Range data will be used to help navigate Voyager 2 to Neptune and the most distant planetary encounter ever attempted. In preparation for this challenging August 1989 planetary encounter, a new data type, known as 'three-way range', has been developed. With three-way ranging, a ranging signal generated at a ground station, received at the spacecraft and transponded to Earth is then received coherently at a second tracking station, which can be distant from the transmitting station. This paper contains analytic and operational descriptions of three-way range. Hardware modifications and design necessary for implementing this new data type are discussed. Preliminary assessments of three-way ranging performance are given and accuracies are discussed.
