Abstract
The authors have previously reported on the absolute distance measuring systems being developed at Lockheed Missiles and Space Company for use in space on large erectable satellites. One, a two-color CO2 laser system, has a precision of 0.05 pm for aligning optical elements. The second, a Helve phase modulated system, has a precision of 25 pm for the measurement and control of large antennae. The status of these systems is updated with emphasis on extended range distance measurements and work aimed at simplifying the systems. The application of real time distance measurement between satellites is discussed. A concept is presented which will measure absolute distance to 25 pm track angular position to 10 Arad and provide 20 MHz bandwidth communication between satellites several kilometers apart.
