1. Apparatus for accurately measuring distance comprising:
- a. a portable radar for measuring distances and directions from the radar to one or more surfaces within a structure;
b. a portable first global positioning satellite receiver, located a fixed measured distance from said radar; and
c. a computer connected to receive information from said radar and from said portable global positioning satellite receiver and configured to calculate a distance from said radar to a surface of said one or more surfaces within a structure using said information and said fixed measured distance.

Abstract
A micropower impulse radar is used to take measurements, such as those needed to establish room size and the dimensions and location of objects within the walls of a room. A computer controls the scanning of the radar and the collection of datapoints. A global positioning satellite (GPS) unit locates the precise portion of the radar and another unit loads a fixed referenced location to which all measurements from different rooms are baselined. By collecting points and referencing them to a common point or wireframe representation of a building can be developed from which "as built" architectural plans can be produced.
