  • Detection of road conditions using a beam from an external system i.e. GPS, DBS
    Patent number: 6922636
    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.
