ABSTRACT:
An apparatus for determining the position of an object which is moving along an axis at frequent intervals of time and without making mechanical contact with the object, comprising position determinator means for providing an accurate position determination of said object at relatively long intervals of time or position, means associated with said object comprised either of the combination of speedometer means and electronic integration means for time integrating the output of said speedometer means at relatively frequent time intervals for providing an instantaneous measurement signal or the combination of accelerometer means and electronic integration means for double time integrating the output of said accelerometer means at relatively frequent time intervals for providing an instantaneous measurement signal, and means for correcting the value of said instantaneous measurement signal at said relatively long intervals of time or position to be equal to said position determination made by said position determinator means.
