Automated event sampling and real-time data access within hydrological measuring networks by means of low-earth-orbiting satellites

In the field of hydrogeological investigations event monitoring and event sampling are indispensable tools to get detailed information about parameters of the aquifer and the vulnerability. The use of event monitoring for microbiological investigations is a new field of activity, which was enabled by development of new communication structures and methods of analysing. The system, which is presented here, enables fully automated event sampling and real-time availability of data. By means of networking via Low Earth Orbiting Satellites data from the precipitation station (PS) in the catchment area are brought together with data of the spring sampling station (SSS) without the need of terrestrial infrastructure for communication and power supply. Therefore a completely automated event sampling procedure is made possible. Furthermore the whole course of input and output parameters, like precipitation (input system) and discharge (output system) and the status of the sampling system, is transmitted via LEO-Satellites to a Central Monitoring Station (CMS) which can be linked with a web-server to have unlimited real-time data access.
