There is a slant of creation a radio receiving path for using in position location equipment on the basis of range difference measurements. Proposed radio receiving path allows to eliminate one of the most significant source of measurement errors – instability of phase-difference parameters of radio receiving paths area distributed receiving points of range difference position location system. There is a structural scheme developed, and experimental results are listed. It is shown that using proposed radio receiving path allows to reduce an error that they add to time difference measurement results up to 100 ps.
