The Legacy of Transit
Volume 19, Number 1 (January–March 1998)

This issue of the Technical Digest is dedicated to the many men and women at APL, the Navy, and supporting organizations who gave so much to bring a bold idea to life. In particular, this issue is dedicated to Frank T. McClure, who conceived the concept of Doppler navigation from the pioneering work of William H. Guier and George C. Weiffenbach, and to Richard B. Kershner, who turned McClure’s invention into a real operational system.The articles in this issue are only a sample of the many scientific and technological accomplishments of the Transit era.
