A "rather exciting development" in the ability of manned spacecraft systems to navigate accurately should be available in 10 yr, General William J. Evans, Commander, Air Force Systems Command, told the 57th annual meeting of the American Defense Preparedness Assn. in Los Angeles. The NAVSTAR Global Positioning System, the "most precise and accurate positioning, velocity, and navigation assistance air or surface vehicles have ever had," may replace as many as five separate systems now required for these functions.
