Long-term monitoring

Project Description

Summary: Installation of a monitoring system to control a landslide

Clients: Servizio geologico della Provincia di Trento

Place: Imer (TN) (Italy)

Period: 2003 - N/A

Installation:

Structure's short description: The system is composed by 2 GPS measurement stations + 1 Laser and a Control Unit. The measurement frequencies are 2-4 measurements per day for the GPS, while for the laser it is one measurement every 10 minutes. The cellar modem (GSM) technology is used for the communication between the stations and the Control Unit. The reference station is connected directly to the power supply while the other two stations (mobile GPS station and laser station) are connected to solar panels.

Aim of monitoring: The project aim is to monitor the landslide to control the movements in the three directions and to documents the land movements.

Number of sensor: 2

Main Results: N/A

Some trees are used as targets for the laser measurements and as support for the GPS measurement station and antenna.

GPS reference antenna on the roof of the fire brigate building.

The GPS reference station is located by the fire brigate head quarters. The distance from the landslide is about 700m.
