Abstract: This paper discusses one-dimensional position measurement using pseudorandom encoding. An application in the navigation of automated guided vehicles is described. Special attention is paid to the problem of Pseudorandom/Natural code conversion and the solution how to reduce maximum time needed for conversion is proposed. A new method for serial reading of the pseudorandom code using two reading heads is also developed. This method eliminates systematic errors and makes the system resistant to oscillations in the movement course. A position transducer with 12 bit output resolution has been designed.
Key words: Measurement, pseudorandom encoding, code conversion, position transducer.
