| 12. A method for determining position, said method comprising:
generating, by one or more ground transmitters in an array of ground transmitters, ranging signals associated with a wideband
code modulation with a chipping rate faster than 30 MHz,
receiving, by said one or more ground transmitters in said array, other ranging signals of one or more other ground transmitters
in said array; and
wherein said one or more ground transmitters in said array is adapted for self-surveying its location relative to locations
corresponding to said one or more other ground transmitters in said array.
