Laser technology has revolutionized range instrumentation by providing methods for gathering precise real time space position data. Current methods are tedious and susceptible to human error in both the data gathering and the subsequent analyses. This paper will discuss typical range instrumentation requirements with a comparison of solutions provided by laser technology and more conventional means. Concrete examples will be provided with the description of an existing laser system which was used as the principal space position test instrument. A movie will be shown demonstrating laser technology applied to determination of space position of aircraft, rockets, ballistics, rocket sleds and other objects. Also, examples of the data gathered with laser systems will be presented.
