Abstract
A device for determining ground surface condition, especially for roads includes receivers for receiving at least one scanning radiation component that is reflected from the scanned earth surface region, and contains surface condition information. Evaluation resources determine the surface state of the scanned ground surface region by evaluating the scanning radiation. The scanning radiation component comprises useable signal radiation of a foreign system and/or is generated by one or more satellites.

9. A system for determining the condition of a ground surface area, comprising:
-
a radiation source for irradiating said ground surface area;
at least one receiver for receiving at least radiation that emanates from said radiation source and is reflected from said ground surface area; and
a processor which processes received radiation to determine the condition of the ground surface area;
wherein the radiation source comprises a system that irradiates the ground surface area for a purpose other than determining ground surface conditions.
