A sensor network () as well as a method for monitoring a terrain () is specified. The sensor network () has a number of fixed-position sensors (&#x2033;), which can be deployed in the terrain (), and at least one programming module (), with the fixed-position sensors (&#x2033;) each being equipped with a communication device, with the at least one programming module having a position-finding device and a programming device (), in which case the position of the sensors (&#x2033;) can be determined by the position-finding device and can in each case be applied to the sensors (&#x2033;) by the programming device () via the communication device, and with the sensors (&#x2033;) being designed such that they themselves form a network. The sensor network () as well as the method, which is carried out in a manner corresponding to it, for monitoring the terrain () require sensors (&#x2033;) of simple design, and are thus associated with a cost advantage.

Sensor network and method for monitoring a terrain

A radio-controlled timepiece is controlled by time telegrams emitted by a regional transmitter. When the timepiece is out of the effective range of the regional transmitter, the timepiece is controlled by a local (i.e., close-range) transmitter which transmits time telegrams that have the same frequency and encoding as the time telegrams from the regional transmitter. The local transmitter receives time information from a remote source, such as navigational satellites, or alternatively a time server by way of the internet, in order to create the local time telegrams.
