input observations and output results (detection of trends and sudden changes in position and sensors time series), in order to issue early warnings to the customer;
• End user service interface: exposes the information provided by the GeoGuard service in two different modes:
– a WEB Application enabling users to exploit the GeoGuard service functionalities according to the end user practices;
– a REST API allowing fast and easy integration of GeoGuard services into external management information systems.
Social & industrial challenges
From now to 2030 $57 trillion in infrastructure investment are estimated. $400 billion a year could be saved by getting more out of existing capacity. Precise and timely measurements of the geometry of critical infrastructure guarantee these results and help in the prevention of catastrophic failures and reduction of insurance costs.* Economic losses due to natural disasters (landslides, floods, earthquakes and drought) since 2000 are in the range of $2.5 trillion.** A proper monitoring system facilitates the development of hazards prediction to mitigate or eliminate the risk thus promoting management strategies.
GeoGuard is designed to face and respond to social and industrial challenges:
• safety of Critical Infrastructure;
• Natural Hazards prediction and risk control.
Precise and timely measurements of the infrastructure movements and deformations. In particular for:
• Transportation & travel, such as bridges, airports, harbors and railways;
• Water distribution, such as water tanks and pipelines;
• Telecommunication infrastructure such as data, cellular and broadcasting network towers;
• Domestic security for military purpose, such as radars and radio systems;
• Energy, such as dams for hydro power plants, towers for high voltage, wind farms; Oil & gas transportation and storage;
• Cultural heritage and large stadiums preservation.
Precise and timely measurements to predict hazards and mitigate or eliminate risks. In particular for:
• Subsidence & uplift due to natural phenomena or oil & gas production and storage;
• River floods;
• Extreme weather events.
