Claim:
1. A system for guidance or navigation, the system comprising: a spatially-distributed architecture (SDA) of antenna arrays, the SDA having at least N members of antenna arrays spatially separated from each other, the N members transmitting uniquely coded signals, respectively, where N is an integer greater than or equal to two, a position and orientation of the antenna arrays of the SDA identifying a first coordinate system consisting of at least two orthogonal axes; a first receiver having a known position in the first coordinate system, the first receiver receiving reflections of the uniquely coded signals reflected by a non-cooperative object; a first processor in communication with the first receiver, the first processor in response to information from the first receiver, determining at least a position of the non-cooperative object in the first coordinate system based on the reflections of the uniquely coded signals; a platform separated from the SDA of antenna arrays, the platform having a second receiver disposed thereon, the second receiver directly receiving the uniquely coded signals transmitted by the SDA; and a platform processor in communication with the second receiver, the platform processor, in response to information from the second receiver, determining at least a position of the platform in the first coordinate system based on one or more characteristics of the uniquely coded signals received by the second receiver.
