ABSTRACT:
A position, time location receiving system deriving its output position estimates from received inputs from a distributed array of pseudonoise multiplexed transmitter channels at determinable spatial positions. The receiving system has a plurality of delay lock loops, one for each transmitter channel. Control signals for the delay lock loops of each transmitter channel are derived from a current estimated location vector (x, y, z) and time.
