Abstract

1315512 Radio navigation INTERNATIONAL STANDARD ELECTRIC CORP 23 June 1970 [26 June 1969] 30334/70 Heading H4D Relates to a sector phase beacon transmitting pulse pairs. In order that the receiver can determine whether it is in that sector a further, spaced, beacon transmits a third pulse to define a hyperbola substantially coincident with the sector boundaries.
